### 为什么打造前端工作流
事实上 ， 现在很多的编辑器都有可以做代码检查的插件 ， 这个对于开发者个人来说足够了， 但是对于一个开发团队来说略显不足
代码里面的一些坏味道不能得到规范 ，从而降低了代码质量
git hooks的作用就是用来做代码提交时候的一道检查
### eslint
代码质量扫描（未使用变量 ， 三等号， 全局变量声明等），一定注意全局安装
### prettier
代码格式校验（单行长度， tab长度， 空格）团队代码风格统一，
prettier目前支持前端大部分的语言处理 ，包括js ts css scss less jsx vue json md等 , 几乎用一个工具搞定所有代码的格式问题
### eslint, prettier结合使用
这简书讲解eslint prettier可以 https://www.jianshu.com/p/dd07cca0a48e
###### 配合使用原因
eslint的规则不如prettier健全, 对于自动修复代码格式推荐使用prettier --write
###### 配合使用存在问题
1. 两者规则出现交集 ， 去掉eslint规则 ， 使用prettier 规则
eslint-plugin-prettier：将prettier规则作为eslint规则 ， 对不符合规则的调用prettier进行提示
eslint-config-prettier： 关闭eslint一些与prettier冲突的规则 ，那样一些错误不会出现两次
官方称eslint-plugin-prettier需要与eslint-config-prettier搭配食用才能获得最佳效果。
### husky
git 钩子插件， 配合npm script的钩子依赖插件husky
本地钩子 precommit prepush
远程仓库钩子prereceive...
为什么添加远程钩子 ， git在commit的时候是可以跳过本地的钩子的 --no-verify | -n
### lint-staged
专门做扫描优化 ， 只针对git 暂存区的文件进行代码扫描
在package.json 中lint-staged不管是js还是scss在修复代码格式的时候都是用的prettier --write ， ！！！prettier的参数还没有细看暂时不管
```
"lint-staged": {
"src/**/*.{js,scss}": [
"prettier --write",
"git add"
]
}
```
之前一直以为js的代码格式修复用eslint --fix
```
"lint-staged": {
"src/**/*.{js}": [
"prettier --write",
"eslint --fix",
"git add"
]
}
```
css|scss文件使用stylelint --fix
```
"lint-staged": {
...
"src/**/*.{css|scss}": [
"stylelient",
"git add"
]
}
```
控制台就一直会报错 ， 这个错
```
→
× "stylelint" found some errors. Please fix them and try committing again.
Error: No files matching the pattern "F:\studyAndRemote\study_git_hooks\src\scss\index.scss" were found
```
最后发现create-reate-app新版本也加上了eslint prettier lint-staged, 参照了人家的package.js发现代码格式的修复就用了prettier, 上面提到
prettier支持大部分前端语言的规范以及格式修复
### error Parsing error: Unexpected token
解决方法
npm install babel-eslint --save
然后在 .eslintrc.js 中加入代码解析"parser": "babel-eslint"

refs/heads/main | <file_sep># EECS738 Project3 Says One Neuron To Another
EECS738 Machine Learning course project3. Two deep neural networks have been implemented: a Multilayer Perceptron (MLP) with multiple linear layers and a typical Convolutional Neural Network (CNN). Two image datasets are selected: **MNIST** handwriting characters and **GTSRB** traffic sign recognition. Only third-party packages used in all implementations are **numpy**, **pandas**, **python-mnist** and **Pillow**.
## Function Checklist
These functions are implemented manually in this project in a detailed manner:
* Fully-Connected layers.
* Convolutional layers.
* Batch Normalization 2d & 1d.
* Dropout.
* Maxpooling.
* Activation functions: Sigmoid and ReLU.
* Data loading and data prepossessing (normalization).
* Forwarding and backpropagation using BGD.
* Cross-entropy loss.
## Dataset
* [Modified National Institute of Standards and Technology database (MNIST)](http://yann.lecun.com/exdb/mnist/). This is possibly one of the most commonly-used and simplest dataset in image tasks in machine learning, which combines with different images of hand-written digits. The sizes of training dataset and testing dataset are 60,000 and 10,000 each. Though the attached webpage link seems not to be working, the dataset can be directly accessed by package [python-mnist](https://github.com/sorki/python-mnist). Images and grey-scale with a size of 28\*28 each. Ten labels in total range from 0, 1, 2... to 9.
* [The German Traffic Sign Recognition Benchmark (GTSRB)](https://benchmark.ini.rub.de/gtsrb_dataset.html). This is a more challenging dataset with images of traffic signs captured in real street views. Each image contains exactly one traffic sign, usually located right at the middle. There are 43 labels in total, representing different types of traffic signs, and more than 50,000 samples. Recognition of these signs is much more difficult and practically significant, as many of the signs have similar shapes and colors.
## Ideas and Thinking
* **DNN**: In my opinion, deep neural networks are basically a complex but repetitive variant of weighted function with non-linear operators added. What deep learning does is to tweak the weights gradually by iterating over a large (usually) number of examples. If taking a task as a process of building sand castles, the precise solution will be like building by crafting structures and shapes, and the deep learning will be like flapping and rubbing by frequently looking at samples. Outcome of deep learning are set of parameters to mimic and map certain features, known as saliency, to high confidence scores in exact dimension. This 'learning' process imitates the process of human learning (recognition or understanding), setting up correlations between 'name/meaning' and 'features' through repetitively getting exposed to examples and strengthening neuron connections.
* **Activation Functions**: An important component of deep learning is activation function, which significantly accounts for deep learning's success. The non-linear properties of deep learning are largely contributions of activations. What activations really does is to differentiate neurons to respond to unique features. After activation, some of the neurons will be silent for specific features, while others will not. In this way, the deep neural networks are no longer an inflexible combination of weighted values, but a instead dynamic system where each unit has a 'switch'. This is done mainly by the cut-off (e.g. ReLU) or downgrade (e.g. Sigmoid) in gradients in backpropagation. Once a neuron get silent for certain feature distribution, little changes will be witnessed in its parameters when updating. In forwarding cases, different parts of neurons will 'switch on' for different feature distribution, which greatly increase the fitting ability of the function in limited parameter space.
* **Backpropagation**: Backpropagation is a rather simple but important process. By calculating the partial gradient of the model output over parameters, the parameters are updated from layer to layer to increase highly-activated neurons' contribution to current label, and decrease noises from unrelated neurons.
* **Testing**: After iterations over training samples, the model parameters are tuned to distribution of the task domain, which expects the ability to guide new examples from the same domain into explainable outputs. Different from training, some operators, e.g. dropout and batch normalization, tend to stay static in testing phase to expect stable behaviors, e.g. to eliminate quantity influence and random errors.
## Setup
### Environment
* Python 3.9
* MacOS or Linux
### Package
* Recommend setting up a virtual environment. Different versions of packages may cause unexpected failures.
* Install packages in **requirements.txt**.
```bash
pip install -r requirements.txt
```
* I've updated my environment to python3.9 and there is inconsistency between my previous course projects and this one. Sorry for any possible troubles.
## Usage
### Positional & Optional Parameters
* **data**: Dataset name (task) to choose from 'mnist' and 'gtsrb'.
* **-p**: Whether to load pre-trained model parameters. The parameters for MNIST model is saved in ['./paras'](https://github.com/liuzey/EECS738_Project3/tree/main/paras). The parameters for GTSRB model is saved in ['./paras_save'](https://github.com/liuzey/EECS738_Project3/tree/main/paras_save). (Default: False).
* **-s**: Whether to save the trained model parameters (Default: False).
### Example
```bash
python main.py 'gtsrb' -s 1 -p 1
```
* 'gtsrb': GTSRB recognition task.
* -p: Model parameters are pre-trained and loaded.
* -s: Trained parameters are saved periodically.
## Result Analysis
Training records and results are saved in ['./records'](https://github.com/liuzey/EECS738_Project3/tree/main/records), which shows indeed a decrease in loss. This indicates the training is working in some sense. However, the accuracy doesn't show great improvements. This is a rough implementation of neural networks, which has much space for improvements, especially in gradient calculation. I remain these as my future work.
### MLP
The structure of the MLP model used in MNIST task is
| MLP |
| :-------------: |
| FC1(1\*28\*28, 100) |
| FC2(100, 10) |
All linear layers have biases.
### CNN
For this convolutional neural network in this project, the convolutional kernels is set at (3,3). The structure of the CNN model used in GTSRB task is
| CNN |
| :-------------: |
| Conv1(channels=32, stride=(1, 1), padding=(0, 0)), BatchNorm(32), ReLU |
| Conv2(channels=64, stride=(2, 2), padding=(1, 1)) |
| Conv3(channels=64, stride=(1, 1), padding=(0, 0)), BatchNorm(64), ReLU, Dropout |
| Conv4(channels=128, stride=(2, 2), padding=(1, 1)) |
| Conv5(channels=128, stride=(1, 1), padding=(0, 0)), BatchNorm(128), ReLU |
| FC1(128\*5\*5, 100), ReLU |
| FC2(100, 43) |
## Technical Details
### Activations
[Sigmoid](https://github.com/liuzey/EECS738_Project3/blob/e65024acd5599e13549a8742eb563814eb168b1a/MLP.py#L94):
[ReLU](https://github.com/liuzey/EECS738_Project3/blob/e65024acd5599e13549a8742eb563814eb168b1a/MLP.py#L49) returns the non-negative value of inputs.
### Dropout
[Dropout](https://github.com/liuzey/EECS738_Project3/blob/e65024acd5599e13549a8742eb563814eb168b1a/MLP.py#L80) turns values into 0 at a probability of 50% in training phase, and multiplies value by 0.5 in testing phase.
### Batch Normalization
[BatchNorm](https://github.com/liuzey/EECS738_Project3/blob/e65024acd5599e13549a8742eb563814eb168b1a/CNN.py#L136) follows the similar procedure as normalization over batch, but the final inputs is weighted by gamma and added bias beta. The gamma and beta are adjusted in the training phase. In the testing phase, the outputs are calculated with remembered global values.
### Convolutional Layer
[Forwarding](https://github.com/liuzey/EECS738_Project3/blob/e65024acd5599e13549a8742eb563814eb168b1a/layers.py#L15):

### Fully-connected Layer
[Forwarding](https://github.com/liuzey/EECS738_Project3/blob/e65024acd5599e13549a8742eb563814eb168b1a/layers.py#L57):

## Notes
* Cross entropy loss is only used for printing in a perceptual manner in MLP, but does not participate in actual backpropagation. For CNN records, the loss is the sum of gradient in the last layer.
* Training the CNN for GTSRB can be highly time-consuming, which needs my further improvements.
* I've tried different MLP structures in MNIST task and different learning rates.
* I find it difficult to choose initial parameters, especially for linear layers in adopted rough propagation/gradient strategy. The large dimensions will often make the results big and shrink difference between features, losing expressive ability in sigmoid activations and causing troubles in exponential calculations in softmax.
* In the final version, maxpooling and BatchNormaliztion1d are eliminated for simplification. For maxpooling, the backpropagation requires more work. For batch1d, it makes values deviated largely and result in minus values, which requires more work. Maxpooling should be implemented in a very similar way as Dropout function.

## Services Example
### Send SMS message
You can send SMS messages using the transmission gate to ensure the privacy of information and the speed of sending and ensure they arrive, and this portal provid the ability to sending messages to many numbers at once and without any effortless and tired, is the gate to send and receive messages using JSON technology And These an example of how to use the portal:
```php
<?php
require_once('Mobily_sms.inc');
$sms = new MobilySms('user name','password','ApiKEY');
$result=$sms->sendMsg('This is Message','9662222222222,9662222222222,9662222222222','NEW SMS','17:30:00','12/30/2017',1,'deleteKey','curl');
?>
```
### Send SMS using message Template
This portal offers the ability to send SMS messages using a unified message template for different numbers. This portal allows you to add fixed message text and put symbols in it. This portal transmits the information of each number with the symbols in the message to form a message for each number. the operation :
```php
<?php
require_once('Mobily_sms.inc');
$sms = new MobilySms('user name','password','ApiKEY');
$msg = "Welcome (1)، Your subscription date is up to (2)";
$msgKey = "(1),*,William,@,(2),*,12/10/2008***(1),*,jack,@,(2),*,10/10/2008";
$numbers='96622222222222,96622222222222';
$result=$sms->sendMsgWK($msg,$numbers,'aljauoni',$msgKey,'12:00:00','12/27/2017',0,'deleteKey','curl');
?>
```
### Balance Inquiry
You can inquire about mobily account balance through this portal by adding mobile number or Api KEY , this portal sends and returns JSON data and the following example shows how to use this portal :
```php
<?php
require_once('Mobily_sms.inc');
$sms = new MobilySms('user name','password','ApiKEY');
$result=$sms->balance('curl');
?>
```
### Forget Password
You can retrieve the mobily account password through this portal by adding the mobile number or Api KEY to retrieve its password and the way to send the password either on the mobile number or on the email of the account, and this portal sends and returns data from JSON Type The following example shows how to use this portal:
```php
<?php
require_once('Mobily_sms.inc');
// you must insert just user name or ApiKEY
$sms = new MobilySms('user name','password','ApiKEY');
// 1: that means send password to account mobile
$result=$sms->forgetPassword(1,'ar','curl');
// or you can use
// 2: that means send password to account email
$result=$sms->forgetPassword(2,'ar','curl');
?>
```
### Change Password
You can change the password for mobily account through this portal by adding the mobile number or Api KEY to change its password and old and new password, and this portal sends and returns data of type JSON. , And as an example of the required data:

// At the same time, for JSON: print should insert all elements

<file_sep>// Package log is a custom logging library. It defines a type, Logger,
// with methods for formatting output. Here's an overview of its
// main features:
//
// - Log Levels: This package supports various log levels, including Panic,
// Fatal, Error, Warn, Info, Debug, Trace. Each level has three methods:
// plain (like Info), formatted (like Infof), and line-based (like Infoln).
// This distinction allows for flexible log message creation.
//
// - Flexible Outputs: The logger is designed to output logs to multiple
// destinations (referred to as "Outputs" in the code).
//
// - Prefixing: Each logger can have a prefix, which can be set during
// creation with the New function or later with SetPrefix.
//
// - Skipping Stack Frames: The package also provides a mechanism to skip
// a certain number of stack frames when logging, which can be useful when
// wrapping this logger inside other libraries or utilities.
//
// - Singleton Pattern: The package uses a singleton pattern to instantiate
// a single logger instance that can be used throughout an application.
// It provides global functions that operate on this instance.
//
// - Panic and Fatal: The Fatal functions call os.Exit(1) after writing
// the log message. The Panic functions call panic after writing the
// log message.

# log
The log module encompasses methods for comprehensive logging, which comprises a variety of logging levels:
- Panic
Panic typically signifies that something has gone unexpectedly awry. It's primarily utilized to swiftly halt on errors that shouldn't surface during regular operation, or those we aren't equipped to handle smoothly.
- Fatal
Fatal corresponds to situations that are immensely disastrous for the application. The application is on the verge of terminating to avert any sort of corruption or severe problem, if feasible. Exit code is 1.
- Error
An error represents a significant issue and depicts the failure of something crucial within an application. Contrary to FATAL, the application itself is not doomed.
- Warn
This log level implies that an application might be experiencing a problem and an unusual situation has been detected. It's an unexpected and unusual issue, but no real damage is done, and it's uncertain whether the problem will persist or happen again.
- Info
The messages at this level relate to standard application behavior and milestones. They offer a framework of the events that took place.
- Debug
This level is meant to provide more detailed, diagnostic information than the INFO level.
- Trace
This level offers incredibly detailed information, even more so than DEBUG. At this level, every possible detail about the application's behavior should be captured.
## Installation
To install this module use `go get` as:
```
$ go get -u github.com/goloop/log
```
## Quick Start
To use this module import it as:
```go
package main
import (
"os"
"github.com/goloop/log"
"github.com/goloop/log/layout"
"github.com/goloop/log/level"
// It is not necessary to import this module, the three-valued logic
// constants can be represented using integers where: -1 is False,
// 0 is Unknown, and 1 is True.
"github.com/goloop/trit"
)
func main() {
// Open the file in append mode. Create the file if it doesn't exist.
// Use appropriate permissions in a production setting.
file, err := os.OpenFile(
"errors.log",
os.O_APPEND|os.O_CREATE|os.O_WRONLY,
0644,
)
if err != nil {
log.Fatal(err)
}
// Defer the closing of the file until the function ends.
defer file.Close()
// Set the outputs of the log to our file.
// We can set many different outputs to record
// individual errors, debug or mixed data.
err = log.SetOutputs(
log.Output{
Name: "stdout",
Writer: os.Stdout,
Levels: level.Debug | level.Info | level.Warn | level.Error,
Layouts: layout.Default,
WithColor: 1, // or trit.True, see github.com/goloop/trit
},
log.Output{
Name: "errorsJSONFile",
Writer: file,
Levels: level.Warn | level.Error, // only errors and warnings
Layouts: layout.Default,
TextStyle: trit.False, // or just -1
},
)
if err != nil {
log.Fatal(err)
}
// A message will be output to a file and to the console.
// * stdout and errorsJSONFile has Error level.
log.Errorln("This is a test log message with ERROR.")
// A message will be output to the console only.
// * stdout has Debug level, but errorsJSONFile has not.
log.Debugln("This is a test log message with DEBUG.")
}

refs/heads/master | <file_sep># ccng-routes
**An api routes print tool for Cloud Foundry CCng (cloud_controller_ng)**
The Cloud Foundry CCng (cloud_controller_ng) component generates its API routes dynamically. This tool prints the generated routes in Ruby-on-Rails "rake routes" style.
## Example
[Routes for CCng API v2.79.0](https://gist.github.com/nota-ja/d6a29229f21b863ba643ca584ef9e5e3)
## Prerequisites
- git
- ruby
- bundler gem
## Usage
### Simple
- Clone this repository
```
git clone https://github.com/nota-ja/ccng-routes.git
```
- Change directory to the cloned repository and run ccng-routes.sh
```
cd ccng-routes
./ccng-routes.sh
```
### Advanced
You may specify a revision to generate api routes.
```
CCNG_REV=a_git_revision ./ccng-routes.sh
```
Additionally, You may use an exsiting cloud_controller_ng repository.
```
CCNG_REPO=path/to/cloud_controller_ng ./ccng-routes.sh
```
As the details described below, this tool touches the targetted cloud_controller_ng repository.
So it is recommended to use a newly cloned repository.
The script ccng-routes.sh clones the cloud_controller_ng repository to directly under this tool's directory and use it if the environment variable CCNG_REPO is not given.
The routes info is printed to stderr. So if you want to write routes info alone to a file, just do like:
```
CCNG_REPO=path/to/cloud_controller_ng CCNG_REV=a_git_revision ./ccng-routes.sh 2> routes.txt
```
## Details
The ccng-routes.sh script is based on 'routes' task in the Rakefile. You can run the task independently as:
```
BUNDLE_GEMFILE=path/to/cloud_controller_ng/Gemfile bundle exec rake routes
```
Because the task reuses gems used in cloud_controller_ng, BUNDLE_GEMFILE environment variable must be specified properly.
The rake task also accepts CCNG_REPO environment variable described above.
The task actually does following operations:
1. (preparation)
1. Use CCNG_REPO environment variable as cloud_controller_ng repo. If not defined, $PWD/cloud_controller_ng is set.
2. Clone cloud_controller_ng repo if not exist.
2. Apply the patch (routes.rb.patch), that adds printing facility into dynamic route generation process, to lib/cloud_controller/rest_controller/routes.rb in cloud_controller_ng repo.
3. Execute the route-defining code by requiring lib/cloud_controller.rb in cloud_controller_ng repo.
4. Unpatch the patch applied.
When you want to get CCng routes of a specific revision with the rake task, just cd to the cloud_controller_ng repo, checkout the revision, sync / update its submodule, run bundle install to install gems, then back to this tool's directory and run the rake task.
```
pushd path/to/cloud_controller_ng
git checkout a_git_revision
git submodule sync; git submodule update --init --recursive
bundle install --path vendor/bundle
popd
CCNG_REPO=path/to/cloud_controller_ng BUNDLE_GEMFILE=path/to/cloud_controller_ng/Gemfile bundle exec rake routes
```
As a matter of fact, the ccng-routes.sh script executes the process described above.
## Tips
### Post production
A generated route may contain an ID of Proc object and a path to the cloud_controller_ng repo when the action part of the route is defines as a Proc object. It's not convenient to compare two sets of API routes of different revisions and / or in different paths.
I am using the following script to remove those extra information:
```
cat routes.txt | perl -lane 's/Proc:0x[0-9a-f]+@.+\/cloud_controller_ng\//Proc:\@/; print $_' | sort > marshalled.routes.txt
```
(Assume routes.txt is a set of generated routes)
If you make another marshalled set of routes, then you can compare the two route sets.
## Known Issue(s)
Sometimes rake may fail because of version unmatch of nokogiri's dynamically compiled library.
```
rake aborted!
dlopen(cloud_controller_ng/vendor/bundle/ruby/1.9.1/gems/nokogiri-1.6.1/lib/nokogiri/nokogiri.bundle, 9): Library not loaded: cloud_controller_ng/vendor/bundle/ruby/1.9.1/gems/nokogiri-1.6.1/ports/x86_64-apple-darwin13.3.0/libxml2/2.8.0/lib/libxml2.2.dylib
```
A workaround is:
```
pushd $CCNG_REPO

# Water Jug Puzzle (The Die Hard Riddle)
We would like to collect a specific amount of water in a bottle when we have k water bottles with prespecified capacity and only the following operations are allowed:
* Fill up either bottle completely.
* Empty either bottle completely.
* Pour water from one bottle to the other until the poured bottle becomes empty or the other bottle becomes full.
Water Jug Puzzle was solved using Breadth-First Search in
* Sequential and
* Master-worker cluster pattern
Test case: two bottles of size 5, 3 and target amount of 4.
Solution given by Sequential and cluster implementation:
```
The solution to water jug puzzle with 2 bottles of size [5, 3] is: [0, 0]->[5, 0]->[2, 3]->[2, 0]->[0, 2]->[5, 2]->[4, 3].
```
To compare sequential and cluster implementation, 10 bottles of size 3,5,7,13,19,29,31,37,39,41 with target amount 21 was considered.
Solution:
```
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0]-> [0, 0, 0, 0, 19, 0, 0, 0, 0, 0]-> [0, 0, 0, 0, 19, 0, 0, 0, 0, 41]-> [0, 0, 0, 0, 0, 0, 0, 0, 19, 41]-> [0, 0, 0, 0, 0, 0, 0, 0, 39, 21].
```
Sequential time | Parallel time| Speedup
---|---|---
7019|4340|7019/4340 = 1.6
### To run Sequential program,
```
# Compile the java file
javac waterJugPuzzle.java
# Execute compiled java class file
java waterJugPuzzle
```
### To run parallel program
```
# Compile the parallel program
javac WaterJugClu.java
# Make jar file from compiled class file
jar cf WaterJugClu.jar *.class
# Execute the jar created
java pj2 jar-WaterJugClu.jar WaterJugClu
```

# Dapr $dapr_version
We're happy to announce the release of Dapr $dapr_version!
We would like to extend our thanks to all the new and existing contributors who helped make this release happen.
**Highlights**
If you're new to Dapr, visit the [getting started](https://docs.dapr.io/getting-started/) page and familiarize yourself with Dapr.
Docs have been updated with all the new features and changes of this release. To get started with new capabilities introduced in this release, go to the [Concepts](https://docs.dapr.io/concepts/) and the [Developing applications](https://docs.dapr.io/developing-applications/).
$warnings
See [this](#upgrading-to-dapr-$dapr_version) section on upgrading Dapr to version $dapr_version.
## New in this release
$dapr_changes
## Upgrading to Dapr $dapr_version
To upgrade to this release of Dapr, follow the steps here to ensure a smooth upgrade. You know, the one where you don't get red errors on the terminal.. we all hate that, right?
### Local Machine / Self-hosted
Uninstall Dapr using the CLI you currently have installed. Note that this will remove the default $HOME/.dapr directory, binaries and all containers dapr_redis, dapr_placement and dapr_zipkin. Linux users need to run sudo if docker command needs sudo:
```bash
dapr uninstall --all
```
Next, follow [these](https://github.com/dapr/cli#installing-dapr-cli) instructions to install the latest CLI version, or alternatively download the latest and greatest release from [here](https://github.com/dapr/cli/releases) and put the `dapr` binary in your PATH.
Once you have installed the CLI, run:
```bash
dapr init
```
Wait for the update to finish, ensure you are using the latest version of Dapr($dapr_version) with:
```bash
$ dapr --version
CLI version: $dapr_version
Runtime version: $dapr_version
```
### Kubernetes
#### Upgrading from previous version
If you previously installed Dapr using Helm, you can upgrade Dapr to a new version.
If you installed Dapr using the CLI, go [here](#starting-fresh-install-on-a-cluster).
##### 1. Get the latest CLI
Get the latest version of the Dapr CLI as outlined above, and put it in your path.
You can also use the helper scripts outlined [here](https://github.com/dapr/cli#installing-dapr-cli) to get the latest version.
##### 2. Upgrade existing cluster
First, add new Dapr helm repository(see [breaking changes](#breaking-changes)) and update your Helm repos:
```bash
helm repo add dapr https://dapr.github.io/helm-charts/ --force-update
helm repo update
```
Run the following commands to upgrade the Dapr control plane system services and data plane services:
* Export certificates
```
dapr mtls export -o ./certs
```
* Updating Dapr control plane pods
* Using the certs exported above, run the following command:
```
helm upgrade dapr dapr/dapr --version $dapr_version --namespace dapr-system --reset-values --set-file dapr_sentry.tls.root.certPEM=./certs/ca.crt --set-file dapr_sentry.tls.issuer.certPEM=./certs/issuer.crt --set-file dapr_sentry.tls.issuer.keyPEM=./certs/issuer.key
```
* Wait until all the pods are in Running state:
```
kubectl get pods -w -n dapr-system
```
* Verify the control plane is updated and healthy:
```
$ dapr status -k
NAME NAMESPACE HEALTHY STATUS REPLICAS VERSION AGE CREATED
dapr-dashboard dapr-system True Running 1 $dapr_dashboard_version 15s $today 13:07.39
dapr-sidecar-injector dapr-system True Running 1 $dapr_version 15s $today 13:07.39
dapr-sentry dapr-system True Running 1 $dapr_version 15s $today 13:07.39
dapr-operator dapr-system True Running 1 $dapr_version 15s $today 13:07.39
dapr-placement dapr-system True Running 1 $dapr_version 15s $today 13:07.39
```
* Updating the data plane (sidecars)
* Next, issue a rolling update to your Dapr enabled deployments. When the pods restart, the new Dapr sidecar version will be picked up.
```
kubectl rollout restart deploy/<DEPLOYMENT-NAME>
```
All done!
#### Starting fresh install on a cluster
If you previously installed Dapr on your Kubernetes cluster using the Dapr CLI, run:
*Note: Make sure you're uninstalling with your existing CLI version*
```bash
dapr uninstall --kubernetes
```
It's fine to ignore any errors that might show up.
If you previously installed Dapr using __Helm 2.X__:
```bash
helm del --purge dapr
```
If you previously installed Dapr using __Helm 3.X__:
```bash
helm uninstall dapr -n dapr-system
```
Update the Dapr repo:
```bash
helm repo update
```
If you installed Dapr with Helm to a namespace other than `dapr-system`, modify the uninstall command above to account for that.
You can now follow [these](https://docs.dapr.io/getting-started/install-dapr/#install-with-helm-advanced) instructions on how to install Dapr using __Helm 3__.
Alternatively, you can use the newer version of CLI:
```
dapr init --kubernetes
```
##### Post installation
Verify the control plane pods are running and are healthy:
```
$ dapr status -k
NAME NAMESPACE HEALTHY STATUS REPLICAS VERSION AGE CREATED
dapr-dashboard dapr-system True Running 1 $dapr_dashboard_version 15s $today 13:07.39
dapr-sidecar-injector dapr-system True Running 1 $dapr_version 15s $today 13:07.39
dapr-sentry dapr-system True Running 1 $dapr_version 15s $today 13:07.39
dapr-operator dapr-system True Running 1 $dapr_version 15s $today 13:07.39
dapr-placement dapr-system True Running 1 $dapr_version 15s $today 13:07.39
```
After Dapr $dapr_version has been installed, perform a rolling restart for your deployments to pick up the new version of the sidecar.
This can be done with:
```
kubectl rollout restart deploy/<deployment-name>
```

<file_sep>**_WebRec_**
**General**
The purpose of this code is to provide
a REST-ful API on top of the Lenskit
package.
**_Local verson_**
**Get started**
To test the API, you can follow next steps:
1) Download this code
2) Install Flask and install connexion
3) Run app.py
4) Go to localhost:5000/ui
5) Test the API
**File Structure**
**App.py** is the controller of this code, it starts the server and connects to the swagger file
**swagger.yml** describes the API and configures the endpoints of the server
For each operation id (e.g. operationId: rating.ratings_user) there needs to be
an according file (rating.py) with corresponding function (ratings_user) that has the same
parameters as described in the parameters section (e.g. user_id)
**recommendation.py** is the file that creates the recommendations. In this case,
it uses the Lenskit package and the Movielens dataset to generate recommendations. In case
you have your own back end, you need to change this file.
**_Deployment_**
We used docker to wrap up the code
and its dependencies into a container.
The reason for this wrapping is to enable
a fast deployment on different servers.
The docker version used for testing is
**18.03.0-ce**
**Get started**
1. Install docker
2. Download the code
3. Go to the folder
```sh
$ cd path/to/Webrec
```
4. Remove the running docker (if needed)
```sh
$ docker rm imagerun
```
5. Build the image
```sh
$ docker build -t imagebuild .
```
6. Run the image
a) interactive (debug)
b) normal
c) background
```sh
$ docker run -it --name imagerun -p 4000:80 imagebuild /bin/bash
$ docker run --name imagerun -p 4000:80 imagebuild
$ docker run -d -p 4000:80 imagebuild
```
7. Test if it is working by checking
`localhost:4000/Home`
<file_sep># Use an official Python runtime as a parent image
FROM continuumio/anaconda3
# Set the working directory to /app
WORKDIR /app
# Copy the current directory contents into the container at /app
COPY . /app
RUN conda install flask
RUN conda install -c lenskit lenskit
RUN conda install -c conda-forge flask-restful
# Make port 80 available to the world outside this container
EXPOSE 80
# Define environment variable
ENV NAME World
# Run app.py when the container launches
CMD ["python", "app.py"]
# 1) remove the old dockers
# 2) build the image
# 3) run interactive shell
# 4) run image
# 5) run image in background
# docker rm imagerun
# docker build -t imagebuild .
# docker run -it --name imagerun -p 5000:5000 imagebuild /bin/bash

# checkout-net-shopping-api
### Requirements
.Net Framework 4.5 and later
### How does checkout shopping api operate
This Api enable you to store a list of items that you want to purchase at end of each month.
For example as it has been given in your question that it shall be able to tore a drink.
In addition a shopping list can contain specific type or category of items such as stationary items.
Therefore this Api has cater for that. A sample response can be as follows :
```html
GET : http://localhost:49707/api/Shopping
```
response:
```javascript
{"drinks": [
{"Id":1,"name":"pepsi","quantity":1,"price":15.0,"DatePurchased":"0001-01-01T00:00:00"},
{"Id":2,"name":"fanta","quantity":1,"price":15.0,"DatePurchased":"0001-01-01T00:00:00"},
{"Id":3,"name":"sprite","quantity":1,"price":15.0,"DatePurchased":"0001-01-01T00:00:00"}],
"stationary":[ {"Id":4,"name":"pen","quantity":1,"price":15.0,"DatePurchased":"0001-01-01T00:00:00"},
{"Id":5,"name":"eraser","quantity":1,"price":15.0,"DatePurchased":"0001-01-01T00:00:00"}]}
```
If you want to retrieve only drinks as per your requirements. Just 'type=drinks as a param':
```html
GET : http://localhost:49707/api/Shopping?type=drinks
```
response:
```javascript
[
{"Id":1,"name":"pepsi","quantity":1,"price":15.0,"DatePurchased":"0001-01-01T00:00:00"},
{"Id":2,"name":"fanta","quantity":1,"price":15.0,"DatePurchased":"0001-01-01T00:00:00"},
{"Id":3,"name":"sprite","quantity":1,"price":15.0,"DatePurchased":"0001-01-01T00:00:00"}
]
```
The shopping api has been design using a repository pattern since the data will be stored
at least for now in an in memory data store thus avoiding duplication of logic to access and store our data.
##### Repository/container for our shopping item
```csharp
namespace CHCKOShoppingApi.Models
{
interface IShoppingRepository
{
Dictionary<string, List<Item>> GetAll();
IEnumerable<Item> getByType(string itemType);
Item getItem(string type, string itemName);
Item getItem(string type, int id);
List<Item> Add(string itemType, List<Item> items);
void Delete(string type, int id);
bool Update(string type, int id, Item item);
}
}
namespace CHCKOShoppingApi.Models
{
class ShoppingRepository : IShoppingRepository
{
public static ShoppingRepository shoppingBasket= null;
public static readonly Dictionary<string, List<Item>> Items = new Dictionary<string, List<Item>>();
static List<Item> items = new List<Item>
{
new Item {Id=1, name = "pepsi", price = 15, quantity = 1 },
new Item {Id=2, name = "fanta", price = 15, quantity = 1 },
new Item {Id=3, name = "sprite", price = 15, quantity = 1 },
};
private ShoppingRepository() {}
public void initRepository()
{
addItems("drinks", items);
}
public static ShoppingRepository getInstance()
{
if (shoppingBasket == null)
{
shoppingBasket = new ShoppingRepository();
Items.Add("drinks", items);
return shoppingBasket;
}
else
return shoppingBasket;
}
public void addItems(string type,List<Item> items)
{
if (!Items.ContainsKey(type))
{
Items.Add(type, items);
}
else
{
foreach (Item item in items)
Items[type].Add(item);
}
}
public Dictionary<string, List<Item>> GetAll()
{
return Items;
}
public IEnumerable<Item> getByType(string itemType)
{
return Items[itemType];
}
public Item getItem(string type, string itemName)
{
return Items[type].Find(i => i.name == itemName);
}
public Item getItem(string type, int itemId)
{
return Items[type].Find(i => i.Id == itemId);
}
public List<Item> Add(string itemType,List<Item> items)
{
ShoppingRepository.getInstance().addItems(itemType, items);
return items;
}
public void Delete(string type,int id)
{
var item = Items[type].FirstOrDefault(i => i.Id == id);
if (item != null)
{
Items[type].Remove(item);
}
}
public bool Update(string type,int id,Item item)
{
Item rItem = Items[type].FirstOrDefault(p => p.Id == id);
if (rItem != null)
{
rItem.name = item.name;
rItem.quantity = item.quantity;
rItem.price = item.price;
return true;
}
return false;
}
}
}
```
##### ShoppingItem model
```csharp
namespace CHCKOShoppingApi.Models
{
public class Item
{
private DateTime datePurchased;
[Key]
public int Id { get; set; }
public string name { get; set; }
public int quantity { get; set; }
public double price { get; set; }
public DateTime DatePurchased
{
get { return datePurchased; }
set { datePurchased = new DateTime(); }
}
}
}
```
##### ShoppingApi controller
```csharp
namespace CHCKOShoppingApi.Controllers
{
public class ShoppingController : ApiController
{
//repo as a singleton
ShoppingRepository shoppingRepo = ShoppingRepository.getInstance();
public Dictionary<string,List<Item>> GetShoppingItems()
{
//(1a) Get all shopping items. Can be of type drinks, stationary and any types that has been stored.
}
public HttpResponseMessage GetItems(string type)
{
//(2a Get shopping items of specific type. For example retrieve all drinks that is to be purchased.
}
public HttpResponseMessage GetItem(string type, string name)
{
//(3a) Get a specific shopping item of specific type given its name. For example retrieve a drink of name pepsi
}
public HttpResponseMessage GetItem(string type, int id)
{
//(4a) Get a specific shopping item of specific type given its id. For example retrieve a drink of id 1
}
public HttpResponseMessage PostItem(string type,List<Item> items)
{
//(5a) Add items to the shopping list. For example add a pepsi of type drinks.
}
public HttpResponseMessage Delete(string type,int id)
{
//(6a) Delete an item of a praticular type by its id.
}
public HttpResponseMessage Put(string type,int id, Item item)
{
//(7a) Update an item of a particular type given its id.
}
}
}

# Spring Boot "Retail Manager" Project
This is a simple Java / Gradle / Spring Boot application that can be used to develop a working prototype which satisfies
a Retail Manager that wanting to keep track of their shops.
# About the Service
The service is for retail manager to keep track of their shops, does a RESTful POST to /shops with a JSON of shopName, shopAddress.number and
shopAddress.postCode
to the Shops API (microservice) where shops are stored in memory. Permanent persistence of the data is not required.
The application can be used by multiple users at a time (no login functionality is required). Shops are identified by their unique names.
If user A adds a shop that was already added by user B, the service should replace previous version and REST response to user A should contain
information about the version that was replaced. If two users submit a shop at the same time, exactly one of them should get
information about replacing another version of the shop. Whenever a shop is added the service calls the Google Maps API.
The Google Maps API responds with the longitude and latitude, which allows the shop data to be updates with longitude and latitude.
A customer, using their geolocation on their phone, wants to find the store that is closest to them.
The Shops API will have the customerís longitude and latitude, but also the longitude and latitude of each shop to do the calculation.
The customer does a RESTful GET to the Shops API, providing their current longitude and latitude (e.g. URL request params), and gets back the address,
longitude and latitude of the shop nearest to them.
# How to Run
This application is packaged as a jar. You run it using the ```java -jar``` command.
* Clone this repository
* Make sure you are using JDK 1.8 and Gradle 3.x
* You can build the project and run the tests by running ```gradle build```
* Once successfully built, you can run the service by below commands :
java -jar <path>\retail-manager\build\libs\retail-manager-1.0.jar
OR
gradle run
Once the application runs you should see something like this
````````
2017-06-25 23:18:12.384 INFO 11324 --- [ main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 8080 (http)

# About Spring Boot
Spring Boot is an "opinionated" application bootstrapping framework that makes it easy to create new RESTful services (among other types of applications).
It provides many of the usual Spring facilities that can be configured easily usually without any XML.
In addition to easy set up of Spring Controllers, Spring Data, etc. Spring Boot comes with the Actuator module that gives the application
the following endpoints helpful in monitoring and operating the service: | 0e5bf2afaa790381fbf9f5a944a43a5ecb35a9cc | [

# Lonely Planet Front End Code Test
Welcome to the Lonely Planet coding test for front end developers wishing to join our team.
All you need to do is fork this repository, make your changes, and then submit a pull request which we will then review.
## Build a lightbox
We want to see your front-end skills and how you approach a problem with a specific set of requirements.
It has been started for you, but implementation details are up to you.
### Technical Requirements
The Lightbox should support the following:
- Be able to create a lightbox instance
- Common ways to close the lightbox (close button and ESC key).
- Fetching remote content.
- Rendering the content in the page.
- When the lightbox is open, the page behind it should not scroll.
#### Optional
- Build the component w/ React
- CSS animations/transitions for opening effects.
- Write in ES6 and transpile to ES5.
- Turn your lightbox into a jQuery plugin.
- Use jshint/jslint to analyze your code.
- Automate your workflow using tools like Webpack, Grunt or Gulp.
- Use Sass and a CSS autoprefixer.
- Add unit tests.

shellscript commands
====================
Protocol of shellscript commands
--------------------------------
All shellscript commands share properties, receive input and return output and
error codes in the same way. This same way is described in the **protocol** of
shellscript commands - every shellscript command has to conform to this it. The
protocol is designed to integrate other system commands seamless with
*shellscript* commands
1. Every command is a Python class.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2. Every command constructor excepts the arguments *out*, *err* and *outerr*.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Those arguments must either be commands, file objects, lists or a
*shellscript.dev* enumeration value. If *outerr* is set, this overrides
settings for *out* and *err*.
3. A command constructor can accept further arguments.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A command can accept further arguments specific to the command.
4. Every command instance is a generator that yields strings.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Per default the command generator exhausts itself once on initialization.
This behaviour can be altered by passing a value of *shellscript.dev.iter* to
*out*, *err* or *outerr*.
One string represents one line. Line breaks are not included in the strings.
5. Every string yielded by a command is an instance of *OutString* or *ErrString*.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This makes it possible to differentiate between *stdout* and *stderr* output.
6. A command must not raise an exception.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
An error is indicated by the commands return code. Error messages are given via
yielded strings that are of the type *ErrString*.
7. Every command instance has a *ret* attribute.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This attribute holds the return code of the command instance after its generator
is exhausted.
8. On error, every command generator must yield an *ErrString*.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is necessary to diagnose error causes.
Design
------
1. Every command must be importable by the *shellscript* module.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2. Command names must be as short as possible.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If possible command names should match names of corresponding POSIX shell
commands.

WebServiceTestHarness
=====================
Web Service Test Harness
This tool serves a very simple purpose of being able to produce web service
endpoints, based on very minimal config.
These endpoints can be used for testing purposes, when the real service may
not be available.
The code is WIP and will be updated as and when I find time.
If you would like to know more about this tool, please do drop the devs a note.
we are more than happy to help.

note that up to BBj 17, the BBjAPI().getJDBCConnection could not be used with basiscomponents:
```
if rev<"REV 17.10" then
url! = "jdbc:basis:localhost?DATABASE=ChileCompany&SSL=false"
con! = java.sql.DriverManager.getConnection(url!, "admin", "admin123")
else
bc! = new SqlQueryBC(BBjAPI().getJDBCConnection(db$))
fi
```
That's all we need to get a result set that works with the grid:
```
rs! = bc!.retrieve("SELECT * FROM "+tbl$)
```
...and set it as data:
```
grid!.setData(rs!)
```
```
fi
return
```
this is toggling the "fit to grid" functionality in the widget:
```
toggleFitToGrid:
declare auto BBjToolButtonPushEvent toogle_ev!
toggle_ev! = BBjAPI().getLastEvent()
if btn_fit!.isSelected() then
grid!.setFitToGrid(1)
else
grid!.setFitToGrid(0)
fi
return
```
Hidden Easter Egg: get the Console in the Java FX WebView:
```
onWinKeypress:
declare auto BBjKeypressEvent key_ev!
key_ev! = BBjAPI().getLastEvent()
if key_ev!.getKeyCode() = 342 then
grid!.showDeveloperConsole()
fi

<file_sep># JumpIn-iOS
The idea is very simple : motive people to do more exercises.
In order to motivate them, we decide to mixt sport but also fun.
To do this, the user have to make some jumps and then, according to how much jumps the user have done and altitude, the user can have different way of playing our game.
For example: The more he/she did jumps, the more he/she will have jumps to the game.
We decide to mix 2 parts : Game and Sport in order to motivate users as much as possible.

<file_sep># Parallel Programming Homeworks
This repository has all homeworks I have written in C++ in the parallel programming course of NTHU.
## Dependencies
Some programs require extra dependencies during linking. I concluded the dependencies those programs need in the following table:
| Homework Name | Dependencies |
| :------------- | :------------- |
| HW 2 - Roller Coaster Problem | pthread |
| HW 2 - N-body Problem - Pthread Implementation | pthread, X-Window |

For Splash, by Burak
## Overview
You can translate strings or arrays. String Example:
```php
// Create a driver that provides translations (see also PdoDriver for database functionality)
$driver = ArrayDriver::createFromArray([
['domain' => 'cust1', 'locale' => 'en', 'key' => 'greeting', 'content' => 'Hello'],
['domain' => 'cust1', 'locale' => 'es', 'key' => 'greeting', 'content' => 'Hola']
]);
$enTranslator = new Translator($driver);
$enTranslator->setLocale('en')->setDomain('cust1');
$inEnglish = $enTranslator->translateString("__{{greeting}}, my friend!");
// $inEnglish === 'Hello, my friend!'
$esTranslator = new Translator($driver);
$esTranslator->setLocale('es')->setDomain('cust1');
$inSpanish = $esTranslator->translateString("__{{greeting}}, my friend!");
// $inSpanish === 'Hola, my friend!'
// Translation tags can also have defaults if the key or language isn't found:
$deTranslator = new Translator($db);
$deTranslator->setLocale('de')->setDomain('cust1');
$withDefault = $deTranslator->translateString("__{{greeting, 'Greetings'}}, my friend!");
// $withDefault === 'Greetings, my friend!'
```
You can also recursively translate PHP arrays:
```php
$driver = ArrayDriver::createFromArray([
['locale' => 'en', 'key' => 'greeting', 'content' => 'Hello'],
['locale' => 'es', 'key' => 'greeting', 'content' => 'Hola']
]);
$translator = new Translator($driver);
$translated = $translator->setLocale('en')->translateArray([
"data" => [
"items" => [
[
"content" => [
"tagName" => "h1",
"value" => "__{{greeting, 'Greetings'}}"
]
]
]
]
]);
// $translated['data']['items'][0]['content']['value'] === "Hello"
```
## Translations and Template Tags
Translations (modeled by the `Translation` class) have four properties: a locale, a key, a domain, and content. The locale is a custom string (i.e., it does not need to be an ISO locale code) that represents the language, dialect, or flavor that you wish to translate to. The domain is another custom string that helps you distinguish translation catalogs by (for example) a customer ID or other application domain. For example, in a multi-tentant SaaS application, the domain might represent a customer ID. The key of a translation refers to the template tag that should be used to represent it, and the translation content is what the key will be replaced with.
Template tags are intended to appear in strings with the format `__{{key, "Default text"}}`. The default text is optional and can be wrapped in either single quotes or double quotes. The key is required. Unlike other translation systems, the domain is not part of the key in the template tag. Therefore, a tag like `__{{greeting}}` could have a corresponding translation of "Hello, Splash Customer" or "Hello, Android User", depending on the domain set on the translator.
## Installation
First, `composer require` this library.
If you wish to store translations in your database, you must create the `translations` table with the appropriate columns. If you are already using the `phinx` migration library, you can copy the phinx migration from the `dist/migrations` folder in this repo. If you are using another migration library, create a database table called `translations` with the following columns:
- key; varchar or text, not null
- locale; varchar or text, not null (if you know you're exclusively using ISO locale codes you can make this field varchar(5))
- domain; varchar or text, nullable
- content; text, not null
In your application you will need to at very least instantiate the Translator class and attach a driver to use for translation lookups.
## Connecting to a Database
Instantiate the Translator class with an instance of `PdoDriver` instead of `ArrayDriver`.
You will need a table called 'translations' with the text fields 'key', 'locale', 'domain', and 'content'.
It is a good idea to index on (key,locale,domain). There is an example Phinx migration in the `dist/migrations` folder.
```php
$pdo = new \PDO('mysql::.....', 'user', 'pass');
$driver = new PdoDriver($pdo);
$translator = new Translator($driver);
```
You can manage the translations in the database by interacting with the driver directly:
```php
$pdo = new \PDO('mysql::.....', 'user', 'pass');
$driver = new PdoDriver($pdo);
$driver->upsertTranslation('en', 'greeting', 'customer1', 'Hello');
$driver->deleteTranslation('en', 'greeting', 'customer1');
$driver->createTranslation('en', 'greeting', 'customer1', 'Hello');
$driver->updateTranslation('en', 'greeting', 'customer1', 'Hi');
```
## Singleton Instance
The Translator class provides a singleton/instance manager so that you can use Translator instances globally.
Set up:
```php
Translator::instance()->setDriver(new PdoDriver(new \PDO( ... )));
```
Use elsewhere:
```php
Translator::instance()->setLocale('en')->translateString('__{{name_tag}}');
```
You can also manage multiple, named instances:
```php
Translator::instance()->setDriver(new PdoDriver(new \PDO( ... )));
Translator::instance('temp')->setDriver(ArrayDriver::createFromArray( ... ));
Translator::instance('temp')->setLocale('en')->transArray(...);
```
## Using Custom Drivers
If you need to connect to a translation source that neither ArrayDriver nor PdoDriver can manage, you can create your own.
Simply implement the DriverInterface class in a custom class of your own and use that.
```php
class MyCustomDriver implements DriverInterface {
public function __construct($someCustomResource) { ... }
public function findTranslation($locale, $key, $domain = null) { ... }
public function findTranslations($locale, $keys, $domain = null) { ... }
public function updateTranslation($locale, $key, $domain, $content) { ... }
public function createTranslation($locale, $key, $domain, $content) { ... }
public function upsertTranslation($locale, $key, $domain, $content) { ... }
public function deleteTranslation($locale, $key, $domain = null) { ... }
}
$myCustomResource = new CustomResource(...);
$translator = new Translator(new MyCustomDriver($myCustomResource));
```
## Using Custom Parsers
This library is shipped with a `StringParser` and an `ArrayParser`, with translation methods aliased by `translateString` and `translateArray`. However you can create a custom Parser class to deal with other types of inputs.
Create a class that implements the ParserInterface (and potentially extends AbstractParser) and send an instance of it to `translateCustom`:
```php
class MyCustomParser extends AbstractParser implements ParserInterface {
public function parse() {
// Must return an array of Translatable objects
}
public function replace($translations) {
// Must replace the Translatables in the input with the $translations given, and return the translated output
}
}
```
You can then use it like so:
```php
$translator = new Translator($driver);
$output = $translator->translateCustom($input, new MyCustomParser());
```
## Using a Missing Translation Handler
This library provides a mechanism for alerting you when a translation key with no matching translation is found. This is helpful for putting together a list of translations that still need to be written.
The LogFileHandler accepts a PHP file resource and will write TSV content to it. You should open a file with append mode to append to the log.
```php
$logFile = fopen($filePath, 'a');
$handler = new LogFileHandler($logFile);
$translator->setHandler($handler);
// Missing translation keys will get logged to your $logFile here:
$translator->translateString(...);
```
You can also create a custom handler (to, for instance, log missing translations to a DB, slack, elasticsearch, etc). Simply implement the HandlerInterface.
## Running the tests
```
$ composer install
$ vendor/bin/phpunit tests/
```

*
* This class allows you to load a translations catalog in-memory, without using a database datastore.
* There are several ways to instantiate this driver, depending on your needs.
*
* Adding translations one at a time:
*
* ```php
* $driver = new ArrayDriver();
*
* $driver->createTranslation($locale, $key, $domain, $content);
* $driver->createTranslation($locale, $key, $domain, $content);
* // etc...

*
* You can add translations after the Translator has been instantiated:
*
* ```php
* $translator = new Translator(new ArrayDriver());
*
* $translator->getDriver()->createTranslation( ... );
* ```
*
* You can generate Translation instances and use setTranslations:
*
* ```
* $driver = new ArrayDriver();
*
* $translations = [
* new Translation($locale, $key, $content, $domain),
* new Translation($locale, $key, $content, $domain),
* new Translation($locale, $key, $content, $domain)
* ];
*
* $driver->setTranslations($translations);
* ```
*
* Or you can use the static createFromArray method:
*
* ```php
*
* $translator = new Translator(ArrayDriver::createFromArray([
* ['locale' => 'en', 'key' => 'foo', 'content' => 'bar', 'domain' => 'cust1'],
* ['locale' => 'en', 'key' => 'foo', 'content' => 'bar'],
* ['locale' => 'en', 'key' => 'foo', 'content' => 'bar'],
* // ... etc

# Automate managment of Kafka topics on the platform
This recipe will show how automate the management of Kafka topics using the jikkou tool, which is part of the platform.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services KAFKA,AKHQ,JIKKOU -s trivadis/platys-modern-data-platform -w 1.14.0
```
Now generate and start the platform
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Automate initial Kafka topic creation
In this recipe we will create to topics
* `topic-1` - with 8 paritions, replication-factor 3 and min.insync.replicas = 2
* `topic-2` - with 1 partition, replication-factor 3 as a log-compacted topic
In the `scripts/jikkou` folder, create a file named `topic-specs.yml` and add the following content
```yml
version: 1
specs:
topics:
- name: '{{ labels.topic.prefix | default('') }}topic-1'
partitions: 8
replication_factor: 3
configs:
min.insync.replicas: 2
- name: '{{ labels.topic.prefix | default('') }}topic-2'
partitions: 1
replication_factor: 3
configs:
cleanup.policy: compact
```
With the file in place, execute once again
```bash
docker-compose up -d
```
To see what Jikkou has done you can visit the log file of the `jikkou` service:
```bash
docker logs -f jikkou
```
you should see an output similar to the one below
```bash
20:34:59.775 [kafka-admin-client-thread | adminclient-1] WARN o.apache.kafka.clients.NetworkClient - [AdminClient clientId=adminclient-1] Connection to node -1 (kafka-1/172.18.0.8:19092) could not be established. Broker may not be available.
Can't read specification from file '/jikkou/topic-specs.yml': /jikkou/topic-specs.yml (No such file or directory)
TASK [CREATE] Create a new topic topic-2 (partitions=1, replicas=3) - CHANGED ***************************
TASK [CREATE] Create a new topic topic-1 (partitions=8, replicas=3) - CHANGED ***************************
EXECUTION in 2s 884ms
ok : 0, created : 2, altered : 0, deleted : 0 failed : 0
```
The first two lines are from the initial startup, where there was not yet a file in the folder. The last 3 lines show that the two new topics have been created.
The topic creation would also work if done initially when first starting the platform.
## Add a new and alter an existing Kafka topic
Edit the file `scripts/jikkou/topic-specs.yml` file and add a new topic `topic-3` and change the data retention of `topic-1` to unlimited (`-1`):
```yml
version: 1
specs:
topics:
- name: '{{ labels.topic.prefix | default('') }}topic-1'
partitions: 8
replication_factor: 3
configs:
min.insync.replicas: 2
retention.ms: -1
- name: '{{ labels.topic.prefix | default('') }}topic-2'
partitions: 1
replication_factor: 3
configs:
cleanup.policy: compact
- name: '{{ labels.topic.prefix | default('') }}topic-3'
partitions: 8
replication_factor: 3
```
Now perform again
```
docker-compose up -d
```
and visit the log. You should see the following additional lines
```bash
TASK [CREATE] Create a new topic topic-3 (partitions=8, replicas=3) - CHANGED ***************************
TASK [ALTER] Alter topic topic-1 - CHANGED *************************************************************
TASK [NONE] Unchanged topic topic-2 - OK ********************************************************
EXECUTION in 2s 371ms
ok : 1, created : 1, altered : 1, deleted : 0 failed : 0
```
## Set the label `topic.prefix`
For the names of the topics in the `topic-specs.yml`, we have used the label `topic.prefix` to specify a prefix for the topic names. So far the prefix is empty, as we have not yet specified it.
We can do that by adding it to the `JIKKOU_set_labels` property.
Edit the `config.yml` and add te follwing line right after `JIKKOU_enable: true`:
```bash
JIKKOU_set_labels: 'topic.prefix=dev-'
```
Regenerate the platform and again run `docker-compose`
```bash
platys gen
docker-compose up -d
```
View the log
```bash
docker logs -f jikkou
```
and see that the old topics have been removed and the new ones with the prefix `dev-` were created.
```bash
TASK [CREATE] Create a new topic dev-topic-3 (partitions=8, replicas=3) - CHANGED ***********************
TASK [DELETE] Delete topic topic-1 - CHANGED ***********************************************************
TASK [CREATE] Create a new topic dev-topic-2 (partitions=1, replicas=3) - CHANGED ***********************
TASK [DELETE] Delete topic topic-2 - CHANGED ***********************************************************
TASK [CREATE] Create a new topic dev-topic-1 (partitions=8, replicas=3) - CHANGED ***********************
TASK [DELETE] Delete topic topic-3 - CHANGED ***********************************************************
EXECUTION in 3s 51ms
ok : 0, created : 3, altered : 0, deleted : 3 failed : 0

# Spark with Delta Lake
This recipe will show how to use a Spark cluster together with the [Delta Lake](http://delta.io) storage framework. We will be using the Python and SQL API.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services SPARK,ZEPPELIN,MINIO,AWSCLI,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.16.0
```
Before we can generate the platform, we need to extend the `config.yml`:
Specify the table format to use as Delta.
```
SPARK_table_format_type: 'delta'
```
Platys automatically makes sure that the right version according to [the compatibility table in the Delta Lake documentation](https://docs.delta.io/latest/releases.html) is used.
Now set an environment variable to the home folder of the dataplatform and generate and then start the data platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Prepare some data in Object storage
Create the flight bucket:
```bash
docker exec -ti awscli s3cmd mb s3://flight-bucket
```
Now upload the airports to the bucket
```bash
docker exec -ti awscli s3cmd put /data-transfer/flight-data/airports.csv s3://flight-bucket/raw/airports/airports.csv
```
## Working with Delta Lake from Zeppelin
Navigate to Zeppelin <http://dataplatform:28080> and login as user `admin` with password `<PASSWORD>!`.
Create a new notebook and add and execute the following commands:
Import necessary modules
```python
%pyspark
from delta.tables import *
from pyspark.sql.types import *
```
Load the raw Airport data in the CSV format into a data frame
```python
%pyspark
airportsRawDF = spark.read.csv("s3a://flight-bucket/raw/airports",
sep=",", inferSchema="true", header="true")
airportsRawDF.show(5)
```
create a new delta table
```python
%pyspark
deltaTableDest = "s3a://flight-bucket/delta/airports"
airportsRawDF.write.format("delta").save(deltaTableDest)
```
Use the `CREATE TABLE` to register the delta table in SQL
```sql
%sql
CREATE TABLE airports_t
USING DELTA
LOCATION 's3a://flight-bucket/delta/airports'
```
Use the delta table in a SQL statement
```sql
%sql

The Gremlin Console serves a variety of use cases that can meet the needs of different types of Gremlin users. This tutorial explores the features of the Gremlin Console through a number of these different use cases to hopefully inspire you to new levels of usage. While a use case may not fit your needs, you may well find it worthwhile to read, as it is possible that a "feature" will be discussed that may be useful to you.

```bash
platys init --enable-services GREMLIN_CONSOLE
platys gen
```
## How to use it?
### Using the Gremlin Console
To start a gremlin console
```bash
docker exec -ti gremlin-console ./bin/gremlin.sh
```
and then connect to
```groovy
:remote connect tinkerpop.server conf/remote.yaml
g = traversal().withRemote('conf/remote-graph.properties')
g.addV('demigod').property('name', 'hercules').iterate()
g.V()
```
### Initialise JanusGraph
When the container is started it will execute files with the extension `.groovy` that are found in `./init/janusgraph/` with the Gremlin Console. These scripts are only executed after the JanusGraph Server instance was started. So, they can connect to it and execute Gremlin traversals.
For example, to add a vertex to the graph, create a file `./init/janusgraph/add-vertex.groovy` with the following content
```groovy
g = traversal().withRemote('conf/remote-graph.properties')
g.addV('demigod').property('name', 'hercules').iterate()

In this workshop we will learn how to produce and consume messages using the [Kafka .NET API](https://docs.confluent.io/clients-confluent-kafka-dotnet/current/overview.html) using Avro for serialising and deserialising messages.
We assume that .NET Core is installed on your client as well as Visual Code with the C# extension (ms-dotnettools.csharp) enabled. We will use the .NET CLI (`dotnet`) for creating projects and running the code.
## Create the project structure
We will create two projects, one acting as the producer to Kafka and the other one as the consumer from Kafka.
First create the workspace folder, which will hold our projects and navigate into it.
```bash
mkdir kafka-dotnet-avro-workshop
cd kafka-dotnet-avro-workshop
```
Now let's create the producer project
```bash
dotnet new console -o producer
```
Now start Visual Code, on Linux if installed using the [following documentation](https://code.visualstudio.com/docs/setup/linux), then it can be started with `code`.
```bash
code
```
We are now ready to add code to the classes which have been created with the `dotnet new` command.
But before we do that, let's create the topic we will use to produce to and to consume from.
### Creating the necessary Kafka Topic
We will use the topic `test-dotnet-avro-topic` in the Producer and Consumer code below. Because `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
Connect to the `kafka-1` container
```
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```
kafka-topics --create \
--replication-factor 3 \
--partitions 8 \
--topic test-dotnet-avro-topic \
--bootstrap-server kafka-1:19092,kafka-2:19093
```
Cross check that the topic has been created.
```
kafka-topics --list --bootstrap-server kafka-1:19092
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing a **Kafka Producer**.
## Install the Avro CLI
To use the [Avro CLI](https://www.nuget.org/packages/Apache.Avro.Tools/), you need to have the .NET SDK 5.0 (6.0 is not supported)
To Install it on CentOS, perform
```bash
sudo yum install dotnet-sdk-5.0
```
Now you can install the Avro CLI
```bash
dotnet tool install --global Apache.Avro.Tools --version 1.11.0
```
## Create the Avro Schema
First create a new file `Notification.avsc` and add the following Avro schema
```JSON
{
"type" : "record",
"namespace" : "com.trivadis.kafkaws.avro.v1",
"name" : "Notification",
"description" : "A simple Notification Event message",
"fields" : [
{ "type" : ["long", "null"],
"name" : "id"
},
{ "type" : ["string", "null"],
"name" : "message"
}
]
}
```
## Generate a C# class for the schema
Now you can generate the corresponding C# class using
```bash
avrogen -s Notification.avsc .
```
The following class will be generated
```csharp
// ------------------------------------------------------------------------------
// <auto-generated>
// Generated by avrogen, version 1.11.0.0
// Changes to this file may cause incorrect behavior and will be lost if code
// is regenerated
// </auto-generated>
// ------------------------------------------------------------------------------
namespace com.trivadis.kafkaws.avro.v1
{
using System;
using System.Collections.Generic;
using System.Text;
using Avro;
using Avro.Specific;
public partial class Notification : ISpecificRecord
{
public static Schema _SCHEMA = Avro.Schema.Parse("{\"type\":\"record\",\"name\":\"Notification\",\"namespace\":\"com.trivadis.kafkaws.avro.v1\"" +
",\"fields\":[{\"name\":\"id\",\"type\":[\"long\",\"null\"]},{\"name\":\"message\",\"type\":[\"strin" +
"g\",\"null\"]}],\"description\":\"A simple Notification Event message\"}");
private System.Nullable<System.Int64> _id;
private string _message;
public virtual Schema Schema
{
get
{
return Notification._SCHEMA;
}
}
public System.Nullable<System.Int64> id
{
get
{
return this._id;
}
set
{
this._id = value;
}
}
public string message
{
get
{
return this._message;
}
set
{
this._message = value;
}
}
public virtual object Get(int fieldPos)
{
switch (fieldPos)
{
case 0: return this.id;
case 1: return this.message;
default: throw new AvroRuntimeException("Bad index " + fieldPos + " in Get()");
};
}
public virtual void Put(int fieldPos, object fieldValue)
{
switch (fieldPos)
{
case 0: this.id = (System.Nullable<System.Int64>)fieldValue; break;
case 1: this.message = (System.String)fieldValue; break;
default: throw new AvroRuntimeException("Bad index " + fieldPos + " in Put()");
};
}
}
}
```
## Create a Kafka Producer
To communicate with Kafka, we need to use the [**confluent-kafka-dotnet**](https://docs.confluent.io/clients-confluent-kafka-dotnet/current/overview.html) .NET library].
The reference the library from the .NET Core project, execute the following command from within the `kafka-dotnet-workspace` folder.
```
dotnet add producer package Confluent.Kafka
dotnet add producer package Confluent.SchemaRegistry.Serdes.Avro --version 1.8.2
```
The following reference will be added to project metadata
```
<Project Sdk="Microsoft.NET.Sdk">
...
<ItemGroup>
<PackageReference Include="Confluent.Kafka" Version="1.8.2" />
<PackageReference Include="Confluent.SchemaRegistry.Serdes.Avro" Version="1.8.2" />
</ItemGroup>
</Project>
```
Now let's add the code for producing messages to the Kafka topic. Navigate to the `Program.cs` C# class in the `producer` project and rename it to `KafkaProducer.cs` and then open it in the editor.
Add the following directives on the top with the class and the following two constants for the Broker List and the Topic name:
```csharp
using System.Threading;
using Confluent.Kafka;
class KafkaProducer
{
const string brokerList = "dataplatform:9092,dataplatform:9093";
const string topicName = "test-dotnet-topic";
}
```
Add the following main method to the class:
```csharp
static void Main(string[] args)
{
long startTime = DateTimeOffset.Now.ToUnixTimeMilliseconds();
if (args.Length == 0)
{
runProducerASync(100, 10, 0);
}
else
{
runProducerASync(int.Parse(args[0]), int.Parse(args[1]), int.Parse(args[2]));
}
long endTime = DateTimeOffset.Now.ToUnixTimeMilliseconds();
Console.WriteLine("Producing all records took : " + (endTime - startTime) + " ms = (" + (endTime - startTime) / 1000 + " sec)" );
}
// place the runProducerXXXX methods below
```
The `Main()` method accepts 3 parameters, the number of messages to produce, the time in ms to wait in-between sending each message and the ID of the producer.
Add the following additional method for implementing the Kafka producer. We are using the asynchronous produce option with the `ProduceAsync`
```csharp
static void runProducerASync(int totalMessages, int waitMsInBetween, int id)
{
var config = new ProducerConfig { BootstrapServers = brokerList };
var schemaRegistryConfig = new SchemaRegistryConfig
{
// Note: you can specify more than one schema registry url using the
// schema.registry.url property for redundancy (comma separated list).
// The property name is not plural to follow the convention set by
// the Java implementation.
Url = schemaRegistryUrl
};
var avroSerializerConfig = new AvroSerializerConfig
{
// optional Avro serializer properties:
BufferBytes = 100
};
using (var schemaRegistry = new CachedSchemaRegistryClient(schemaRegistryConfig))
// Create the Kafka Producer
using (var producer = new ProducerBuilder<Null, Notification>(config)
.SetValueSerializer(new AvroSerializer<Notification>(schemaRegistry, avroSerializerConfig))
.Build())
{
for (int index = 0; index < totalMessages; index++)
{
long time = DateTimeOffset.Now.ToUnixTimeMilliseconds();
// Construct the message value
Notification value = new Notification { id = id, message = "[" + index + ":" + id + "] Hello Kafka " + DateTimeOffset.Now };
// send the message to Kafka
var deliveryReport = producer.ProduceAsync(topicName, new Message<Null, Notification> { Value = value });
deliveryReport.ContinueWith(task =>
{
if (task.IsFaulted)
{
}
else
{
Console.WriteLine($"[{id}] sent record (key={task.Result.Key} value={task.Result.Value}) meta (partition={task.Result.TopicPartition.Partition}, offset={task.Result.TopicPartitionOffset.Offset}, time={task.Result.Timestamp.UnixTimestampMs})");
}
});
Thread.Sleep(waitMsInBetween);
}
producer.Flush(TimeSpan.FromSeconds(10));
}
}
```
Before starting the producer, in an additional terminal, let's use `kcat` or `kafka-avro-console-consumer` to consume the messages from the topic `test-dotnet-topic`.
```
kafkacat -b $PUBLIC_IP -t test-java-avro-topic
```
Now run it using the `mvn exec:java` command. It will generate 1000 messages, waiting 10ms in-between sending each message and use 0 for the ID.
```
mvn exec:java@producer -Dexec.args="1000 100 0"
```
You can see that kafkacat shows some special, non-printable characters. This is due to the Avro format. If you want to display the Avro, you can use the `kafka-avro-console-consumer` CLI, which is part of the Schema Registry.
So let's connect to the schema registry container:
```
docker exec -ti schema-registry-1 bash
```
And then invoke the `kafka-avro-console-consumer` similar to the "normal" consumer seen so far.
```
kafka-avro-console-consumer --bootstrap-server kafka-1:19092 --topic test-java-avro-topic
```
You should see an output similar to the one below.
```
...
[2018-07-11 21:32:43,155] INFO [Consumer clientId=consumer-1, groupId=console-consumer-88150] Resetting offset for partition test-java-avro-topic-6 to offset 0. (org.apache.kafka.clients.consumer.internals.Fetcher)
{"id":{"long":0},"message":{"string":"Hello Kafka 0"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 3"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 1"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 2"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 4"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 5"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 6"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 9"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 7"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 10"}}
{"id":{"long":0},"message":{"string":"Hello Kafka 8"}}
...
```
if you want to consume with `kcat` you need to specify the serialisation format `-s` and the address of the schema registry `-r`:
```
kcat -b kafka-1 -t test-java-avro-topic -s value=avro -r http://schema-registry-1:8081
```
**Note**: For Avro support your kafkacat version needs to be `1.6' or later.
## View the Schema in the Registry
The Avro Serializer and Deserializer automatically register the Avro schema, if it is not already in the registry.
The Streamingplatform also contains a tool made by a company called Landoop which allows us to see what's in the registry.
In a browser, navigate to <http://dataplatform:28039> and you should see the home page of the Schema Registry UI.
If you click on the schema to the left, you can view the details of the schema. You can see that version v1 has been assigned automatically.

# Apicurio Registry with SQL Storage (PostgreSQL)
This recipe will show how to use the Apicurio Registry as a Confluent-compliant Schema Registry.
## Initialise data platform
First [initialise a platys-supported data platform](../../../documentation/getting-started) with the following services enabled
```
platys init --enable-services KAFKA,SCHEMA_REGISTRY,POSTGRESQL,KAFKA_UI,ADMINER -s trivadis/platys-modern-data-platform -w 1.14.0
```
edit the `config.yml` and add the followin properties right after `SCHEMA_REGISTRY_enable: true`:
```yaml
SCHEMA_REGISTRY_flavour: apicurio
APICURIO_SCHEMA_REGISTRY_storage: sql
```
By default, Apicurio Registry is configured to use Postgresql with a database of `apicuriodb`, a user of `apicurio` with a password of `<PASSWORD>!`.
Therefore we need to configure PosgreSQL accordingly by adding the following properties after the `POSTGRESQL_enable: true`:
```yaml
POSTGRESQL_multiple_databases: 'apicuriodb'
POSTGRESQL_multiple_users: 'apicurio'
POSTGRESQL_multiple_passwords: '<PASSWORD>!'
```
Now start the platform
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Using Confluent Schema-Registry Compliant URL
The Apicurio Registry is available on port 8081. It offers a confluent-compliant REST interface available under this base URL:
```bash
http://dataplatform:8081/apis/ccompat/v6
```
## Register a schema using Kafka UI
Kafka UI has the option to view and edit a schema registry. It is configured using the confluent-compliant REST API of Apicurio Registry.
In a web browser, navigate to the Kafka UI: <http://192.168.142.129:28179>.
In the menu on the left, click on **Schema Registry**. Click **Create Schema** and add a schema using
* **Subject**: `test-value`
* **Schema**:
```json
{
"type" : "record",
"name" : "MyRecord",
"namespace" : "com.mycompany",

## Introduction
In this workshop we will learn the basics of working with Apache Kafka. Make sure that you have created the environment as described in [Preparing the Environment](../01-environment/README.md).
The main units of interest in Kafka are topics and messages. A topic is simply what you publish a message to, topics are a stream of messages.
In this workshop you will learn how to create topics, how to produce messages, how to consume messages and how to describe/view metadata in Apache Kafka.
## Working with built-in Command Line Utilities
### Connect to a Kafka Broker
The environment contains of a Kafka cluster with 3 brokers, all running on the Docker host of course. So it's of course not meant to really fault-tolerant but to demonstrate how to work with a Kafka cluster.
To work with Kafka you need the command line utilities. They are available on each broker.
The `kafka-topics` utility is used to create, alter, describe, and delete topics. The `kafka-console-producer` and `kafka-console-consumer` can be used to produce/consume messages to/from a Kafka topic.
So let's connect into one of the broker through a terminal window.
* If you have access through Guacamole, then right click on the dashboard and select **Open Terminal**.
* if you have a user and password, you can also use a browser-based terminal, by navigating to <http://localhost:3001> and then login with username and password.
In the terminal window run a `docker exec` command to start a shell in the `kafka-1` docker container
```bash
docker exec -ti kafka-1 bash
```
if we just execute the `kafka-topics` command without any options, a help page is shown
```bash
root@kafka-1:/# kafka-topics
Create, delete, describe, or change a topic.
Option Description
------ -----------
--alter Alter the number of partitions,
replica assignment, and/or
configuration for the topic.

describing topics, the action will
only execute if the topic exists.
--if-not-exists if set when creating topics, the
action will only execute if the
topic does not already exist.
--list List all available topics.
--partitions <Integer: # of partitions> The number of partitions for the topic

```
### List topics in Kafka
First, let's list the topics available on a given Kafka Cluster. For that we use the `kafka-topics` utility with the `--list` option.
```
kafka-topics --list --bootstrap-server kafka-1:19092,kafka-2:19093
```
We can see that there are some technical topics, `_schemas` being the one, where the Confluent Schema Registry stores its schemas.
### Creating a topic in Kafka
Now let's create a new topic. For that we again use the **kafka-topics** utility but this time with the `--create` option. We will create a test topic with 6 partitions and replicated 2 times. The `--if-not-exists` option is handy to avoid errors, if a topic already exists.
```bash
kafka-topics --create \
--if-not-exists \
--bootstrap-server kafka-1:19092,kafka-2:19093 \
--topic test-topic \
--partitions 6 \
--replication-factor 2
```
Re-Run the command to list the topics. You should see the new topic you have just created.
### Describe a Topic
You can use the `--describe` option to
```bash
kafka-topics --describe --bootstrap-server kafka-1:19092,kafka-2:19093 --topic test-topic
```
```bash
Topic:test-topicPartitionCount:6ReplicationFactor:2Configs:
Topic: test-topicPartition: 0Leader: 3Replicas: 3,2Isr: 3,2
Topic: test-topicPartition: 1Leader: 1Replicas: 1,3Isr: 1,3
Topic: test-topicPartition: 2Leader: 2Replicas: 2,1Isr: 2,1
Topic: test-topicPartition: 3Leader: 3Replicas: 3,1Isr: 3,1
Topic: test-topicPartition: 4Leader: 1Replicas: 1,2Isr: 1,2
Topic: test-topicPartition: 5Leader: 2Replicas: 2,3Isr: 2,3
```
### Produce and Consume to Kafka topic with command line utility
Now let's see the topic in use. The most basic way to test it is through the command line. Kafka comes with two handy utilities `kafka-console-consumer` and `kafka-console-producer` to consume and produce messages through the command line.
In a new terminal window, first let's run the consumer on the topic `test-topic` we have created before
```bash
kafka-console-consumer --bootstrap-server kafka-1:19092,kafka-2:19093 \
--topic test-topic
```
After it is started, the consumer just waits for newly produced messages.
In an another terminal, again connect into `kafka-1` using a `docker exec`
```bash
docker exec -ti kafka-1 bash
```
and run the following command to start the producer.
```bash
kafka-console-producer --bootstrap-server kafka-1:19092,kafka-2:19093 --topic test-topic
```
By default, the console producer waits for **1000ms** before sending messages, if they are not larger than 16'384 bytes. The reason for that is as follows:
* the `linger.ms` parameter is set using the `--timeout` option on the command line which if not specified is **1000 ms**.
* the `batch.size` parameter is set using the `--max-partition-memory-bytes` option on the command line which if not specified is **16384**.
* **Note:** even if you specify `linger.ms` and `batch.size` using `--producer-property` or `--producer.config`, they will be always overwritten by the above "specific" options!
The console producer reads from stdin, and takes a bootstrap-server list (you should use it instead of the borker-list, which is deprecated). We specify 2 of the 3 brokers of the Data Platform.
On the `>` prompt enter a few messages, execute each single message by hitting the **Enter** key.<br>
```bash
>aaa
>bbb
>ccc
>ddd
>eee
```
You should see the messages being consumed by the consumer.
```bash
root@kafka-1:/# kafka-console-consumer --bootstrap-server kafka-1:19092,kafka-2:19093 --topic test-topic
aaa
bbb
ccc
ddd
eee
```
Messages arrive in the same order because you are just not able to enter them quick enough.
You can stop the consumer by hitting **Ctrl-C**. If you want to consume from the beginning of the log, use the `--from-beginning` option.
You can also echo a longer message and pipe it into the console producer, as he is reading the next message from the command line:
```bash
echo "This is my first message!" | kafka-console-producer \
--bootstrap-server kafka-1:19092,kafka-2:19093 \
--topic test-topic
```
And of course you can send messages inside a bash for loop:
```bash
for i in 1 2 3 4 5 6 7 8 9 10
do
echo "This is message $i"| kafka-console-producer \
--bootstrap-server kafka-1:19092,kafka-2:19093 \
--topic test-topic \
--batch-size 1 &
done
```
By ending the command in the loop with an & character, we run each command in the background and in parallel.
If you check the consumer, you can see that they are not in the same order as sent, because of the different partitions, and the messages being published in multiple partitions. We can force order by using a key when publishing the messages and always using the same value for the key.
### Working with Keyed Messages
A message produced to Kafka always consists of a key and a value, the value being necessary and representing the message/event payload. If a key is not specified, such as we did so far, then it is passed as a null value and Kafka distributes such messages in a round-robin fashion over the different partitions.
We can check that by re-consuming the messages we have created so far, specifying the option `--from-beginning` together with the option `print.key` and `key.separator` in the console consumer. For that stop the old consumer and restart it again using the following command
```bash
kafka-console-consumer --bootstrap-server kafka-1:19092,kafka-2:19093 \
--topic test-topic \
--property print.key=true \
--property key.separator=, \
--from-beginning
```
We can see that the keys are all `null` because so far we have only created the value part of the messages.
For producing messages also with a key, use the options `parse.key` and `key.separator`.
```bash
kafka-console-producer --bootstrap-server kafka-1:19092,kafka-2:19093 \
--topic test-topic \
--property parse.key=true \
--property key.separator=,
```
Enter your messages so that a key and messages are separated by a comma, i.e. `key1,value1`. Do that for a few messages and check that they are shown in the console consumers as key and value.
### Dropping a Kafka topic
A Kafka topic can be dropped using the `kafka-topics` utility with the `--delete` option.
```bash
kafka-topics --bootstrap-server kafka-1:19092,kafka-2:19093 --delete --topic test-topic
```
## Working with the `kcat` utility
[kcat](https://github.com/edenhill/kcat) is a command line utility that you can use to test and debug Apache Kafka deployments. You can use `kafkacat` to produce, consume, and list topic and partition information for Kafka. Described as “netcat for Kafka”, it is a swiss-army knife of tools for inspecting and creating data in Kafka.
It is similar to the `kafka-console-producer` and `kafka-console-consumer` you have learnt and used above, but much more powerful and also simpler to use.
`kcat` is an open-source utility, available at <hhttps://github.com/edenhill/kcat>. It is not part of the Confluent platform and also not part of the Data Platform we run in docker.
You can run `kcat` as a standalone utility on any **Linux** or **Mac** computer and remotely connect to a running Kafka cluster.
### Installing `kcat`
Officially `kcat` is either supported on **Linux** or **Mac OS-X**. There is no official support for **Windows** yet. There is a Docker image for `kcat` from Confluent as well.
We will show how to install it on **Ubunut** and **Mac OS-X**.
In all the workshops we will assume that `kcat` (used to be named `kafkacat` before version `1.7`) is installed locally on the Docker Host and that `dataplatform` alias has been added to `/etc/hosts`.
#### Ubuntu 20.04 or 22.04
You can install `kcat` directly on the Ubuntu environment. On Ubuntu 20.04 and 22.04 version 1.7 of `kcat` is not available and therefore you still have to install `kafkacat`.
First installhe Confluent public key, which is used to sign the packages in the APT repository:
```bash
wget -qO - https://packages.confluent.io/deb/5.2/archive.key | sudo apt-key add -
```
Add the repository to the `/etc/apt/sources.list`:
```bash
sudo add-apt-repository "deb [arch=amd64] https://packages.confluent.io/deb/5.2 stable main"
```
Run apt-get update and install the 2 dependencies as well as **kafkacat**
```bash
sudo apt-get update
sudo apt-get install librdkafka-dev libyajl-dev
sudo apt-get install kafkacat
```
You can define an alias, so that you can work with `kcat` even though you "only" have `kafkacat`:
```bash
alias kcat=kafkacat
```
let's see the version
```

```
#### Ubuntu 23.04
```bash
sudo apt-get install kcat

```
#### Mac OS-X
To install `kcat` on a Macbook, just run the following command:
```bash
brew install kcat
```
let's see the version
```bash
% kcat -V

```
#### Docker Container
There is also a Docker container which can be used to run `kcat`
```bash
docker run --tty --network kafka-workshop edenhill/kcat:1.7.1 kcat
```
By setting an alias, we can work with the dockerized version of `kcat` as it would be a local command. All further examples assume that this is the case.
```bash
alias kcat='docker run --tty --network kafka-workshop edenhill/kcat:1.7.0 kcat'
```
Check the [Running in Docker](https://github.com/edenhill/kcat#running-in-docker) to see more options for using `kcat` with Docker.
#### Windows
There is no official support to run `kcat` on Windows. You might try the following link to run it on Windows: <https://ci.appveyor.com/project/edenhill/kafkacat/builds/23675338/artifacts>.
An other option for Windows is to run it as a Docker container as shown above.
### Display `kcat` options
`kcat` has many options. If you just enter `kcat` without any options, all the options with a short description are shown on the console. Additionally kcat will show the version which is installed. This is currently **1.7.0** if installed on Mac and **1.6.0** if on Ubuntu.

With -l, only one file permitted.
Otherwise, the entire file contents will
be sent as one single message.
-X transactional.id=.. Enable transactions and send all
messages in a single transaction which
is committed when stdin is closed or the

$: match end-of-input (no more bytes remaining or a parse error is raised).
Not including this token skips any
remaining data after the pack-str is
exhausted.
avro - Avro-formatted with schema in Schema-Registry (requires -r)
E.g.: -s key=i -s value=avro - key is 32-bit integer, value is Avro.
or: -s avro - both key and value are Avro-serialized
-r <url> Schema registry URL (when avro deserializer is used with -s)
-D <delim> Delimiter to separate messages on output

Metadata options (-L):
-t <topic> Topic to query (optional)
Query options (-Q):
-t <t>:<p>:<ts> Get offset for topic <t>,
partition <p>, timestamp <ts>.
Timestamp is the number of milliseconds
since epoch UTC.
Requires broker >= 0.10.0.0 and librdkafka >= 0.9.3.

%T Message timestamp (milliseconds since epoch UTC)
%h Message headers (n=v CSV)
%t Topic
%p Partition
%o Message offset
\n \r \t Newlines, tab
\xXX \xNNN Any ASCII character
Example:
-f 'Topic %t [%p] at offset %o: key %k: %s\n'
JSON message envelope (on one line) when consuming with -J:
{ "topic": str, "partition": int, "offset": int,
"tstype": "create|logappend|unknown", "ts": int, // timestamp in milliseconds since epoch
"broker": int,
"headers": { "<name>": str, .. }, // optional
"key": str|json, "payload": str|json,
"key_error": str, "payload_error": str, //optional
"key_schema_id": int, "value_schema_id": int //optional
}
notes:
- key_error and payload_error are only included if deserialization fails.
- key_schema_id and value_schema_id are included for successfully deserialized Avro messages.
Consumer mode (writes messages to stdout):
kcat -b <broker> -t <topic> -p <partition>
or:
kcat -C -b ...
High-level KafkaConsumer mode:
kcat -b <broker> -G <group-id> topic1 top2 ^aregex\d+
Producer mode (reads messages from stdin):
... | kcat -b <broker> -t <topic> -p <partition>
or:
kcat -P -b ...
Metadata listing:
kcat -L -b <broker> [-t <topic>]
Query offset by timestamp:
kcat -Q -b broker -t <topic>:<partition>:<timestamp>
```
Now let's use it to Produce and Consume messages.
### Consuming messages using `kcat`
All the examples below are shown using `kcat`. If you are still on the older version (before `1.7` replace `kcat` with `kafkacat` or specify an alias as shown above).
**Note:** Replace `dataplatform` by `kafka-1:19092` if you are using the dockerized version of `kcat` in all of the samples below (i.e. `kafka-1:19092`).
The simplest way to consume a topic is just specifying the broker and the topic. By default all messages from the beginning of the topic will be shown.
```bash
kcat -b dataplatform -t test-topic
```
If you want to start at the end of the topic, i.e. only show new messages, add the `-o` option.
```bash
kcat -b dataplatform -t test-topic -o end
```
To show only the last message (one for each partition), set the `-o` option to `-1`. `-2` would show the last 2 messages.
```bash
kcat -b dataplatform -t test-topic -o -1
```
To show only the last message from exactly one partition, add the `-p` option
```bash
kcat -b dataplatform -t test-topic -p1 -o -1
```
You can use the `-f` option to format the output. Here we show the partition (`%p`) as well as key (`%k`) and value (`%s`):
```bash
kcat -b dataplatform -t test-topic -f 'Part-%p => %k:%s\n'
```
If there are keys which are Null, then you can use `-Z` to actually show NULL in the output:
```bash
kcat -b dataplatform -t test-topic -f 'Part-%p => %k:%s\n' -Z
```
There is also the option `-J` to have the output emitted as JSON.
```bash
kcat -b dataplatform -t test-topic -J
```
### Producing messages using `kcat`
Producing messages with `kcat` is as easy as consuming. Just add the `-P` option to switch to Producer mode.
```bash
kcat -b dataplatform -t test-topic -P
```
To produce with key, specify the delimiter to split key and message, using the `-K` option.
```bash
kcat -b dataplatform -t test-topic -P -K , -X topic.partitioner=murmur2_random
```
Find some more example on the [kcat GitHub project](https://github.com/edenhill/kcat) or in the [Confluent Documentation](https://docs.confluent.io/current/app-development/kafkacat-usage.html).
### Send "realistic" test messages to Kafka using Mockaroo and `kcat`
In his [blog article](https://rmoff.net/2018/05/10/quick-n-easy-population-of-realistic-test-data-into-kafka-with-mockaroo-and-kafkacat/) <NAME> shows an interesting and easy approach to send realistic mock data to Kafka. He is using [Mockaroo](https://mockaroo.com/), a free test data generator and API mocking tool, together with [kcat](https://github.com/edenhill/kcat) to produce mock messages.
Taking his example, you can send 10 orders to test-topic (it will not work if you use the dockerized version of `kcat`)
```bash

## Publishing a "real" data stream to Kafka
Next we will see a more realistic example using the [Streaming Synthetic Sales Data Generator](https://github.com/garystafford/streaming-sales-generator). It is available as a [Docker Image](https://hub.docker.com/repository/docker/trivadis/sales-data-generator).
We can use it to stream simulated sales data into Kafka topics. By no longer manually producing data, we can see unbounded data "in action".
First let's create the necessary 3 topics:
```bash
docker exec -ti kafka-1 kafka-topics --create --bootstrap-server kafka-1:19092 --topic demo.products --replication-factor 3 --partitions 6
docker exec -ti kafka-1 kafka-topics --create --bootstrap-server kafka-1:19092 --topic demo.purchases --replication-factor 3 --partitions 6
docker exec -ti kafka-1 kafka-topics --create --bootstrap-server kafka-1:19092 --topic demo.inventories --replication-factor 3 --partitions 6
```
The default configuration assumes that the container runs in the same network as the Kafka cluster, therefore we have to pass the name of the network when running the container.
```bash
docker network list
```
For the Kafka workshop environment, it should be `kafka-workshop`. If you are using the workshop with another dataplatform, then you have to adapt the `--network` option in following statement:
```bash
docker run -ti --network kafka-workshop trivadis/sales-data-generator:latest
```
Now use `kcat` to see the data streaming into the `demo.purchases` topic.
```bash
kcat -b dataplatform -t demo.purchases
```
You can also use the **Live Tail** option of **AKHQ** (see next section).
## Using AKHQ
[AKHQ](https://akhq.io/) is an open source Kafka GUI for Apache Kafka to manage topics, topics data, consumers group, schema registry, connect and more... It has been started as part of the **dataplatform** and can be reached on <http://dataplatform:28107/>.
By default you will end-up on the topics overview page
Navigate to **Nodes** in the menu on the left to see the Kafka cluster with its 3 brokers.
To see again the topics, click on **Topics** in the menu.
Currently there is only one topic shown, due to the default setting of hiding internal topics.
You can select **Show all topics** in the drop down to also view the internal topics, such as `__consumer_offsets`.
To view the data stored in a topic, click on the **magnifying glass** icon on the right side
and you should see the first page of messages of the topic
You can also view the live data arriving in a topic by navigating to **Live Tail** in the menu on the left. You might want to re-run the **Streaming Synthetic Sales Data Generator** seen before, if it is no longer running.
Select one or more topics you wish to see the live data streaming in
Click on the **magnifying glass** icon and the data will be shown as it arrives in the topic
If you want to empty a topic, then navigate to **Topics** in the menu, select a topic by clicking on the **magnifying glass** icon on the right side
and click **Empty Topic**.
AKHQ can also be used to
## Using CMAK (Cluster Manager for Apache Apache Kafka)
[CMAK](https://github.com/yahoo/CMAK), previously known as **Kafka Manager** is an open source tool created by Yahoo for managing a Kafka cluster. It has been started as part of the **dataplatform** and can be reached on <http://dataplatform:28104/>.
Navigate to the **Cluster** menu and click on the drop-down and select **Add Cluster**.
The **Add Cluster** details page should be displayed. Enter the following values into the edit fields / drop down windows:
* **Cluster Name**: Streaming Platform
* **Custer Zookeeper Hosts**: zookeeper-1:2181
* **Kafka Version**: 2.0.0
Select the **Enable JMX Polling**, **Poll consumer information**, **Filter out inactive consumers**, **Enable Active OffsetCache** and **Display Broker and Topic Size** and click on **Save** to add the cluster.
You should get a message `Done!` signalling that the cluster has been successfully configured in **Kafka Manager**.
Click on **Go to cluster view**.

In this workshop we will learn how to process messages using the [ksqlDB](https://ksqldb.io/).
We will see different processing patterns applied.
## Connect to ksqlDB CLI
In order to use KSQL, we need to connect to the KSQL engine using the ksqlDB CLI. An instance of a ksqlDB server has been started with the Data Platform and can be reached on port `8088`.
```bash
docker exec -it ksqldb-cli ksql http://ksqldb-server-1:8088
```
You should see the KSQL command prompt:
```bash

ksql>
```
We can use the show command to show topics as well as streams and tables. We have not yet created streams and tables, therefore we won't see anything.
```sql
show streams;
show tables;
show topics;
```
## Create a Stream
Let's create a stream of `transaction`
```sql
CREATE STREAM transaction_s (
email_address VARCHAR KEY,
tx_id VARCHAR,
card_number VARCHAR,
timestamp TIMESTAMP,
amount DECIMAL(12, 2)
) WITH (
kafka_topic = 'transaction',
partitions = 8,
replicas = 3,
value_format = 'avro'
);
```
Now let's view the data in the stream
```sql
SELECT * FROM transaction_s;
```
we have done it as a pull-query (which scans the whole topic behind the stream), and get the following result
```
+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+
|EMAIL_ADDRESS |TX_ID |CARD_NUMBER |TIMESTAMP |AMOUNT |
+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+
Query Completed
Query terminated
```
You can see that the statement ended with no rows. There is no result, as we have not yet send any data to the topic.
Let's change the statement to a push-query by adding `EMIT CHANGES` to the end.
```sql
SELECT * FROM transaction_s EMIT CHANGES;
```
Compared to before, the statement does not end and keeps on running. But there is still now data available.
```
+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+
|EMAIL_ADDRESS |TX_ID |CARD_NUMBER |TIMESTAMP |AMOUNT |
+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+
Press CTRL-C to interrupt
```
Let's change that and add some data to the stream. We could directly produce data to the underlying Kafka topic `transaction` or use the ksqlDB `INSERT` statement, which we will do here. In a new terminal, start again a ksqlDB CLI
```bash
docker exec -it ksqldb-cli ksql http://ksqldb-server-1:8088
```
and add a few transactions
```sql
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', '0cf100ca-993c-427f-9ea5-e892ef350363', '352642227248344', FROM_UNIXTIME(UNIX_TIMESTAMP()), 100.00);
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', '9fe397e3-990e-449a-afcc-7b652a005c99', '999776673238348', FROM_UNIXTIME(UNIX_TIMESTAMP()), 220.00);
```
you will immediately see them returned as a result of the push-query
```sql
+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+
|EMAIL_ADDRESS |TX_ID |CARD_NUMBER |TIMESTAMP |AMOUNT |
+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+
|<EMAIL> |0cf100ca-993c-427f-9ea5-e892ef350363 |352642227248344 |2022-06-06T20:37:27.973 |100.00 |
|<EMAIL> |9fe397e3-990e-449a-afcc-7b652a005c99 |999776673238348 |2022-06-06T20:38:38.343 |220.00 |
```
Stop the push-query by entering `CTRL-C`.
Let's do the pull-query again (the one without the `EMIT CHANGES` clause).
```sql
SELECT * FROM transaction_s
```
This time you can see the historical data which is stored by the stream (the underlying Kafka topic).
```sql
ksql> SELECT * FROM transaction_s;
+-----------------------------+-----------------------------+-----------------------------+-----------------------------+-----------------------------+
|EMAIL_ADDRESS |TX_ID |CARD_NUMBER |TIMESTAMP |AMOUNT |
+-----------------------------+-----------------------------+-----------------------------+-----------------------------+-----------------------------+
|<EMAIL>.com |9fe397e3-990e-449a-afcc-7b652|999776673238348 |2022-07-03T19:05:37.451 |220.00 |
| |a005c99 | | | |
|<EMAIL> |0cf100ca-993c-427f-9ea5-e892e|352642227248344 |2022-07-03T19:05:37.406 |100.00 |
| |f350363 | | | |
Query Completed
Query terminated
ksql>
```
**Note**: be careful with using a pull-query on a Stream, as it could be very resource intensive.
## Filter on the stream
Let's say we are interested in only the transactions, where the amount is larger than `1000`.
This can easily be done using the `WHERE` clause of the push-query.
```sql
SELECT * FROM transaction_s
WHERE amount > 1000.00
EMIT CHANGES;
```
Now let's add some more transactions, some with smaller values some with larger values:
```sql
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', '4c59430a-65a8-4607-bd90-a165a4a9488f', '8878779987897979', FROM_UNIXTIME(UNIX_TIMESTAMP()), 400.20);
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', 'c204eb55-d572-4182-80ab-cfcc0f865861', '352642227248344', FROM_UNIXTIME(UNIX_TIMESTAMP()), 1040.20);
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', 'c204eb55-d572-4182-80ab-cfcc0f865861', '352642227248344', FROM_UNIXTIME(UNIX_TIMESTAMP()), 300.90);
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', '6b69ce08-8506-42c8-900b-079b3f918d97', '9989898989098908', FROM_UNIXTIME(UNIX_TIMESTAMP()), 1090.00);
```
From the total of 4 new transactions, you should only see two in the result, the one which are above 1000.
```
+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+
|EMAIL_ADDRESS |TX_ID |CARD_NUMBER |TIMESTAMP |AMOUNT |
+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+------------------------------------------------------------+
|<EMAIL> |c204eb55-d572-4182-80ab-cfcc0f865861 |352642227248344 |2022-06-06T20:41:27.067 |1040.20 |
|<EMAIL> |6b69ce08-8506-42c8-900b-079b3f918d97 |9989898989098908 |2022-06-06T20:42:13.069 |1090.00 |
```
## Project columns from Stream
Let's see how we can only show the columns we want to see
```ksql
SELECT email_address, amount
FROM transaction_s
EMIT CHANGES;
```
In the 2nd terminal, insert a new transaction
```ksql
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', '8227233d-0b66-4e69-b49b-3cd08b21ab7d', '99989898909808', FROM_UNIXTIME(UNIX_TIMESTAMP()), 55.65);
```
And you should see
```
+---------------------------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------+
|EMAIL_ADDRESS |AMOUNT |
+---------------------------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------+
|<EMAIL> |55.65 |
```
## Using Functions
ksqlDB provides with a large set of [useful functions](https://docs.ksqldb.io/en/latest/developer-guide/ksqldb-reference/functions/).
Let's say that we want to mask the credit card number, then we can use either `MASK` to fully mask or `MASK_RIGHT`/`MASK_LEFT` or `MASK_KEEP_LEFT`/`MASK_KEEP_RIGHT` to partially mask a string field.
```ksql
SELECT email_address, MASK(card_number) card_number, MASK_KEEP_RIGHT(card_number, 4, 'X','x','n','-') card_number_masked_keep4, tx_id, amount
FROM transaction_s
EMIT CHANGES;
```
You can also implement your own [User-Defined Functions](https://docs.ksqldb.io/en/latest/reference/user-defined-functions/), by writing Java hooks.
## Counting Values
Now let's see how we can do some stateful processing. Let's start with a simple count of values.
In the first terminal perform
```sql
SELECT email_address, COUNT(*)
FROM transaction_s
GROUP BY email_address
EMIT CHANGES;
```
Now in the 2nd terminal add some new transactions
```sql
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', '05ed7709-8a18-4e0d-9608-27894750bd43', '352642227248344', FROM_UNIXTIME(UNIX_TIMESTAMP()), 99.95);
```
We can see that the count starts with 0 and will only increase from now.
How can we make the result a bit more meaningful? By adding a time window to the query!
## Counting Values over a Time Window
### Tumbling Window
Let's see the number of transactions within 30 seconds. We use a **tumbling*** window (Fixed-duration, non-overlapping, gap-less windows) first
```sql
SELECT FROM_UNIXTIME (windowstart) as from_ts
, FROM_UNIXTIME (windowend) as to_ts
, email_address
, COUNT(*) as count
FROM transaction_s
WINDOW TUMBLING (SIZE 30 SECONDS)
GROUP BY email_address
EMIT CHANGES;
```
Now in a second window, `INSERT` some more messages.
```sql
+-----------------------------------------------------------------------+-----------------------------------------------------------------------+-----------------------------------------------------------------------+-----------------------------------------------------------------------+
|FROM_TS |TO_TS |EMAIL_ADDRESS |COUNT |
+-----------------------------------------------------------------------+-----------------------------------------------------------------------+-----------------------------------------------------------------------+-----------------------------------------------------------------------+
|2022-07-04T13:36:00.000 |2022-07-04T13:36:30.000 |<EMAIL> |1 |
|2022-07-04T13:36:00.000 |2022-07-04T13:36:30.000 |<EMAIL> |1 |
|2022-07-04T13:36:00.000 |2022-07-04T13:36:30.000 |<EMAIL> |2 |
|2022-07-04T13:36:00.000 |2022-07-04T13:36:30.000 |<EMAIL> |2 |
```
You can see that a result is displayed before the time window is finished. The EMIT clause lets you control the output refinement of your push query. You can switch from `CHANGES` to `FINAL` to tell ksqlDB to wait for the time window to close before a result is returned.
**Note:** `EMIT FINAL` is data driven, i.e., it emit results only if "stream-time" advanced beyond the window close time. "Stream-time" depends on the observed timestamps of your input record, and thus, if you stop sending input records, "stream-time" does not advance further. If you stop sending data, the last window might never be closed, and thus you never see a result for it.
**Note:** There are some memory considerations with the `FINAL` feature that could cause unbounded growth and eventual an OOM exception. The feature is still in development/beta and we'll definitely document it when it's complete!
### Hopping Window
We can easily switch to a **hopping** window (Fixed-duration, overlapping windows) with 10 seconds overlap
```sql
SELECT FROM_UNIXTIME (WINDOWSTART) as from_ts
, FROM_UNIXTIME (WINDOWEND) as to_ts
, email_address
, COUNT(*) as count
FROM transaction_s
WINDOW HOPPING (SIZE 30 SECONDS, ADVANCE BY 10 SECONDS)
GROUP BY email_address
EMIT CHANGES;
```
## Create a ksqlDB Table holding Customers
A table is a mutable, partitioned collection that models change over time. In contrast with a stream, which represents a historical sequence of events, a table represents what is true as of "now".
Tables work by leveraging the keys of each row. If a sequence of rows shares a key, the last row for a given key represents the most up-to-date information for that key's identity. A background process periodically runs and deletes all but the newest rows for each key.
Let's use a table to model customers.
Create the table `customer_t` and put some data in it
```sql
DROP TABLE customer_t;
CREATE TABLE customer_t (email_address VARCHAR PRIMARY KEY, first_name VARCHAR, last_name VARCHAR, category VARCHAR)
WITH (KAFKA_TOPIC='customer',
VALUE_FORMAT='AVRO',
PARTITIONS=8,
REPLICAS=3);
```
The table is backed by the topic called `customer`. This topic is automatically created using the settings you provide. If it should be a compacted log topic (which could make sense), you have to create it manually first, before creating the table.
Now let's add some data to the KSQL table:
```sql
INSERT INTO customer_t (email_address, first_name, last_name, category) VALUES ('<EMAIL>', 'Peter', 'Muster', 'A');
INSERT INTO customer_t (email_address, first_name, last_name, category) VALUES ('<EMAIL>', 'Barbara', 'Sample', 'B');
```
With that in place, can we use a Pull-Query to retrieve a customer? Let's try that
```sql
SELECT *
FROM customer_t
WHERE email_address = '<EMAIL>';
```
will give an error
```sql
ksql> SELECT *
>FROM customer_t
>WHERE email_address = '<EMAIL>';
The `CUSTOMER_T` table isn't queryable. To derive a queryable table, you can do 'CREATE TABLE QUERYABLE_CUSTOMER_T AS SELECT * FROM CUSTOMER_T'. See https://cnfl.io/queries for more info.
Add EMIT CHANGES if you intended to issue a push query.
```
You can provide the `SOURCE` clause to enable running pull queries on the table. The `SOURCE` clause runs an internal query for the table to create a materialized state that's used by pull queries. When you create a `SOURCE` table, the table is created as read-only. For a read-only table, INSERT, DELETE TOPIC, and DROP TABLE statements aren't permitted.
That's why we reuse the topic `customer` from the table created above, just to see a `SOURCE` table in action. In a real-life situation, usually the data behind the table is created directly either by a connector or a stream processing application.
Let's create a new `SOURCE` table by adding the `SOURCE` keyword:
```sql
DROP TABLE customer_st;
CREATE SOURCE TABLE customer_st (email_address VARCHAR PRIMARY KEY, first_name VARCHAR, last_name VARCHAR, category VARCHAR)
WITH (KAFKA_TOPIC='customer',
VALUE_FORMAT='AVRO',
PARTITIONS=8,
REPLICAS=3);
```
Now on that table a pull-query works:
```sql
SELECT *
FROM customer_st
WHERE email_address = '<EMAIL>';
```
Let's drop that table as we no longer need it
```sql
DROP TABLE customer_st;
```
## Join Stream with a Table
Now let's see how we can enrich the stream of data (transactions) with some static data (customer). We want to do a join between the stream and a table (`customer_t`) holding all the customer data, we just created.
So let's join the table to the transaction stream. We create another push query, which will continuously run.
```sql
SELECT * FROM transaction_s AS tra
LEFT JOIN customer_t AS cus
ON (tra.email_address = cus.email_address)
EMIT CHANGES;
```
In the 2nd terminal, insert a new message into the `transaction_s` stream
```sql
INSERT INTO transaction_s (email_address, tx_id, card_number, timestamp, amount)
VALUES ('<EMAIL>', '05ed7709-8a18-4e0d-9608-27894750bd43', '352642227248344', FROM_UNIXTIME(UNIX_TIMESTAMP()), 99.95);
```
and you should see the result of the join in the 1st terminal window.
```bash
ksql> SELECT * FROM transaction_s AS tra
>LEFT JOIN customer_t AS cus
>ON (tra.email_address = cus.email_address)
>EMIT CHANGES;
+---------------------+---------------------+---------------------+---------------------+---------------------+---------------------+---------------------+---------------------+---------------------+
|TRA_EMAIL_ADDRESS |TRA_TX_ID |TRA_CARD_NUMBER |TRA_TIMESTAMP |TRA_AMOUNT |CUS_EMAIL_ADDRESS |CUS_FIRST_NAME |CUS_LAST_NAME |CUS_CATEGORY |
+---------------------+---------------------+---------------------+---------------------+---------------------+---------------------+---------------------+---------------------+---------------------+
|<EMAIL>|0cf100ca-993c-427f-9e|352642227248344 |2022-07-04T15:44:14.8|100.00 |<EMAIL>|Peter |Muster |A |
| |a5-e892ef350363 | |98 | | | | | |
|<EMAIL>|9fe397e3-990e-449a-af|999776673238348 |2022-07-04T15:44:14.9|220.00 |<EMAIL>|Barbara |Sample |B |
|om |cc-7b652a005c99 | |76 | |om | | | |
Press CTRL-C to interrupt
```
If we are happy with the result, we can materialise it by using a CSAS (CREATE STREAM AS SELECT) statement.
```sql
CREATE STREAM transaction_customer_s
WITH (
KAFKA_TOPIC = 'transaction_customer',
VALUE_FORMAT = 'AVRO',
PARTITIONS = 8,
REPLICAS = 3
)
AS
SELECT *
FROM transaction_s AS tra
LEFT JOIN customer_t AS cus
ON (tra.email_address = cus.email_address)
EMIT CHANGES;
```
If you describe the stream, then you will see that KSQL has derived the column names so that they are unique (using the aliases)
```sql
ksql> describe transaction_customer_s;
Name : TRANSACTION_CUSTOMER_S
Field | Type
--------------------------------------------
TRA_EMAIL_ADDRESS | VARCHAR(STRING) (key)
TRA_TX_ID | VARCHAR(STRING)
TRA_CARD_NUMBER | VARCHAR(STRING)
TRA_TIMESTAMP | TIMESTAMP
TRA_AMOUNT | DECIMAL(12, 2)
CUS_EMAIL_ADDRESS | VARCHAR(STRING)
CUS_FIRST_NAME | VARCHAR(STRING)
CUS_LAST_NAME | VARCHAR(STRING)
CUS_CATEGORY | VARCHAR(STRING)
--------------------------------------------
For runtime statistics and query details run: DESCRIBE <Stream,Table> EXTENDED;
```
You can of course also provide your own column aliases by listing the columns in the `SELECT` list, instead of just using the `*`.
Now you can get the result either by querying the new stream `transaction_customer_s`
```sql
SELECT *
FROM transaction_customer_s
EMIT CHANGES;
```
or by consuming directly from the underlying topic called `transaction_customer`.
```bash
docker run -it --network=host edenhill/kcat:1.7.1 -b dataplatform -t transaction_customer -s value=avro -r http://dataplatform:8081
```
## Total amount of transaction value by category
Now with the enriched stream of transactions and customers, we can get the total amount of transactions by customer category over a tumbling window of 30 seconds.
```ksql
SELECT cus_category AS category
, SUM(tra_amount) AS amount
, FROM_UNIXTIME (WINDOWSTART) AS from_ts
, FROM_UNIXTIME (WINDOWEND) AS to_ts
FROM transaction_customer_s
WINDOW TUMBLING (SIZE 30 SECONDS, RETENTION 120 SECONDS, GRACE PERIOD 60 SECONDS)
GROUP BY cus_category
EMIT CHANGES;
```
We create a **tumbling window** of 30 seconds size, with a **grace period** of 60 seconds (accepting out-of-order events which are older than 1 minute) and a **window retention** of 120 seconds (the number of windows in the past that ksqlDB retains, so that they are available for Pull-Queries).
**Note:** the specified retention period should be larger than the sum of window size and any grace period.
To materialise the result, we can create another table
```sql
CREATE TABLE total_amount_per_category_t
AS
SELECT cus_category AS category
, SUM(tra_amount) AS amount
, FROM_UNIXTIME (WINDOWSTART) AS from_ts
, FROM_UNIXTIME (WINDOWEND) AS to_ts
FROM transaction_customer_s
WINDOW TUMBLING (SIZE 30 SECONDS, RETENTION 120 SECONDS, GRACE PERIOD 60 SECONDS)
GROUP BY cus_category
EMIT CHANGES;
```
We haven't specified an underlying topic, so KSQL will create one with the same name. You can cross-check by doing a DESCRIBE ... EXTENDED
```sql
ksql> describe total_amount_per_category_t extended;
Name : TOTAL_AMOUNT_PER_CATEGORY_T
Type : TABLE
Timestamp field : Not set - using <ROWTIME>
Key format : KAFKA
Value format : AVRO
Kafka topic : TOTAL_AMOUNT_PER_CATEGORY_T (partitions: 8, replication: 3)
Statement : CREATE TABLE TOTAL_AMOUNT_PER_CATEGORY_T WITH (KAFKA_TOPIC='TOTAL_AMOUNT_PER_CATEGORY_T', PARTITIONS=8, REPLICAS=3) AS SELECT
TRANSACTION_CUSTOMER_S.CUS_CATEGORY CATEGORY,
SUM(TRANSACTION_CUSTOMER_S.TRA_AMOUNT) AMOUNT
FROM TRANSACTION_CUSTOMER_S TRANSACTION_CUSTOMER_S
WINDOW TUMBLING ( SIZE 30 SECONDS , RETENTION 120 SECONDS , GRACE PERIOD 60 SECONDS )
GROUP BY TRANSACTION_CUSTOMER_S.CUS_CATEGORY
EMIT CHANGES;
Field | Type
-------------------------------------------------------------------
CATEGORY | VARCHAR(STRING) (primary key) (Window type: TUMBLING)
AMOUNT | DECIMAL(12, 2)
-------------------------------------------------------------------

Pull-query to get the current state for category with the `windowstart` and `windowend` converted to a readable timestamp
```sql
SELECT category

```
Insert a transaction with Event Time (`ROWTIME`) 60 seconds ago:
```sql
INSERT INTO transaction_s (ROWTIME, email_address, tx_id, card_number, timestamp, amount)
VALUES (UNIX_TIMESTAMP() - 60000, '<EMAIL>', '0cf100ca-993c-427f-9ea5-e892ef350363', '352642227248344', FROM_UNIXTIME(UNIX_TIMESTAMP()), 100.00);
```
It will be counted in the previous window.
Insert a transaction with Event Time (`ROWTIME`) 3 minutes ago:
```sql
INSERT INTO transaction_s (ROWTIME, email_address, tx_id, card_number, timestamp, amount)
VALUES (UNIX_TIMESTAMP() - 180000, '<EMAIL>', '0cf100ca-993c-427f-9ea5-e892ef350363', '352642227248344', FROM_UNIXTIME(UNIX_TIMESTAMP()), 100.00);
```
it will not be treated as a late arrival, as if falls out of the grace period.
## Anomalies
If a single credit card is transacted many times within a short duration, there's probably something suspicious going on. A table is an ideal choice to model this because you want to aggregate events over time and find activity that spans multiple events.
```sql
CREATE TABLE possible_anomalies WITH (
kafka_topic = 'possible_anomalies',
VALUE_AVRO_SCHEMA_FULL_NAME = 'io.ksqldb.tutorial.PossibleAnomaly'
) AS
SELECT card_number AS `card_number_key`,
as_value(card_number) AS `card_number`,
latest_by_offset(email_address) AS `email_address`,
count(*) AS `n_attempts`,
sum(amount) AS `total_amount`,
collect_list(tx_id) AS `tx_ids`,
WINDOWSTART as `start_boundary`,
WINDOWEND as `end_boundary`
FROM transaction_s
WINDOW TUMBLING (SIZE 30 SECONDS, RETENTION 1000 DAYS)
GROUP BY card_number
HAVING count(*) >= 3
EMIT CHANGES;
```
Now create 3 transactions for the same credit card number within 30 seconds and it show up as a potential anomaly.
## Rest API
You can execute a ksqlDB `SELECT` directly over the [REST API](https://docs.ksqldb.io/en/latest/developer-guide/api/) using a `POST` on `/query-stream` endpoint
```bash
curl -X POST -H 'Content-Type: application/vnd.ksql.v1+json' -i http://dataplatform:8088/query-stream --data '{
"sql": "SELECT card_number, amount, tx_id FROM transaction_s EMIT CHANGES;",
"properties": {
"ksql.streams.auto.offset.reset": "latest"
}
}'
```
This way we can directly get the data into a GUI client.

For the various Twitter consumer of this course, we will connect to twitter through the so-called [Filter Stream API](https://developer.twitter.com/en/docs/tweets/filter-realtime/overview.html). This allows to set some filter options, which defines the Tweets we are interested in. Filters can be set on Terms, Geographic Location, Language and User.
In order to use the Twitter [Filter Stream API](https://developer.twitter.com/en/docs/tweets/filter-realtime/overview.html), we first have to create a Twitter application. If you don't have a Twitter user yet, you also have to create an account, which you can do from the sign in page below. To access the Twitter Application managment, navigate to <http://apps.twitter.com>.
Click on **Sign in** link on the top right corner.
Enter the **Username** and **Password** of your twitter handle into the corresponding fields. If you don’t yet have a twitter handle, then click on the small **Sign up now** link to register at twitter.
Clock on **Create New App** in the upper right corner to create a new Twitter application.
Enter **Name**, **Description**, **Website**
Click on **Create your Twitter application**.
Click on **Keys and Access Tokens** to get the credentials.
Click on **Create my access tokens**
The Acess token pair gets generated and is available to be used.
Note that you will need the **Consumer Key**, the **Consumer Secret** the **Access Token** and the **Access Token Secret** when using the Twitter API and conneting with OAuth protocol.

}<file_sep># Using Kafka from Scala
In this workshop we will learn how to use Apache Kafka from Scala.
## Setup
### Creating the necessary Kafka Topic
We will use the topic `test-node-topic` in the Producer and Consumer code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
Connect to the `kafka-1` container
```
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```
kafka-topics --create \
--replication-factor 3 \
--partitions 12 \
--topic test-scala-topic \
--bootstrap-server kafka-1:19092
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing the **Kafka Producer** which uses Avro for the serialisation.
## Create a Scala Project
Add the following code to `build.sbt`
```bash
import sbt.fullRunTask
ThisBuild / version := "0.1.0-SNAPSHOT"
ThisBuild / scalaVersion := "2.13.10"
lazy val root = (project in file("."))
.settings(
name := "scala-kafka",
resolvers += "Confluent Repo" at "https://packages.confluent.io/maven",
libraryDependencies ++= (Dependencies.rootDependencies ++ Dependencies.kafkaClientsDeps),
libraryDependencies ++= (Dependencies.testDependencies map(_ % Test)),
fullRunTask(produce, Compile, s"com.trivadis.kafkaws.producer.Producer")
)
lazy val produce: TaskKey[Unit] = taskKey[Unit]("Message Production")
lazy val consume: TaskKey[Unit] = taskKey[Unit]("Message Consumption")
```
Add the following code to `Dependencies.scala`
```
import sbt._
object Dependencies {
lazy val rootDependencies: List[ModuleID] =
"org.typelevel" %% "cats-core" % "2.1.1" ::
"ch.qos.logback" % "logback-classic" % "1.4.5" :: Nil
lazy val kafkaClientsDeps: List[ModuleID] =
"org.apache.kafka" % "kafka-clients" % "3.3.2" :: Nil
lazy val testDependencies: List[ModuleID] =
"org.scalatest" %% "scalatest" % "3.2.3" ::
"org.scalactic" %% "scalactic" % "3.2.3" ::
"org.scalacheck" %% "scalacheck" % "1.15.1" ::
"org.typelevel" %% "cats-core" % "2.3.0" :: Nil
}
```
# Create Kafka Producer
Next we are going to create the producer application by pasting the following Scala code into a file named `Producer.scala`.
```scala
package com.trivadis.kafkaws.producer
import java.util.Properties
import org.apache.kafka.clients.producer._
object KafkaProducerSync {
val bootstrapServers = "dataplatform:9092,dataplatform:9093"
val topic = "test-scala-topic"
val props: Properties = {
val p = new Properties()
p.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers)
p.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.LongSerializer")
p.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringSerializer")
p.put(ProducerConfig.ACKS_CONFIG, "all")
// p.put(ProducerConfig.BATCH_SIZE_CONFIG, 16384)
// p.put(ProducerConfig.LINGER_MS_CONFIG, 1)
// p.put(ProducerConfig.RETRIES_CONFIG, 0)
p
}
def main(args: Array[String]): Unit = {
val sendMessageCount = args(0).toString.toInt
val waitMsInBetween = args(1).toString.toInt
val id = args(2).toString.toLong;
val producer = new KafkaProducer[Long, String](props)
for (i <- 1 to sendMessageCount) {
val metadata = if (id > 0)
producer.send(new ProducerRecord(topic, id, s"[${i}] Hello Kafka ${i}"))
else
producer.send(new ProducerRecord(topic, s"[${i}] Hello Kafka ${i}"))
println(s"[${id}] sent record(topic=${metadata.get().topic()} partition=${metadata.get().partition()}")
// Simulate slow processing
Thread.sleep(waitMsInBetween)
}
producer.close()
}
}
```
# Kafka Consumer
Next let's create the consumer by pasting the following code into a file named `consumer.go`.
```scala
package com.trivadis.kafkaws.consumer
import java.util.{Collections, Properties}
import org.apache.kafka.clients.consumer.{CommitFailedException, ConsumerConfig, KafkaConsumer}
object KafkaConsumerExample {
import scala.collection.JavaConverters._
val bootstrapServers = "dataplatform:9092,dataplatform:9093"
val groupId = "kafka-example"
val topics = "test-scala-topic"
val props: Properties = {
val p = new Properties()
p.put(ConsumerConfig.GROUP_ID_CONFIG, groupId)
p.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers)
p.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.LongDeserializer")
p.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer")
p.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest") // default is latest
p
}
def main(args: Array[String]): Unit = {
val consumer = new KafkaConsumer[Long, String](props)
consumer.subscribe(Collections.singletonList(this.topics))
while (true) {
val records = consumer.poll(1000).asScala
for (record <- records) {
println("Message: (key: " +
record.key() + ", with value: " + record.value() +
") at on partition " + record.partition() + " at offset " + record.offset())
}
try
consumer.commitSync
catch {
case e: CommitFailedException =>
}
}
consumer.close()
}
}
```

<file_sep># Working with Kafka from Kotlin
In this workshop we will learn how to produce and consume messages using the [Kafka Java API](https://kafka.apache.org/documentation/#api).
## Create the project in your favourite IDE
Create a new Maven Project (using the functionality of your favourite IDE) and use `com.trivadis.kafkaws` for the **Group Id** and `kotlin-simple-kafka` for the **Artifact Id**.
Navigate to the **pom.xml** and double-click on it. The POM Editor will be displayed.
You can either use the GUI to edit your pom.xml or click on the last tab **pom.xml** to switch to the "code view". Let's do that.
You will see the still rather empty definition.
```xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

## Creating the necessary Kafka Topic
We will use the topic `test-kotlin-topic` in the Producer and Consumer code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
Connect to the `kafka-1` container
```bash
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```bash
kafka-topics --create \
--replication-factor 3 \
--partitions 12 \
--topic test-kotlin-topic \
--bootstrap-server kafka-1:19092
```
Cross check that the topic has been created.
```bash
kafka-topics --list --bootstrap-server kafka-1:19092
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing a **Kafka Producer**.
## Create a Kafka Producer
Let's first create a producer in synchronous mode.
### Using the Synchronous mode
First create a new Package `com.trivadis.kafkaws.producer` in the folder **src/main/kotlin**.
Create a new Kotlin File `KafkaProducerSync` in the package `com.trivadis.kafkaws.producer` just created.
Add the following code to the empty file to start with the Kafka Producer, specifying the bootstrap server and topic constants
```kotlin
@file:JvmName("KafkaProducerSync")
package com.trivadis.kafkaws.producer
import org.apache.kafka.clients.producer.KafkaProducer
import org.apache.kafka.clients.producer.ProducerConfig.*
import org.apache.kafka.clients.producer.ProducerRecord
import org.apache.kafka.clients.producer.RecordMetadata
import org.apache.kafka.common.serialization.LongSerializer
import org.apache.kafka.common.serialization.StringSerializer
import java.time.LocalDateTime
import java.util.*
private val TOPIC = "test-kotlin-topic"
private val BOOTSTRAP_SERVERS = "dataplatform:9092,dataplatform:9093"
```
Kafka provides a synchronous send method to send a record to a topic. Let’s use this method to send a number of messages to the Kafka topic we created earlier
```kotlin
fun runProducer(sendMessageCount: Int, waitMsInBetween: Long, id: Long) {
// Define properties.
val props = Properties()
props[BOOTSTRAP_SERVERS_CONFIG] = BOOTSTRAP_SERVERS
props[ACKS_CONFIG] = "all"
props[KEY_SERIALIZER_CLASS_CONFIG] = LongSerializer::class.qualifiedName
props[VALUE_SERIALIZER_CLASS_CONFIG] = StringSerializer::class.qualifiedName
KafkaProducer<Long, String>(props).use { producer ->
repeat(sendMessageCount) { index ->
val time = System.currentTimeMillis();
val value = "[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now()
val m = producer.send(ProducerRecord(TOPIC, value)).get()
val elapsedTime = System.currentTimeMillis() - time;
println("Produced record to topic ${m.topic()} partition [${m.partition()}] @ offset ${m.offset()} time=${elapsedTime}")
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
producer.flush()
}
}
```
Next you define the main method.
```kotlin
fun main(args: Array<String>) {
if (args.size == 0) {
runProducer(100, 10, 0)
} else {
runProducer(args[0].toInt(), args[1].toLong(), args[2].toLong())
}
}
```
The `main()` method accepts 3 parameters, the number of messages to produce, the time in ms to wait in-between sending each message and the ID of the producer.
Add the `exec-maven-plugin` to the maven plugins
```xml
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>producer</id>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.trivadis.kafkaws.producer.KafkaProducerSync</mainClass>
</configuration>
</execution>
</executions>
</plugin>
```
Now run it using the `mvn exec:java` command. It will generate 1000 messages, waiting 100ms in-between sending each message and use 0 for the ID, which will set the key to `null`.
```bash
mvn clean package -Dmaven.test.skip=true
mvn exec:java@producer -Dexec.args="1000 100 0"
```
**Note**: if your maven version does not support profiles, then you have to specify the main class as well: `mvn exec:java -Dexec.mainClass="com.trivadis.kafkaws.producer.KafkaProducerSync" -Dexec.args="1000 100 0"`
Use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-kotlin-topic`.
```bash
kcat -b dataplatform -t test-kotlin-topic -f 'Part-%p => %k:%s\n' -q
```
```bash

```
### Using the Id field as the key
If we specify an id <> `0` when runnning the producer, the id is used as the key
```kotlin
fun runProducer(sendMessageCount: Int, waitMsInBetween: Int, id: Long) {
// Define properties.
val props = Properties()
props[BOOTSTRAP_SERVERS_CONFIG] = BOOTSTRAP_SERVERS
props[ACKS_CONFIG] = "all"
props[KEY_SERIALIZER_CLASS_CONFIG] = LongSerializer::class.qualifiedName
props[VALUE_SERIALIZER_CLASS_CONFIG] = StringSerializer::class.qualifiedName
val key = if (id > 0) id else null
KafkaProducer<Long, String>(props).use { producer ->
repeat(sendMessageCount) { index ->
val time = System.currentTimeMillis();
val value = "[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now()
val m = producer.send(ProducerRecord(TOPIC, key, value)).get()
```
So let's run it for id=`10`
```bash
mvn exec:java@producer -Dexec.args="1000 100 10"
```
you should see that now all messages will be sent to the same partition.
### Changing to Asynchronous mode
The following kotlin file shows the same logic but this time using the asynchronous way for sending records to Kafka. The difference can be seen in the `runProducerAsync` method.
```kotlin
@file:JvmName("KafkaProducerAsync")
package com.trivadis.kafkaws.producer
import org.apache.kafka.clients.producer.KafkaProducer
import org.apache.kafka.clients.producer.ProducerConfig.*
import org.apache.kafka.clients.producer.ProducerRecord
import org.apache.kafka.clients.producer.RecordMetadata
import org.apache.kafka.common.serialization.LongSerializer
import org.apache.kafka.common.serialization.StringSerializer
import java.time.LocalDateTime
import java.util.*
private val TOPIC = "test-kotlin-topic"
private val BOOTSTRAP_SERVERS = "dataplatform:9092,dataplatform:9093"
fun runProducerAsync(sendMessageCount: Int, waitMsInBetween: Long, id: Long) {
// Define properties.
val props = Properties()
props[BOOTSTRAP_SERVERS_CONFIG] = BOOTSTRAP_SERVERS
props[ACKS_CONFIG] = "all"
props[KEY_SERIALIZER_CLASS_CONFIG] = LongSerializer::class.qualifiedName
props[VALUE_SERIALIZER_CLASS_CONFIG] = StringSerializer::class.qualifiedName
val key = if (id > 0) id else null
KafkaProducer<Long, String>(props).use { producer ->
repeat(sendMessageCount) { index ->
val time = System.currentTimeMillis();
val value = "[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now()
producer.send(ProducerRecord(TOPIC, key, value)) { m: RecordMetadata, e: Exception? ->
when (e) {
// no exception, good to go!
null -> {
val elapsedTime = System.currentTimeMillis() - time;
println("Produced record to topic ${m.topic()} partition [${m.partition()}] @ offset ${m.offset()} time=${elapsedTime}")
}
// print stacktrace in case of exception
else -> e.printStackTrace()
}
}
}
producer.flush()
}
}
fun main(args: Array<String>) {
if (args.size == 0) {
runProducerAsync(100, 10, 0)
} else {
runProducerAsync(args[0].toInt(), args[1].toLong(), args[2].toLong())
}
}
```
add a new profile to the `pom.xml`
```xml
<execution>
<id>producer-async</id>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.trivadis.kafkaws.producer.KafkaProducerAsync</mainClass>
</configuration>
</execution>
```
And now build and run it for id=`10`
```bash
mvn clean package
mvn exec:java@producer-async -Dexec.args="1000 100 10"
```
## Create a Kafka Consumer
Just like we did with the producer, you need to specify bootstrap servers. You also need to define a `group.id` that identifies which consumer group this consumer belongs. Then you need to designate a Kafka record key deserializer and a record value deserializer. Then you need to subscribe the consumer to the topic you created in the producer tutorial.
### Kafka Consumer with Automatic Offset Committing
First create a new Package `com.trivadis.kafkaws.consumer` in the folder **src/main/kotlin**.
Create a new Kotlin file `KafkaConsumerAuto` in the package `com.trivadis.kafkaws.consumer` just created.
Add the following code to the empty class.
Now, that we imported the Kafka classes and defined some constants, let’s create a Kafka producer.
First imported the Kafka classes, define some constants and create the Kafka consumer.
```kotlin
@file:JvmName("KafkaConsumerAuto")
package com.trivadis.kafkaws.consumer
import org.apache.kafka.clients.consumer.ConsumerConfig.*
import org.apache.kafka.clients.consumer.KafkaConsumer
import org.apache.kafka.common.serialization.LongDeserializer
import org.apache.kafka.common.serialization.StringDeserializer
import java.time.Duration
import java.util.*
private val TOPIC = "test-kotlin-topic"
private val BOOTSTRAP_SERVERS = "dataplatform:9092,dataplatform:9093"
fun runConsumer(waitMsInBetween: Long) {
// Define properties.
val props = Properties()
props[BOOTSTRAP_SERVERS_CONFIG] = BOOTSTRAP_SERVERS
props[GROUP_ID_CONFIG] = "kotlin-simple-consumer"
props[AUTO_COMMIT_INTERVAL_MS_CONFIG] = 10000
props[KEY_DESERIALIZER_CLASS_CONFIG] = LongDeserializer::class.qualifiedName
props[VALUE_DESERIALIZER_CLASS_CONFIG] = StringDeserializer::class.qualifiedName
val consumer = KafkaConsumer<Long, String>(props).apply {
subscribe(listOf(TOPIC))
}
consumer.use {
while(true) {
val messages = consumer.poll(Duration.ofMillis(100))
messages.forEach {
println("Consumed record [Key: ${it.key()}, Value: ${it.value()}] @ Partition: ${it.partition()}, Offset: ${it.offset()}")
}
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
fun main(args: Array<String>) {
if (args.size == 0) {
runConsumer(10)
} else {
runConsumer(args[0].toInt())
}
}
```
We configured the consumer to use the `auto.commit` mode (by not setting it, as it is by default set to `true`) and set the commit interval to `10 seconds`.
Next you define the main method. You can pass the amount of time the consumer spends for processing each record consumed.
```kotlin
fun main(args: Array<String>) {
if (args.size == 0) {
runConsumer(10)
} else {
runConsumer(args[0].toInt())
}
}
```
The main method just calls `runConsumer`.
Before we run the consumer, let's add a configuration in `log4j.properties`, by creating that file in `src/main/resources` and add the following lines
```properties
log4j.rootLogger=INFO, out
# CONSOLE appender not used by default
log4j.appender.out=org.apache.log4j.ConsoleAppender
log4j.appender.out.layout=org.apache.log4j.PatternLayout
log4j.appender.out.layout.ConversionPattern=[%30.30t] %-30.30c{1} %-5p %m%n
log4j.logger.org.apache.kafka.clients.consumer.internals.ConsumerCoordinator=DEBUG
```
If will show a DEBUG message whenever the auto commit is executed.
Before we can run it, add the consumer to the `<executions>` section in the `pom.xml`.
```xml
<execution>
<id>consumer</id>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.trivadis.kafkaws.consumer.KafkaConsumerAuto</mainClass>
</configuration>
</execution>
```
Now run it using the `mvn exec:java` command.
```bash
mvn clean package -Dmaven.test.skip=true
mvn exec:java@consumer -Dexec.args="0"
```
**Note**: if your maven version does not support profiles, then you have to specify the main class as well: `mvn exec:java -Dexec.mainClass="com.trivadis.kafkaws.consumer.KafkaConsumerAuto" -Dexec.args="0"`
on the console you should see an output similar to the one below, with some Debug messages whenever the auto-commit is happening
```bash

```
### Kafka Consumer with Manual Offset Control
Create a new Kotlin file `KafkaConsumerManual` in the package `com.trivadis.kafkaws.consumer` just created by copy-pasting from the class `KafkaConsumerAuto`.
Replace the implementation with the code below.
```kotlin
@file:JvmName("KafkaConsumerManual")
package com.trivadis.kafkaws.consumer
import org.apache.kafka.clients.consumer.ConsumerConfig.*
import org.apache.kafka.clients.consumer.KafkaConsumer
import org.apache.kafka.common.serialization.LongDeserializer
import org.apache.kafka.common.serialization.StringDeserializer
import java.time.Duration
import java.util.*
private val TOPIC = "test-kotlin-topic"
private val BOOTSTRAP_SERVERS = "dataplatform:9092,dataplatform:9093"
fun runConsumerManual(waitMsInBetween: Long) {
// Define properties.
val props = Properties()
props[BOOTSTRAP_SERVERS_CONFIG] = BOOTSTRAP_SERVERS
props[GROUP_ID_CONFIG] = "kotlin-simple-consumer"
props[ENABLE_AUTO_COMMIT_CONFIG] = false
props[KEY_DESERIALIZER_CLASS_CONFIG] = LongDeserializer::class.qualifiedName
props[VALUE_DESERIALIZER_CLASS_CONFIG] = StringDeserializer::class.qualifiedName
val consumer = KafkaConsumer<Long, String>(props).apply {
subscribe(listOf(TOPIC))
}
consumer.use {
while(true) {
val messages = consumer.poll(Duration.ofMillis(100))
messages.forEach {
println("Consumed record [Key: ${it.key()}, Value: ${it.value()}] @ Partition: ${it.partition()}, Offset: ${it.offset()}")
}
consumer.commitSync();
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
fun main(args: Array<String>) {
if (args.size == 0) {
runConsumerManual(10)
} else {
runConsumerManual(args[0].toInt())
}
}
```
Before we can run it, add the consumer to the `<executions>` section in the `pom.xml`.
```xml
<execution>
<id>consumer-manual</id>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.trivadis.kafkaws.consumer.KafkaConsumerManual</mainClass>
</configuration>
</execution>
```
Now run it using the `mvn exec:java` command.
```bash
mvn clean package -Dmaven.test.skip=true
mvn exec:java@consumer-manual -Dexec.args="0"
```
## Try running Producer and Consumer
Run the consumer from your IDE or Terminal (Maven). Then run the producer from above from your IDE or Terminal (Maven). You should see the consumer get the records that the producer sent.
### Three Consumers in same group and one Producer sending 25 messages
Start the consumer 3 times by executing the following command in 3 different terminal windows.
```bash
mvn exec:java@consumer -Dexec.args="0"
```
and then start the producer
```bash
mvn exec:java@producer -Dexec.args="25 0 0"
```
#### Producer Output
```bash

1 - Consumer Record:(Key: null, Value: [0] Hello Kafka 24, Partition: 0, Offset: 287)
```
#### Consumer 2 Output (same consumer group)
```bash
1 - Consumer Record:(Key: null, Value: [0] Hello Kafka 2, Partition: 5, Offset: 284)
2 - Consumer Record:(Key: null, Value: [0] Hello Kafka 6, Partition: 3, Offset: 283)

2 - Consumer Record:(Key: null, Value: [0] Hello Kafka 10, Partition: 5, Offset: 285)
2 - Consumer Record:(Key: null, Value: [0] Hello Kafka 11, Partition: 4, Offset: 1285)
1 - Consumer Record:(Key: null, Value: [0] Hello Kafka 14, Partition: 3, Offset: 284)
1 - Consumer Record:(Key: null, Value: [0] Hello Kafka 18, Partition: 5, Offset: 286)

1 - Consumer Record:(Key: null, Value: [0] Hello Kafka 20, Partition: 7, Offset: 286)
1 - Consumer Record:(Key: null, Value: [0] Hello Kafka 23, Partition: 6, Offset: 285)
```
**Questions**
- Which consumer owns partition 10?
- How many ConsumerRecords objects did Consumer 0 get?
- What is the next offset from Partition 11 that Consumer 2 should get?
- Why does each consumer get unique messages?
### Three Consumers in same group and one Producer sending 10 messages using key
Start the consumer 3 times by executing the following command in 3 different terminal windows.
```bash
mvn exec:java@consumer -Dexec.args="0"
```
and then start the producer (using 10 for the ID)
```bash
mvn exec:java@producer -Dexec.args="1000 100 10"
```
#### Producer Output
```bash
[10] sent record(key=10 value=[10] Hello Kafka 0) meta(partition=3, offset=289) time=326
[10] sent record(key=10 value=[10] Hello Kafka 1) meta(partition=3, offset=290) time=7

# Querying data in Azure Data Lake Storage Gen2 from Trino (formerly PrestoSQL)
This tutorial will show how to query Azure Data Lake Storage Gen2 (ADLS) with Hive and Trino.
## Initialise a platform
First [initialise a platys-supported data platform](../../getting-started) with the following services enabled
```
platys init --enable-services TRINO,HIVE_METASTORE,AZURECLI,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.15.0
```
add the following property to `config.yml`
```
TRINO_edition: 'oss'
```
Now generate and start the data platform.
```bash
platys gen
docker-compose up -d
```
## Create Data in Azure Data Lake Storage
first login using
```bash
docker exec -ti azurecli az login
```
Navigate to the website as requested and enter the code provided by the login command and authenticate yourself to Azure.
Now create the container
```
docker exec -ti azurecli az storage fs create -n flight-data --account-name gusstorage --auth-mode login
```
create some folders
```bash
docker exec -ti azurecli az storage fs directory create -n /landing/airports/ -f flight-data --account-name gusstorage
docker exec -ti azurecli az storage fs directory create -n /landing/plane/ -f flight-data --account-name gusstorage
```
and upload some data
```bash
docker exec -ti azurecli az storage fs file upload -s "data-transfer/flight-data/airports.json" -p /landing/airports/airports.json -f flight-data --account-name gusstorage
docker exec -ti azurecli az storage fs file upload -s "data-transfer/flight-data/plane-data.json" -p /landing/plane/plane-data.json -f flight-data --account-name gusstorage
```
## Create a table in Hive
On the docker host, start the Hive CLI
```
docker exec -ti hive-metastore hive
```
and create a new database `flight_db` and in that database a table `plane_t`:
```
create database flight_db;
use flight_db;
CREATE EXTERNAL TABLE plane_t (tailnum string
, type string
, manufacturer string , issue_date string
, model string
, status string
, aircraft_type string
, engine_type string
, year string )
ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
LOCATION 'abfs://flight-data@gusstorage.dfs.core.windows.net/landing/plane';
```
## Query Table from Trino
Next let's query the data from Trino. Connect to the Trino CLI using
```
docker exec -it trino-cli trino --server trino-1:8080
```
Now on the Trino command prompt, switch to the right database.
```
use adls.flight_db;
```
Let's see that there is one table available:
```
show tables;
```
We can see the `plane_t` table we created in the Hive Metastore before
```
presto:default> show tables;
Table
---------------
plane_t
(1 row)
```
```
SELECT * FROM plane_t;
```
```
SELECT year, count(*)
FROM plane_t
GROUP BY year;

# Using a Kafka Connect Connector not in Confluent Hub
This recipe will show how to use a Kafka Connect connector JAR which is not available in [Confluent Hub](https://www.confluent.io/hub). Popular connector not available there are the ones offered as the [Stream Reactor](https://github.com/lensesio/stream-reactor) project.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services KAFKA,KAFKA_CONNECT -s trivadis/platys-modern-data-platform -w 1.13.0
```
start the platform
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Download the Connector
Navigate into the kafka-connect folder
```bash
cd plugins/kafka-connect/connectors
```
and download the a conector JAR from the Landoop Stream-Reactor Project project (here we are using the MQTT connector, but it works in the same way for any other connector)
```bash
wget https://github.com/Landoop/stream-reactor/releases/download/2.1.3/kafka-connect-mqtt-2.1.3-2.5.0-all.tar.gz
```
Once it is successfully downloaded, uncompress it using this tar command and remove the file.
```bash
mkdir kafka-connect-mqtt-2.-2.1.0-all && tar xvf kafka-connect-mqtt-1.2.3-2.1.0-all.tar.gz -C kafka-connect-mqtt-1.2.3-2.1.0-all
rm kafka-connect-mqtt-1.2.3-2.1.0-all.tar.gz
```
Now let's restart Kafka connect in order to pick up the new connector.
```bash
cd ../..
docker-compose restart kafka-connect-1 kafka-connect-2
```
The connector has now been added to the Kafka cluster. You can confirm that by watching the log file of the two containers:
```
docker-compose logs -f kafka-connect-1 kafka-connect-2

# Spark with Apache Iceberg
This recipe will show how to use a Spark cluster together with the [Apache Iceberg](https://iceberg.apache.org) table format. We will be using the Python and SQL API.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services SPARK,ZEPPELIN,MINIO,AWSCLI,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.16.0
```
Before we can generate the platform, we need to extend the `config.yml`:
Specify the table format to use as Iceberg.
```
SPARK_table_format_type: 'iceberg'
```
Platys automatically makes sure that the right version according to [Using Iceberg in Spark 3](https://iceberg.apache.org/docs/latest/getting-started/#using-iceberg-in-spark-3) is used.
Now set an environment variable to the home folder of the dataplatform and generate and then start the data platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Prepare some data in Object storage
Create the flight bucket:
```bash
docker exec -ti awscli s3cmd mb s3://flight-bucket
```
Now upload the airports to the bucket
```bash
docker exec -ti awscli s3cmd put /data-transfer/flight-data/airports.csv s3://flight-bucket/raw/airports/airports.csv
```
## Working with Iceberg from Zeppelin
Navigate to Zeppelin <http://dataplatform:28080> and login as user `admin` with password `<PASSWORD>!`.
Create a new notebook and add and execute the following commands:
Import necessary modules
```python
%pyspark
from pyspark.sql.types import DoubleType, FloatType, LongType, StructType,StructField, StringType
```
Load the raw Airport data in the CSV format into a data frame
```python
%pyspark
airportsRawDF = spark.read.csv("s3a://flight-bucket/raw/airports",
sep=",", inferSchema="true", header="true")
airportsRawDF.show(5)
```
add
```python
%pyspark
airportsRawDF.withColumnRenamed('lat','latitude').withColumnRenamed('long','longitude').createOrReplaceTempView("airports_raw")
```
create a new Iceberg table, using the `CREATE TABLE` Spark SQL statement
```sql
%sql
CREATE TABLE iceberg.db.airports_t (iata string
, airport string
, city string
, state string
, country string
, latitude double
, longitude double)
USING ICEBERG;
```
Use the iceberg table in a SQL statement
```sql
%sql
SELECT * FROM iceberg.db.airports_t;
```
Append the raw data loaded before to the Iceberg table.
```python
%pyspark
airportsRawDF.withColumnRenamed('lat','latitude').withColumnRenamed('long','longitude').writeTo("iceberg.db.airports_t").append()
```
We have to rename the columns to fit with the structure of the table.
Now select the data again to check the update
```sql
%sql
SELECT * FROM airports_t;
```
We could have achieved the same using the following SQL INSERT statement
```sql
%sql
INSERT INTO iceberg.db.airports_t
SELECT iata, airport, city, state, country, latitude, longitude FROM airports_raw;
```
Instead of just appending data, we can also use a SQL MERGE to merge data from a source table into the target Iceberg table
```sql
%sql
MERGE INTO iceberg.db.airports_t t USING (SELECT * FROM airports_raw) u ON u.iata = t.iata
WHEN MATCHED THEN
UPDATE SET t.airport = u.airport, t.city = u.city, t.state = u.state, t.country = u.country, t.latitude = u.latitude, t.longitude = u.longitude
WHEN NOT MATCHED
THEN INSERT *
```

# Simulated Multi-DC Setup on one machine
This recipe will show how to setup a 2 datacenter Kafka platform on the same machine using docker compose and platys.
## Initialise data platform
We will create two different platforms, each one in its own directory, and configure them so that the service names are not overlapping.
### Data Center 1
Let's [initialise a platys-supported data platform](../../../documentation/getting-started) with the following services enabled
```bash
platys init --enable-services KAFKA,KAFKA_AKHQ -s trivadis/platys-modern-data-platform -w 1.14.0
```
Rename the `config.yml` file to include the datacenter (`dc1`)
```bash
mv config.yml config-dc1.yml
```
Edit the `config-dc1.yml` file and add the two global properties `data_centers` and `data_center_to_use` and change the header as shown below:
```
# Default values for the generator
# this file can be used as a template for a custom configuration
# or to know about the different variables available for the generator
platys:
platform-name: 'dc1-platform'
platform-stack: 'trivadis/platys-modern-data-platform'
platform-stack-version: '1.14.0'
structure: 'subfolder'
# ========================================================================
# Global configuration, valid for all or a group of services
# ========================================================================
# Timezone, use a Linux string such as Europe/Zurich or America/New_York
use_timezone: ''
# the name of the repository to use for private images, which are not on docker hub (currently only Oracle images)
private_docker_repository_name: 'trivadis'
data_centers: 'dc1,dc2'
data_center_to_use: 1
#
# ===== Apache Kafka ========
#
KAFKA_enable: true
#
# ===== Apache Kafka HQ ========
#
KAFKA_AKHQ_enable: true
```
The `data_center_to_use` property specifies that this configuration is for the first datacenter, which is named `dc1` by the `data_centers` list property.
Using `subfolder` for the `structure` will generate the platform inside a subfolder named according to the `platform-name`.
Generate the stack using the `-c` option to specify the config file to use
```bash
platys gen -c ${PWD}/config-dc1.yml
```
You should now have a subfolder named `dc1-platform`
```bash
docker@ubuntu:~/platys-cookbook$ ls -lsa
total 16
4 drwxrwxr-x 3 docker docker 4096 Dec 31 09:12 .
4 drwxr-xr-x 61 docker docker 4096 Dec 31 03:02 ..
4 -rwxr-xr-x 1 docker docker 1122 Dec 31 09:12 config-dc1.yml
4 drwxrwxr-x 12 docker docker 4096 Dec 31 09:12 dc1-platform
```
Navigate into this folder and start the stack for `dc1`
```bash
docker-compose -f dc1-platform/docker-compose.yml up -d
```
### Data Center 2
For data center 2, we could also go trough the `platys init` as before, but we can also just copy the configuration file and adapt it, like shown here
```bash
cp config-dc1.yml config-dc2.yml
```
now edit `config-dc2.yml` and change the property `platform-name` and `data_center_to_use` to specfiy data center 2:
```yaml
platys:
platform-name: 'dc2-platform'
...
data_center_to_use: 2
```
Generate the stack using the `-c` option to specify the config file to use
```bash
platys gen -c ${PWD}/config-dc2.yml
```
You should now have an additional subfolder named `dc2-platform`
```bash
docker@ubuntu:~/platys-cookbook$ ls -lsa
total 16
4 drwxrwxr-x 3 docker docker 4096 Dec 31 09:12 .
4 drwxr-xr-x 61 docker docker 4096 Dec 31 03:02 ..
4 -rwxr-xr-x 1 docker docker 1122 Dec 31 09:12 config-dc1.yml
4 -rwxr-xr-x 1 docker docker 1122 Dec 31 09:18 config-dc2.yml
4 drwxrwxr-x 12 docker docker 4096 Dec 31 09:12 dc1-platform
4 drwxrwxr-x 12 docker docker 4096 Dec 31 09:20 dc2-platform
```
Navigate into this folder and start the stack for `dc2`
```bash
docker-compose -f dc2-platform/docker-compose.yml up -d
```
We have now 2 different stacks running, each one representing one data center.
### Work with the two data centers and Kafka
Both stack have their own home page generated. You can find them on port `80` and `81`:
* **DC1**
* Homepage: <http://dataplatform:80>
* Service List: <http://dataplatform:80/services>
* **DC2**
* Homepage: <http://dataplatform:81>
* Service List: <http://dataplatform:81/services>
### Restrictions
Currently only [Zookeeper](../../../documentation/services/zookeeper), [Kafka Borker](../../../documentation/services/kafka), [Control Center](../../../documentation/services/confluent-control-center), [CMAK](../../../documentation/services/cmak), [AKHQ](../../../documentation/services/akhq) and [Wetty](../../../documentation/services/wetty) support to run in two different, simulated data centers. All the other services can still be used, but they should only be enabled in one of the two stacks. <file_sep># Apache Atlas

Navigate to <http://dataplatform:9411><file_sep># Using Kafka from Java with Protocol Buffers & Schema Registry
In this workshop we will learn how to produce and consume messages using the [Kafka Java API](https://kafka.apache.org/documentation/#api) using [Google Protocol Buffers](https://developers.google.com/protocol-buffers) for serialising and deserialising messages.
## Create the project in your Java IDE
Create a new Maven Project (using the functionality of your IDE) and in the last step use `com.trivadis.kafkaws` for the **Group Id** and `java-protobuf-kafka` for the **Artifact Id**.
Navigate to the **pom.xml** and double-click on it. The POM Editor will be displayed.
You can either use the GUI to edit your `pom.xml` or navigate to the last tab **pom.xml** to switch to the "code view". Let's do that.
You will see the still rather empty definition.
```xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>com.trivadis.kafkaws</groupId>
<artifactId>java-protobuf-kafka</artifactId>
<version>0.0.1-SNAPSHOT</version>
</project>
```
Let's add some initial dependencies for our project. We will add some more dependencies to the POM throughout this workshop.
Copy the following block right after the `<version>` tag, before the closing `</project>` tag.
```xml

## Create log4j settings
Let's also create the necessary log4j configuration.
In the code we are using the [Log4J Logging Framework](https://logging.apache.org/log4j/2.x/), which we have to configure using a property file.
Create a new file `log4j.properties` in the folder **src/main/resources** and add the following configuration properties.
```properties

```
## Creating the necessary Kafka Topic
We will use the topic `test-java-protobuf-topic` in the Producer and Consumer code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
In a terminal window, connect to the `kafka-1` container
```
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```
kafka-topics --create \
--replication-factor 3 \
--partitions 12 \
--topic test-java-protobuf-topic \
--bootstrap-server kafka-1:19092,kafka-2:19093
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing the **Kafka Producer** which uses Protocol Buffers for the serialisation.
## Create an Protocol Buffer Schema representing the Notification Message
First create a new Folder `protobuf` under the existing folder **src/main/**.
Create a new File `Notification-v1.proto` in the folder **src/main/protobuf** just created above.
Add the following Protocol Buffer schema to the empty file.
```
syntax = "proto3";
package com.trivadis.kafkaws.protobuf.v1;
option java_outer_classname = "NotificationProtos";
message Notification {
int64 id = 1;
string message = 2;
}
```
In the `pom.xml`, add the `protoc-jar-maven-plugin` plugin to the `<build><plugins>` section, just below the `exec-maven-plugin`.
```xml
<plugin>
<groupId>com.github.os72</groupId>
<artifactId>protoc-jar-maven-plugin</artifactId>
<version>3.11.4</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<inputDirectories>
<include>${project.basedir}/src/main/protobuf</include>
</inputDirectories>
<outputTargets>
<outputTarget>
<type>java</type>
<addSources>main</addSources>
<outputDirectory>${project.basedir}/target/generated-sources/protobuf</outputDirectory>
</outputTarget>
</outputTargets>
</configuration>
</execution>
</executions>
</plugin>
```
This plugin will make sure, that classes are generated based on the Protocol Buffer schema, whenever a `mvn compile` is executed. Execute the following command, to do that:
```
mvn compile
```
After running this command, refresh the project and you should see a new folder named `target/generated-sources/protobuf`. Expand into this folder and you should see one generated Java class named `NotificationProtos`.
Double click on the `NotificationProtos` class to inspect the code.
```java
package com.trivadis.kafkaws.protobuf.v1;
public final class NotificationProtos {
private NotificationProtos() {}
public static void registerAllExtensions(
com.google.protobuf.ExtensionRegistryLite registry) {
}
public static void registerAllExtensions(
com.google.protobuf.ExtensionRegistry registry) {
registerAllExtensions(
(com.google.protobuf.ExtensionRegistryLite) registry);
}
public interface NotificationOrBuilder extends
// @@protoc_insertion_point(interface_extends:com.trivadis.kafkaws.protobuf.v1.Notification)
com.google.protobuf.MessageOrBuilder {
/**
* <code>int64 id = 1;</code>
* @return The id.
*/
long getId();
/**
* <code>string message = 2;</code>
* @return The message.
*/
java.lang.String getMessage();
/**
* <code>string message = 2;</code>
* @return The bytes for message.
*/
com.google.protobuf.ByteString
getMessageBytes();
}
...
```
You can see that the code is based on the information in the Protobuf schema. We will use this class when we produce and consume Protocol Buffer messages to/from Kafka.
## Create a Kafka Producer using Protocol Buffers for serialisation
First create a new Java Package `com.trivadis.kafkaws.producer` in the folder **src/main/java**.
Create a new Java Class `KafkaProducerProtobuf` in the package `com.trivadis.kafakws.producer` just created.
Add the following code to the empty class to create a Kafka Producer. It is similar to the code we have seen in the previous workshop. We have changed both the key and the value serialier to use the Confluent `KafkaProtobufSerializer` class and added the URL to the Confluent Schema Registry API.
```java
package com.trivadis.kafkaws.producer;
import com.trivadis.kafkaws.protobuf.v1.NotificationProtos.Notification;
import io.confluent.kafka.serializers.protobuf.KafkaProtobufSerializer;
import io.confluent.kafka.serializers.protobuf.KafkaProtobufSerializerConfig;
import org.apache.kafka.clients.producer.*;
import java.util.Properties;
public class KafkaProducerProtobuf {
private final static String TOPIC = "test-java-protobuf-topic";
private final static String BOOTSTRAP_SERVERS =
"dataplatform:9092, dataplatform:9093, dataplatform:9094";
private final static String SCHEMA_REGISTRY_URL = "http://dataplatform:8081";
private static Producer<Long, Notification> createProducer() {
Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ProducerConfig.CLIENT_ID_CONFIG, "KafkaExampleProducer");
//props.put(KafkaProtobufSerializerConfig.AUTO_REGISTER_SCHEMAS, "false");
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, KafkaProtobufSerializer.class.getName());
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, KafkaProtobufSerializer.class.getName());
props.put(KafkaProtobufSerializerConfig.SCHEMA_REGISTRY_URL_CONFIG, SCHEMA_REGISTRY_URL); // use constant for "schema.registry.url"
return new KafkaProducer<>(props);
}
}
```
We will be using the synchronous way for producing messages to the Kafka topic we created above, but the other methods would work as well with Protobuf.
```java
static void runProducer(final int sendMessageCount, final int waitMsInBetween, final long id) throws Exception {
final Producer<Long, Notification> producer = createProducer();
long time = System.currentTimeMillis();
Long key = (id > 0) ? id : null;
try {
for (long index = 0; index < sendMessageCount; index++) {
Notification notification = Notification.newBuilder().setId(id).setMessage("Hello Kafka " + index).build();
final ProducerRecord<Long, Notification> record =
new ProducerRecord<>(TOPIC, key, notification);
RecordMetadata metadata = producer.send(record).get();
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) " +
"meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
time = System.currentTimeMillis();
Thread.sleep(waitMsInBetween);
}
} finally {
producer.flush();
producer.close();
}
}
```
Next you define the main method.
```
public static void main(String... args) throws Exception {
if (args.length == 0) {
runProducer(100,10,0);
} else {
runProducer(Integer.parseInt(args[0]),Integer.parseInt(args[1]),Long.parseLong(args[2]));
}
}
```
The `main()` method accepts 3 parameters, the number of messages to produce, the time in ms to wait in-between sending each message and the ID of the producer.
Use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-java-protobuf-topic `.
```
kcat -b kafka-1:19092 -t test-java-protobuf-topic
```
Now run it using the `mvn exec:java` command. It will generate 1000 messages, waiting 10ms in-between sending each message and use 0 for the ID.
```
mvn exec:java@producer -Dexec.args="1000 10 0"
```
You can see that kafkacat shows some special, non-printable characters. This is due to the Protocol Buffer format. If you want to display the Protocol Buffer in a readable way, you can use the `kafka-protobuf-console-consumer` CLI, which is part of the Schema Registry.
So let's connect to the schema registry container:
```
docker exec -ti schema-registry-1 bash
```
And then invoke the `kafka-protobuf-console-consumer` similar to the "normal" consumer seen so far.
```
kafka-protobuf-console-consumer --bootstrap-server kafka-1:19092 --topic test-java-protobuf-topic
```
You should see an output similar to the one below.
```
...

Consuming with `kcat` and specifying the serialisation format `-s` and the address of the schema registry `-r` does not yet work for Protocol Buffers, it only works for Avro.
**Note:** There is an [open ticket](https://github.com/edenhill/kcat/issues/353) to add Protobuf support to `kcat`.
## View the Schema in the Registry
The Protobuf Serializer and Deserializer automatically register the Protocol Buffer schema, if it is not already in the registry.
The Streamingplatform also contains a tool made by a company called Landoop which allows us to see what's in the registry. But it does not support Protocol Buffer schemas! But we can use [AKHQ](https://akhq.io/) to view the schema registry.
In a browser, navigate to <http://dataplatform:28107> and navigate to the **Schema Registry** menu item on the left.
Click on the hourglass icon on the schema to view the details of the schema
## Create a Kafka Consumer using Protobuf for serialisation
First create a new Java Package `com.trivadis.kafkaws.consumer` in the folder **src/main/java**.
Create a new Java Class `KafkaConsumerProtobuf` in the package `com.trivadis.kafakws.consumer` just created.
Add the following code to the empty class.
```java
package com.trivadis.kafkaws.consumer;
import com.trivadis.kafkaws.protobuf.v1.NotificationProtos.Notification;
import io.confluent.kafka.serializers.protobuf.KafkaProtobufDeserializer;
import io.confluent.kafka.serializers.protobuf.KafkaProtobufDeserializerConfig;
import org.apache.kafka.clients.consumer.Consumer;
import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.KafkaConsumer;
import java.util.Collections;
import java.util.Properties;
public class KafkaConsumerProtobuf {
private final static String TOPIC = "test-java-protobuf-topic";
private final static String BOOTSTRAP_SERVERS =
"dataplatform:9092, dataplatform:9093, dataplatform:9094";
private final static String SCHEMA_REGISTRY_URL = "http://dataplatform:8081";
private static Consumer<Long, Notification> createConsumer() {
final Properties props = new Properties();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ConsumerConfig.GROUP_ID_CONFIG, "KafkaConsumerProtobuf");
props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, false);
props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, 10000);
props.put(KafkaProtobufDeserializerConfig.AUTO_REGISTER_SCHEMAS, "false");
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, KafkaProtobufDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, KafkaProtobufDeserializer.class.getName());
props.put(KafkaProtobufDeserializerConfig.SCHEMA_REGISTRY_URL_CONFIG, SCHEMA_REGISTRY_URL); // use constant for "schema.registry.url"
// Create the consumer using props.
final Consumer<Long, Notification> consumer =
new KafkaConsumer<>(props);
// Subscribe to the topic.
consumer.subscribe(Collections.singletonList(TOPIC));
return consumer;
}
static void runConsumer(int waitMsInBetween) throws InterruptedException {
final Consumer<Long, Notification> consumer = createConsumer();
final int giveUp = 100;
int noRecordsCount = 0;
while (true) {
final ConsumerRecords<Long, Notification> consumerRecords = consumer.poll(1000);
if (consumerRecords.count()==0) {
noRecordsCount++;
if (noRecordsCount > giveUp)
break;
}
consumerRecords.forEach(record -> {
System.out.printf("%d - Consumer Record:(Key: %d, Value: %s, Partition: %d, Offset: %d)\n",
consumerRecords.count(), record.key(), record.value(),
record.partition(), record.offset());
try {
Thread.sleep(waitMsInBetween);
} catch (InterruptedException e) {
}
});
consumer.commitSync();
}
consumer.close();
System.out.println("DONE");
}
public static void main(String... args) throws Exception {
if (args.length == 0) {
runConsumer(10);
} else {
runConsumer(Integer.parseInt(args[0]));
}
}
}
```
## Register in Schema Registry using Maven
In the test above, the Protocol Buffer schema has been registered in the schema registry when starting the Producer for the first time. To register a Protocol Buffer schema through Maven automatically, you can use the `kafka-schema-registry-maven-plugin` Maven plugin.
Add the following definition to the `pom.xml`.
```xml
<plugin>
<groupId>io.confluent</groupId>
<artifactId>kafka-schema-registry-maven-plugin</artifactId>
<version>7.0.0</version>
<configuration>
<schemaRegistryUrls>
<param>http://${DATAPLATFORM_IP}:8081</param>
</schemaRegistryUrls>
<schemaTypes>
<test-java-protobuf-topic-value>PROTOBUF</test-java-protobuf-topic-value>
</schemaTypes>
<subjects>
<test-java-protobuf-topic-value>src/main/protobuf/Notification-v1.proto</test-java-protobuf-topic-value>
</subjects>
</configuration>
<goals>
<goal>register</goal>
<goal>test-compatibility</goal>
</goals>
</plugin>
```
Now you can use the following command to register the schemas with the Schema Registry:
```
mvn schema-registry:register
```

To install Java 11 perform
```bash
sudo yum update
sudo yum install java-11-openjdk
sudo yum install java-11-openjdk-devel
```
and then activate the Java 11 environment by executing
```bash
sudo update-alternatives --config 'java'
sudo update-alternatives --config 'javac'
```
select both time the Java 11 environment and then test if Java 11 is used
```bash
java -version
javac -version
```
### Installing Maven 3.6.3
Download and install Maven 3.6.3
```bash
wget https://mirrors.estointernet.in/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
tar -xvf apache-maven-3.6.3-bin.tar.gz
sudo mv apache-maven-3.6.3 /opt/
```
Add the following 3 lines to the end of `.bash_profile`
```bash
M2_HOME=/opt/apache-maven-3.6.3
PATH="$M2_HOME/bin:$PATH"
export PATH
```
No source `.bash_profile` and then test that the new version of Maven is used
```bash

# NiFi Registry with Git Flow Persistence Provider
This recipe will show how to use [NiFi Registry](https://nifi.apache.org/registry.html) with the [Git Flow Persistence Provider](https://nifi.apache.org/docs/nifi-registry-docs/html/administration-guide.html#gitflowpersistenceprovider) enabled. We will show various configurations and their behaviour.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```bash
export DATAPLATFORM_HOME=${PWD}
platys init --enable-services NIFI,NIFI_REGISTRY -s trivadis/platys-modern-data-platform -w 1.16.0
```
Before we can generate the platform, we need to create a Git Repository and extend the `config.yml` with the necessary configuration.
## Create a Git Repository
Create a new Git repository which will be used as the storage for the Flow Persistence. In this cookbook we will assume that the repository is named `nifi-git-flow-provider`.
## Using Git Flow Persistence Provider without automatic Push
Enable authentication by adding the following settings to the `config.yml`
```yaml
NIFI_REGISTRY_volume_map_flow_storage: true
NIFI_REGISTRY_flow_provider: git
NIFI_REGISTRY_git_user: gschmutz
NIFI_REGISTRY_git_repo: http://github.com/<owner>/nifi-git-flow-provider
NIFI_REGISTRY_flow_storage_folder_on_dockerhost: ./nifi-git-flow-provider
```
The password could also be specified using the `NIFI_REGISTRY_git_password` configuration setting. But to avoid it ending up in the `docker-compose.yml` file, we rather use the option to add it as an environment variable:
Create a `.env` file
```
nano .env
```
and add the following environment variable to specify the password for the Git Repo
```bash
PLATYS_NIFI_REGISTRY_GIT_PASSWORD=<PASSWORD>
```
Save the file and generate and start the data platform.
```bash
platys gen
docker-compose up -d
```
Now let's use NiFi together with the Registry. Here we will only show the most important steps, you can find a more tutorial like documentation [here](https://nifi.apache.org/docs/nifi-registry-docs/index.html).
Navigate to the NiFi Registry: <http://dataplatform:19090/nifi-registry> and create a new bucket and name it `my-bucket`.
Navigate to NiFi <https://dataplatform:18080> and login as user `nifi` with password `<PASSWORD>`.
Click on the Sandwich menu in the top right and open **Controller Settings**. Navigate to the **Registry Clients** tab and add a new Registry Client.
Click **Add** and then edit the client and set the **URL** of the NiFi Registry to `http://nifi-registry:19090` and click on **UPDATE**.
Now with the link to NiFi Registry configured, we can start using it.
Add a new **Process Group** to the NiFi canvas. Right click on the process group and select **Version** | **Start version control** to add it to version control.
Add the information to the **Save Flow Version** screen and hit **SAVE**.
You now have a process group which is under version control, shown by the green checkmark in the top left corner.
If you want the NiFi Registry to automatically push changes to the remote
## Using Git Flow Persistence Provider with automatic Push
Enable authentication by adding the following settings to the `config.yml`
```yaml
NIFI_REGISTRY_flow_provider: git
NIFI_REGISTRY_git_remote: origin
NIFI_REGISTRY_git_user: gschmutz
NIFI_REGISTRY_git_repo: http://github.com/<owner>/nifi-git-flow-provider
NIFI_REGISTRY_flow_storage_folder_on_dockerhost: ./nifi-git-flow-provider

## How to enable?
```
platys init --enable-services TRINO
platys gen
```
## How to use it?
Navigate to <http://dataplatform:28082>
To connect over the CLI, use:
```
docker exec -it trino-cli trino --server trino-1:8080
```
if authentication is enabled (`TRINO_auth_enabled`), then you have to connect over `https` and specify the user and the keystore:
```
docker exec -it trino-cli trino --server https://trino-1:8443 --user admin --password --insecure --keystore-path /etc/trino/trino.jks --keystore-password <PASSWORD>!
```
### Security
Security for Trino can be enabled with `TRINO_auth_enabled` (to enable authentication) and `TRINO_access_control_enabled` (to enable access control).
#### Authentication
By default the following 3 users and passwords are pre-configured:
1. `admin` : `<PASSWORD>!`
2. `userA` : `<PASSWORD>!`
3. `userB` : `<PASSWORD>!`
You can specify your own password file in `conf/trino/security/password.db` by enabling `TRINO_auth_use_custom_password_file`. See [here](https://trino.io/docs/current/security/password-file.html#creating-a-password-file) for how to add users to the password file.
You can also create groups by enabling `TRINO_auth_with_groups` and specifying them in `custom-conf/trino/security/group.txt`.
#### Access Control
Enable access control with `TRINO_access_control_enabled` and set the access control rules in `custom-conf/trino/security/rules.json`.

This table reserves the external ports for the various services. Not all services have to be used in the platform at a given time. But by reserving, we can assure that there are no conflicts if a service is added at a later time.

# Using Jupyter notebook with Spark and Avro
This recipe will show how to use Jupyter with the local Spark engine and working with Avro data. By that we also show how to specify an additional dependency (to Avro).
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services JUPYTER,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.16.0
```
Edit the `config.yml` and add the following properties after `JUPYTER_enable`
```yaml
JUPYTER_edition: 'all-spark'
JUPYTER_spark_jars_packages: 'org.apache.spark:spark-avro_2.12:3.1.1'
JUPYTER_tokenless: false
JUPYTER_token: '<PASSWORD>!'
```
We specify the `all-spark` edition of Jupyter and specify the dependency on `org.apache.spark:spark-avro_2.12:3.1.1` to be added to the Spark environment. This will automatically be added to `spark-defaults.conf` when starting Jupyter.
Additionally we specify the token to login into Jupyter as `<PASSWORD>!`.
Generate and start the platform
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
The `PROVISIONING_DATA_enable` setting will copy data to the `data-transfer` folder. We will use from `flight-data` folder the `airports.avro` file.
```
docker@ubuntu ~/platys-demo [SIGINT]> ls -lsa data-transfer/flight-data/
total 57056

948 -rw-r--r-- 1 root root 968807 Oct 3 10:26 plane-data.json
```
## Using Jupyter to read the Airports.avro file
Navigate to Jupyter on <http://dataplatform:28888>.
Enter `<PASSWORD>!` into the **Password or token** field and click on **Log in**:
On the **Launcher** page, click on **Python 3** Notebook.
Add the following block as the first cell
```python
import os
# make sure pyspark tells workers to use python3 not 2 if both are installed
#os.environ['PYSPARK_PYTHON'] = '/usr/bin/python3'
import pyspark
conf = pyspark.SparkConf()
from pyspark.sql import SparkSession
spark = SparkSession.builder.appName('abc').config(conf=conf).getOrCreate()
sc = spark.sparkContext
```
and execute it.
If you check the Jupyter log using `docker log -f jupyter` you can see that the avro jar has been downloaded:
```bash
docker logs -f jupyter
Set username to: jovyan
usermod: no changes

# Neo4J and yFiles graphs for Jupyter
This recipe will show how to use a Neo4j with the [jFiles Graph for Jupyter](https://www.yworks.com/products/yfiles-graphs-for-jupyter) to visualize graph networks with Python.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services NEO4J,JUPYTER -s trivadis/platys-modern-data-platform -w 1.16.0
```
Before we can generate the platform, we need to extend the `config.yml`:
Add the required python modules to `JUPYTER_python_packages`
```yaml
JUPYTER_python_packages: 'yfiles_jupyter_graphs neo4j ipywidgets'
```
and also add a custom token
```yaml
JUPYTER_token: '<PASSWORD>!'
```
Now set an environment variable to the home folder of the dataplatform and generate and then start the data platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Load a database into Neo4J
Navigate to <http://dataplatform:7474> and login as user `neo4j` and password `<PASSWORD>`.
Now load the movie graph by executing
```
:PLAY movie graph
```
on the resulting cell, navigate to page **2/8** and click on the play icon in the Cypher statement to execute it.
The movie database is loaded into Neo4j.
## Using yFiles Graph from Jupyter
Navigate to <http://dataplatform:28888> and login with the token specified above, i.e. `<PASSWORD>!`.
Create a new notebook and add and execute the following cells:
First let's specify the login config
```cypher
from neo4j import basic_auth
db = "bolt://neo4j-1:7687"
auth = basic_auth("neo4j", "<PASSWORD>")
```
Now connect to the database
```cypher
from neo4j import GraphDatabase
driver = GraphDatabase.driver(db, auth=auth)
session = driver.session()
```
And execute a query against the database and visualize it
```cypher
result = session.run("MATCH (s)-[r]->(t) RETURN s,r,t LIMIT 20")
from yfiles_jupyter_graphs import GraphWidget
w = GraphWidget(graph = result.graph())
w.show()
```
you should see the following output in Jupyter

This document describes how to install the workshop environment on a Ubuntu Machine, which could be running in a virtual machine, either in the cloud, on a remote server or on your local machine.
The VM should be configured with at least 8 GB and 4 CPUs.
## Setup Software
First let's create some environment variables.
```bash
export GITHUB_PROJECT=kafka-workshop
export GITHUB_OWNER=gschmutz
export DATAPLATFORM_HOME=01-environment/docker
export PLATYS_VERSION=2.4.3
export NETWORK_NAME=<network-name>
```
**Note:** Make sure to replace the `<network-name>` by the value retrieved from `ip addr`, which would be `ens33` in the example below
```
$ ip addr
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:0c:29:3a:82:45 brd ff:ff:ff:ff:ff:ff
altname enp2s1
```
### Install some helpful utilities
```bash
sudo apt-get install -y curl jq kafkacat openssh-server
```
### Installing Docker
The instructions below are taken from here: <https://docs.docker.com/engine/install/ubuntu/>
**Setup the repository**
Uninstall old versions
```bash
sudo apt-get remove docker docker-engine docker.io containerd runc
```
Update `apt` package index and install packages
```bash
sudo apt-get update
sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release
```
Add Docker's official GPG key
```bash
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
```
Setup the repository
```bash
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
```
**Install Docker Engine**
Update the apt package index, and install the latest version of Docker Engine, containerd, and Docker Compose
```bash
sudo apt-get update
```
**Note:** if you receive a GPG error when running apt-get update
```bash
sudo chmod a+r /etc/apt/keyrings/docker.gpg
sudo apt-get update
```
Now install the latest version of Docker
```bash
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
```
**Add user to `docker` group**
```bash
sudo usermod -aG docker $USER
```
logout and relogin as the user.
**Test if docker is working**
```bash
docker -v
docker ps
```
### Installing Docker Compose Switch
[Compose Switch](https://github.com/docker/compose-switch) is a replacement to the Compose V1 docker-compose (python) executable.
Download compose-switch binary for your architecture:
```bash
sudo curl -fL https://github.com/docker/compose-switch/releases/latest/download/docker-compose-linux-amd64 -o /usr/local/bin/compose-switch
```
Make compose-switch executable:
```bash
sudo chmod +x /usr/local/bin/compose-switch
```
Define an "alternatives" group for docker-compose command
```
sudo update-alternatives --install /usr/local/bin/docker-compose docker-compose /usr/local/bin/compose-switch 99
```
### Installing Platys
Installing `platys` is optional. It is an [open source tool](http://github.com/trivadispf/platys) we have used to generate the docker-compose stack we will use below.
```bash
sudo curl -L "https://github.com/TrivadisPF/platys/releases/download/2.4.3/platys_2.4.3_linux_x86_64.tar.gz" -o /tmp/platys.tar.gz
tar zvxf /tmp/platys.tar.gz
sudo mv platys /usr/local/bin/
sudo chown root:root /usr/local/bin/platys
sudo rm README.md
```
Test that `platys` is working
```bash
platys -v
```
## Prepare Environment
In a terminal terminal window execute the following commands.
### Setup environment variables
If your virtual machine is running in the cloud or on a remote server, set the `PUBLIC_IP` variable to the IP Address you use to reach it
```bash
export PUBLIC_IP=<public-ip>
```
otherwise this command (make sure that `$NETWORK_NAME` has been set correctly)
```bash
export PUBLIC_IP=$(ip addr show $NETWORK_NAME | grep "inet\b" | awk '{print $2}' | cut -d/ -f1)
```
Additionally set the `DOCKER_HOST_IP` to the IP address of the machine (make sure that `$NETWORK_NAME` has been set correctly)
```bash
export DOCKER_HOST_IP=$(ip addr show $NETWORK_NAME | grep "inet\b" | awk '{print $2}' | cut -d/ -f1)
```
### Clone Workshop GitHub project
Now let's clone the Kafka Workshop project from GitHub:
```
cd
git clone https://github.com/${GITHUB_OWNER}/${GITHUB_PROJECT}.git
cd ${GITHUB_PROJECT}/${DATAPLATFORM_HOME}
export DATAPLATFORM_HOME=$PWD
```
### Persist Environment variables
Finally let's persist the 3 environment variables `PUBLIC_IP`, `DOCKER_HOST_IP` and `DATAPLATFORM_HOME`, so that they are available after a logout.
```bash
printf "export PUBLIC_IP=$PUBLIC_IP\n" >> /home/$USER/.bash_profile
printf "export DOCKER_HOST_IP=$DOCKER_HOST_IP\n" >> /home/$USER/.bash_profile
printf "export DATAPLATFORM_HOME=$DATAPLATFORM_HOME\n" >> /home/$USER/.bash_profile
printf "\n" >> /home/$USER/.bash_profile
sudo chown ${USER}:${USER} /home/$USER/.bash_profile
```
### Settings for Elasticsearch
For Elasticsearch to run properly, we have to increase the `vm.max_map_count` parameter like shown below.
```bash
sudo sysctl -w vm.max_map_count=262144
```
## Start Environment
Start the environment by performing a `docker-compose up`
```
docker-compose up -d
```
If started the first time, the necessary docker images will be downloaded from the public docker registry. Therefore you need internet access from your machine.
Depending on the speed of the network, the download takes a few minutes (around 5 minutes).
Once this is done, the docker container will start one by one, and at the end the output should be similar to the one below.
Your instance is now ready to use. Complete the post installation steps documented the [here](README.md).
In a web browser navigate to `http://<public-ip>` to access the markdown page with the relevant information about the docker compose stack.
Click on link **All available services which are part of the platform are listed here** to navigate to the list of services:
## Stop environment
To stop the environment, execute the following command:
```
docker-compose stop
```
after that it can be re-started using `docker-compose start`.
## Remove the environment
To stop and remove all running container, execute the following command:
```
docker-compose down
```

# Using MLflow from Jupyter
This recipe will show how to use MLflow from Jupyter. We will be using the [Elastic Net example](https://github.com/mlflow/mlflow/tree/master/examples/sklearn_elasticnet_wine) from the MLFlow [Tutorials and Examples](https://mlflow.org/docs/latest/tutorials-and-examples/index.html) page.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```bash
platys init --enable-services MLFLOW_SERVER,MINIO,JUPYTER -s trivadis/platys-modern-data-platform -w 1.16.0
```
add to `config.yml`
```yaml
JUPYTER_edition: 'datascience'
JUPYTER_python_packages: 'mlflow'
JUPYTER_token: 'abc123!'
```
Now generate and start the platform
```bash
platys gen
docker-compose up -d
```
## Working with MLflow
Navigate to Jupyter on <http://dataplatform:28888>.
Create a new notebook and add the following cell
```python
# Wine Quality Sample
def train(in_alpha, in_l1_ratio):
import os
import warnings
import sys
import pandas as pd
import numpy as np
from sklearn.metrics import mean_squared_error, mean_absolute_error, r2_score
from sklearn.model_selection import train_test_split
from sklearn.linear_model import ElasticNet
import mlflow
import mlflow.sklearn
import logging
logging.basicConfig(level=logging.WARN)
logger = logging.getLogger(__name__)
def eval_metrics(actual, pred):
rmse = np.sqrt(mean_squared_error(actual, pred))
mae = mean_absolute_error(actual, pred)
r2 = r2_score(actual, pred)
return rmse, mae, r2
warnings.filterwarnings("ignore")
np.random.seed(40)
# Read the wine-quality csv file from the URL
csv_url = (
"http://archive.ics.uci.edu/ml/machine-learning-databases/wine-quality/winequality-red.csv"
)
try:
data = pd.read_csv(csv_url, sep=";")
except Exception as e:
logger.exception(
"Unable to download training & test CSV, check your internet connection. Error: %s", e
)
# Split the data into training and test sets. (0.75, 0.25) split.
train, test = train_test_split(data)
# The predicted column is "quality" which is a scalar from [3, 9]
train_x = train.drop(["quality"], axis=1)
test_x = test.drop(["quality"], axis=1)
train_y = train[["quality"]]
test_y = test[["quality"]]
# Set default values if no alpha is provided
if float(in_alpha) is None:
alpha = 0.5
else:
alpha = float(in_alpha)
# Set default values if no l1_ratio is provided
if float(in_l1_ratio) is None:
l1_ratio = 0.5
else:
l1_ratio = float(in_l1_ratio)
# Useful for multiple runs (only doing one run in this sample notebook)
with mlflow.start_run():
# Execute ElasticNet
lr = ElasticNet(alpha=alpha, l1_ratio=l1_ratio, random_state=42)
lr.fit(train_x, train_y)
# Evaluate Metrics
predicted_qualities = lr.predict(test_x)
(rmse, mae, r2) = eval_metrics(test_y, predicted_qualities)
# Print out metrics
print("Elasticnet model (alpha=%f, l1_ratio=%f):" % (alpha, l1_ratio))
print(" RMSE: %s" % rmse)
print(" MAE: %s" % mae)
print(" R2: %s" % r2)
# Log parameter, metrics, and model to MLflow
mlflow.log_param("alpha", alpha)
mlflow.log_param("l1_ratio", l1_ratio)
mlflow.log_metric("rmse", rmse)
mlflow.log_metric("r2", r2)
mlflow.log_metric("mae", mae)
mlflow.sklearn.log_model(lr, "model")
```
Now let's invoke it with different parameters
```python
train(0.5, 0.5)
```
```python
train(0.2, 0.2)
```
```python
train(0.1, 0.1)
```

In this workshop we will see various CDC solutions in action
1. Polling-based CDC using Kafka Connect
2. Log-based CDC using Debezium and Kafka Connect
3. Transactional Outbox Pattern using Debezium and Kafka Connect
## Creating Postgresql Database `cdc_demo `
The `driver` table holds the information of the drivers working for us. Let's connect to the postgresql database running as part of the dataplatform and create the table
```bash
docker exec -ti postgresql psql -d postgres -U postgres
```
If the table is not available, this is the code to run
```sql
CREATE SCHEMA IF NOT EXISTS cdc_demo;
SET search_path TO cdc_demo;
DROP TABLE IF EXISTS address;
DROP TABLE IF EXISTS person;
CREATE TABLE "cdc_demo"."person" (
"id" integer NOT NULL,
"title" character varying(8),
"first_name" character varying(50),
"last_name" character varying(50),
"email" character varying(50),
"modifieddate" timestamp DEFAULT now() NOT NULL,
CONSTRAINT "person_pk" PRIMARY KEY ("id")
);
CREATE TABLE "cdc_demo"."address" (
"id" integer NOT NULL,
"person_id" integer NOT NULL,
"street" character varying(50),
"zip_code" character varying(10),
"city" character varying(50),
"modifieddate" timestamp DEFAULT now() NOT NULL,
CONSTRAINT "address_pk" PRIMARY KEY ("id")
);
ALTER TABLE ONLY "cdc_demo"."address" ADD CONSTRAINT "address_person_fk" FOREIGN KEY (person_id) REFERENCES person(id) NOT DEFERRABLE;
```
## Polling-based CDC using Kafka Connect
In this section we will see how we can use the [JDBC Source Connector](https://www.confluent.io/hub/confluentinc/kafka-connect-jdbc) to perform polling-based CDC on the two tables.
To use the Polling-based CDC with Kafka Connect, we have to install the [JDBC Source Connector](https://www.confluent.io/hub/confluentinc/kafka-connect-jdbc) on our Kafka Connect cluster.
On the workshop environment, this has already been done. You can check the available connectors either from [Kafka Connect UI](http://dataplatform:28103/#/cluster/kafka-connect-1/select-connector) or by using the REST API `curl -XGET http://$DOCKER_HOST_IP:8083/connector-plugins | jq`
#### Create the necessary topics
Let's create a topic for the change records of the two tables 'person` and `address`:
```bash
docker exec -ti kafka-1 kafka-topics --bootstrap-server kafka-1:19092 --create --topic priv.person.cdc.v1 --partitions 8 --replication-factor 3
docker exec -ti kafka-1 kafka-topics --bootstrap-server kafka-1:19092 --create --topic priv.address.cdc.v1 --partitions 8 --replication-factor 3
```
Now let's start two consumers, one on each topic, in separate terminal windows
```bash
kcat -b kafka-1:19092 -t priv.person.cdc.v1 -f '[%p] %k: %s\n' -q
```
```bash
kcat -b kafka-1:19092 -t priv.address.cdc.v1 -f '[%p] %k: %s\n' -q
```
By using the `-f` option we tell `kcat` to also print the partition number and the key for each message.
#### Create some initial data in Postgresql
Let's add a first person and address as a sample. In a terminal connect to Postgresql
```bash
docker exec -ti postgresql psql -d postgres -U postgres
```
execute the following SQL INSERT statements
```sql
INSERT INTO cdc_demo.person (id, title, first_name, last_name, email)
VALUES (1, 'Mr', 'Peter', 'Muster', '<EMAIL>');
INSERT INTO cdc_demo.address (id, person_id, street, zip_code, city)
VALUES (1, 1, 'Somestreet 10', '9999', 'Somewhere');
```
#### Create a JDBC Source connector instance
Now let's create and start the JDBC Source connector
```bash
curl -X "POST" "$DOCKER_HOST_IP:8083/connectors" \
-H "Content-Type: application/json" \
-d $'{
"name": "person.jdbcsrc.cdc",
"config": {
"connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector",
"tasks.max": "1",
"connection.url":"jdbc:postgresql://postgresql/postgres?user=postgres&password=<PASSWORD>!",
"mode": "timestamp",
"timestamp.column.name":"modifieddate",
"poll.interval.ms":"10000",
"table.whitelist":"cdc_demo.person,cdc_demo.address",
"validate.non.null":"false",
"topic.prefix":"priv.",
"key.converter":"org.apache.kafka.connect.storage.StringConverter",
"key.converter.schemas.enable": "false",
"value.converter":"org.apache.kafka.connect.json.JsonConverter",
"value.converter.schemas.enable": "false",
"name": "person.jdbcsrc.cdc",
"transforms":"createKey,extractInt,addSuffix",
"transforms.createKey.type":"org.apache.kafka.connect.transforms.ValueToKey",
"transforms.createKey.fields":"id",
"transforms.extractInt.type":"org.apache.kafka.connect.transforms.ExtractField$Key",
"transforms.extractInt.field":"id",
"transforms.addSuffix.type":"org.apache.kafka.connect.transforms.RegexRouter",
"transforms.addSuffix.regex":".*",
"transforms.addSuffix.replacement":"$0.cdc.v1"
}
}'
```
You can find the documentation on the configuration settings [here](https://docs.confluent.io/kafka-connect-jdbc/current/source-connector/source_config_options.html).
After a maximum of 10 seconds (which is the polling interval we set), we should see one message each in the two topic, one for the record in the `person` and one for the record in the `address` table.
You can also monitor the connector in the Kafka Connect UI: <http://dataplatform:28103/>
#### Configuration options
Let's discuss some of the configurations in the connector.
The key get's extracted using two [Single Message Transforms (SMT)](https://docs.confluent.io/platform/current/connect/transforms/overview.html), the `ValueToKey` and the `ExtractField`. They are chained together to set the key for data coming from a JDBC Connector. During the transform, `ValueToKey` copies the message id field into the message key and then `ExtractField` extracts just the integer portion of that field.
```json
"transforms.createKey.type":"org.apache.kafka.connect.transforms.ValueToKey",
"transforms.createKey.fields":"id",
"transforms.extractInt.type":"org.apache.kafka.connect.transforms.ExtractField$Key",
"transforms.extractInt.field":"id",
```
To also add a suffix to the topic (we have added a prefix using the `topic.prefix` configuration) we can use the `RegexRouter` SMT
```json
"transforms.addSuffix.type":"org.apache.kafka.connect.transforms.RegexRouter",
"transforms.addSuffix.regex":".*",
"transforms.addSuffix.replacement":"$0.cdc.v1"
```
#### Add more data
Let's add some more data to the tables and check how quick the data will appear in the topics.
In a new terminal window, again connect to postgresql
```bash
docker exec -ti postgresql psql -d postgres -U postgres
```
Add a new `address` to `person` with `id=1`.
```sql
INSERT INTO cdc_demo.address (id, person_id, street, zip_code, city)
VALUES (2, 1, 'Holiday 10', '1999', 'Ocean Somewhere');
```
Now let's add a new `person`, first without an `address`
```sql
INSERT INTO cdc_demo.person (id, title, first_name, last_name, email)
VALUES (2, 'Ms', 'Karen', 'Muster', '<EMAIL>');
```
and now also add the `address`
```sql
INSERT INTO cdc_demo.address (id, person_id, street, zip_code, city)
VALUES (3, 2, 'Somestreet 10', '9999', 'Somewhere');
```
#### Remove the connector
We have successfully tested the query-based CDC using the JDBC Source connector. So let's remove the connector.
```bash
curl -X "DELETE" "http://$DOCKER_HOST_IP:8083/connectors/person.jdbcsrc.cdc"
```
## Log-based CDC using Debezium and Kafka Connect
In this section we will see how we can use [Debezium](https://debezium.io/) and it's Postgresql connector to perform log-based CDC on the two tables.
The [Debezium connector](https://www.confluent.io/hub/debezium/debezium-connector-postgresql) comes pre-installed with the Dataplatform stack.
#### Create some initial data in Postgresql
Let's add a first person and address as a sample. In a terminal connect to Postgresql
```bash
docker exec -ti postgresql psql -d postgres -U postgres
```
and execute the following SQL TRUNCATE followed by INSERT statements
```sql
TRUNCATE cdc_demo.person CASCADE;
INSERT INTO cdc_demo.person (id, title, first_name, last_name, email)
VALUES (1, 'Mr', 'Peter', 'Muster', '<EMAIL>');
INSERT INTO cdc_demo.address (id, person_id, street, zip_code, city)
VALUES (1, 1, 'Somestreet 10', '9999', 'Somewhere');
```
#### Create the Debezium connector
Now with the connector installed and the Kafka Connect cluster restarted, let's create and start the connector:
```bash
curl -X PUT \
"http://$DOCKER_HOST_IP:8083/connectors/person.dbzsrc.cdc/config" \
-H 'Content-Type: application/json' \
-H 'Accept: application/json' \
-d '{
"connector.class": "io.debezium.connector.postgresql.PostgresConnector",
"tasks.max": "1",
"database.server.name": "postgresql",
"database.port": "5432",
"database.user": "postgres",
"database.password": "<PASSWORD>!",
"database.dbname": "postgres",
"schema.include.list": "cdc_demo",
"table.include.list": "cdc_demo.person, cdc_demo.address",
"plugin.name": "pgoutput",
"tombstones.on.delete": "false",
"database.hostname": "postgresql",
"topic.creation.default.replication.factor": 3,
"topic.creation.default.partitions": 8,
"topic.creation.default.cleanup.policy": "compact"
}'
```
#### Check the data in the two Kafka topics
Now let's start two consumers, one on each topic, in separate terminal windows. This time the data is in Avro, as we did not overwrite the serializers. By default the topics are formatted using this naming convention: `<db-host>.<schema>.<table>`
```bash
kcat -b kafka-1:19092 -t postgresql.cdc_demo.person -f '[%p] %k: %s\n' -q -s avro -r http://schema-registry-1:8081
```
and you should get the change record for `person` table
```json
[0] {"id": 1}: {"before": null, "after": {"Value": {"id": 1, "title": {"string": "Mr"}, "first_name": {"string": "Peter"}, "last_name": {"string": "Muster"}, "email": {"string": "<EMAIL>"}, "modifieddate": 1654534797865686}}, "source": {"version": "1.8.1.Final", "connector": "postgresql", "name": "postgresql", "ts_ms": 1654534797866, "snapshot": {"string": "false"}, "db": "postgres", "sequence": {"string": "[\"23426176\",\"23426176\"]"}, "schema": "person", "table": "person", "txId": {"long": 556}, "lsn": {"long": 23426176}, "xmin": null}, "op": "c", "ts_ms": {"long": 1654534798250}, "transaction": null}
```
We can see that the key is also Avro-serialized (`{"id": 1}`).
Now do the same for the `postgresql.cdc_demo.address` topic
```bash
kcat -b kafka-1:19092 -t postgresql.cdc_demo.address -f '[%p] %k: %s\n' -q -s avro -r http://schema-registry-1:8081
```
and you should get the change record for the `address` table.
Let's use `jq` to format the value only (by removing the `-f` parameter).
```
kcat -b kafka-1:19092 -t postgresql.cdc_demo.person -f '%s\n' -q -s avro -r http://schema-registry-1:8081 -u | jq
```
we can see that the change record is wrapped inside the `after` field. The `op` field show the operation, which shows `c` for create/insert.
```json
{
"before": null,
"after": {
"Value": {
"id": 1,
"title": {
"string": "Mr"
},
"first_name": {
"string": "Peter"
},
"last_name": {
"string": "Muster"
},
"email": {
"string": "<EMAIL>"
},
"modifieddate": 1654534797865686
}
},
"source": {
"version": "1.8.1.Final",
"connector": "postgresql",
"name": "postgresql",
"ts_ms": 1654534797866,
"snapshot": {
"string": "false"
},
"db": "postgres",
"sequence": {
"string": "[\"23426176\",\"23426176\"]"
},
"schema": "cdc_demo",
"table": "person",
"txId": {
"long": 556
},
"lsn": {
"long": 23426176
},
"xmin": null
},
"op": "c",
"ts_ms": {
"long": 1654534798250
},
"transaction": null
}
```
Now let's do an update of the `person` table (keep the `kcat` running).
```sql
UPDATE cdc_demo.person SET first_name = UPPER(first_name);
```
and you should get the new change record
```json

#### Also produce the before image of an Update
You can see that there is `before` field but it is `null`. By default the Postgresql [`REPLICA IDENTITY`](https://www.postgresql.org/docs/9.6/sql-altertable.html#SQL-CREATETABLE-REPLICA-IDENTITY) will not produce the before image.
Let's change it on the `person` table to see the difference
```sql
alter table cdc_demo.person REPLICA IDENTITY FULL;
```
and then once more update the `person` table (keep the `kcat` running).
```sql
UPDATE cdc_demo.person SET first_name = LOWER(first_name);
```
we can now see both the data `before` and `after` the UPDATE:
```json
{
"before": {
"Value": {
"id": 1,
"title": {
"string": "Mr"
},
"first_name": {
"string": "PETER"
},

},
"transaction": null
}
```
#### Check the latency from the UPDATE until you consume the message from the topic
Let's do an update on the `address` table and make sure that you see the `kcat` in another terminal window
```sql
UPDATE cdc_demo.address SET street = UPPER(street);
```
```bash
kcat -b kafka-1:19092 -t postgresql.cdc_demo.address -f '[%p] %k: %s\n' -q -s avro -r http://schema-registry-1:8081
```
You should see a very minimal latency between doing the update and the message in Kafka.
#### Change the name of the Kafka Topic
The topic name might not fit with your naming conventions. You can change the name using a [Single Message Transforms (SMT)](https://docs.confluent.io/platform/current/connect/transforms/overview.html) as we have already seen in the query-based CDC workshop above.
Let's remove the connector and delete the two topics
```bash
curl -X "DELETE" "http://$DOCKER_HOST_IP:8083/connectors/person.dbzsrc.cdc"
docker exec -ti kafka-1 kafka-topics --delete --bootstrap-server kafka-1:19092 --topic postgresql.person.person
docker exec -ti kafka-1 kafka-topics --delete --bootstrap-server kafka-1:19092 --topic postgresql.person.address
```
Now recreate the connector, this time adding the necessary `RegexRouter` SMT:
```bash
curl -X PUT \
"http://$DOCKER_HOST_IP:8083/connectors/person.dbzsrc.cdc/config" \
-H 'Content-Type: application/json' \
-H 'Accept: application/json' \
-d '{
"connector.class": "io.debezium.connector.postgresql.PostgresConnector",
"tasks.max": "1",
"database.server.name": "postgresql",
"database.port": "5432",
"database.user": "postgres",
"database.password": "<PASSWORD>!",
"database.dbname": "postgres",
"schema.include.list": "cdc_demo",
"table.include.list": "cdc_demo.person, cdc_demo.address",
"plugin.name": "pgoutput",
"tombstones.on.delete": "false",
"database.hostname": "postgresql",
"transforms":"dropPrefix",
"transforms.dropPrefix.type": "org.apache.kafka.connect.transforms.RegexRouter",
"transforms.dropPrefix.regex": "postgresql.cdc_demo.(.*)",
"transforms.dropPrefix.replacement": "priv.$1.cdc.v2",
"topic.creation.default.replication.factor": 3,
"topic.creation.default.partitions": 8,
"topic.creation.default.cleanup.policy": "compact"
}'
```
Now let's do an update on `person` table once more
```sql
UPDATE cdc_demo.person SET first_name = UPPER(first_name);
```
to see the new topic `priv.person.cdc.v2` created
```bash
kcat -b kafka-1:19092 -t priv.person.cdc.v2 -f '[%p] %k: %s\n' -q -s avro -r http://schema-registry-1:8081
```
#### Remove the connector
We have successfully tested the log-based CDC connector. So let's remove the connector.
```bash
curl -X "DELETE" "http://$DOCKER_HOST_IP:8083/connectors/person.dbzsrc.cdc"
```
## Transactional Outbox Pattern using Debezium and Kafka Connect
In this section we will see how we can use [Debezium](https://debezium.io/) and it's Postgresql connector to perform log-based CDC on an special `outbox` table, implementing the [Transactional Outbox Pattern](https://microservices.io/patterns/data/transactional-outbox.html).
The [Debezium connector](https://www.confluent.io/hub/debezium/debezium-connector-postgresql), which supports the Outbox Pattern comes pre-installed with the Dataplatform stack.
#### Create the `outbox` table
In a new terminal window, connect to Postgresql
```bash
docker exec -ti postgresql psql -d postgres -U postgres
```
Now create a new table `outbox`
```sql
SET search_path TO cdc_demo;
DROP TABLE IF EXISTS "cdc_demo"."outbox";
CREATE TABLE "cdc_demo"."outbox" (
"id" uuid NOT NULL,
"aggregate_id" bigint,
"created_at" timestamp,
"event_type" character varying(255),
"payload_json" character varying(5000),
CONSTRAINT "outbox_pk" PRIMARY KEY ("id")
);
```
#### Create the Debezium connector
```bash
curl -X PUT \
"http://$DOCKER_HOST_IP:8083/connectors/person.dbzsrc.outbox/config" \
-H 'Content-Type: application/json' \
-H 'Accept: application/json' \
-d '{
"connector.class": "io.debezium.connector.postgresql.PostgresConnector",
"tasks.max": "1",
"database.server.name": "postgresql",
"database.port": "5432",
"database.user": "postgres",
"database.password": "<PASSWORD>!",
"database.dbname": "postgres",
"schema.include.list": "cdc_demo",
"table.include.list": "cdc_demo.outbox",
"plugin.name": "pgoutput",
"tombstones.on.delete": "false",
"database.hostname": "postgresql",
"transforms": "outbox",
"transforms.outbox.type": "io.debezium.transforms.outbox.EventRouter",
"transforms.outbox.table.field.event.id": "id",
"transforms.outbox.table.field.event.key": "aggregate_id",
"transforms.outbox.table.field.event.payload": "payload_json",
"transforms.outbox.table.field.event.timestamp": "created_at",
"transforms.outbox.route.by.field": "event_type",
"transforms.outbox.route.topic.replacement": "priv.${routedByValue}.event.v1",
"topic.creation.default.replication.factor": 3,
"topic.creation.default.partitions": 8
}'
```
#### Add data to `outbox` table
Let's first simulate a `CustomerCreated` event:
```sql
INSERT INTO cdc_demo.outbox (id, aggregate_id, created_at, event_type, payload_json)
VALUES (gen_random_uuid(), 13256, current_timestamp, 'CustomerCreated', '{"id":13256,"personType":"IN","nameStyle":"0","firstName":"Carson","middleName":null,"lastName":"Washington","emailPromotion":1,"addresses":[{"addressTypeId":2,"id":22326,"addressLine1":"3809 Lancelot Dr.","addressLine2":null,"city":"Glendale","stateProvinceId":9,"postalCode":"91203","country":{"isoCode2":"US","isoCode3":"USA","numericCode":840,"shortName":"United States of America"},"lastChangeTimestamp":"2022-05-09T20:45:11.798376"}],"phones":[{"phoneNumber":"518-555-0192","phoneNumberTypeId":1,"phoneNumberType":"Cell"}],"emailAddresses":[{"id":12451,"emailAddress":"<EMAIL>"}]}');
```
A new Kafka topic `priv.CustomerCreated.event.v1` will get created with the message.
```bash
kcat -b kafka-1:19092 -t priv.CustomerCreated.event.v1 -f '[%p] %k: %s\n' -q -s avro -r http://schema-registry-1:8081
```
```bash
[4] {"long": 13256}: {"string": "{\"id\":13256,\"personType\":\"IN\",\"nameStyle\":\"0\",\"firstName\":\"Carson\",\"middleName\":null,\"lastName\":\"Washington\",\"emailPromotion\":1,\"addresses\":[{\"addressTypeId\":2,\"id\":22326,\"addressLine1\":\"3809 Lancelot Dr.\",\"addressLine2\":null,\"city\":\"Glendale\",\"stateProvinceId\":9,\"postalCode\":\"91203\",\"country\":{\"isoCode2\":\"US\",\"isoCode3\":\"USA\",\"numericCode\":840,\"shortName\":\"United States of America\"},\"lastChangeTimestamp\":\"2022-05-09T20:45:11.798376\"}],\"phones\":[{\"phoneNumber\":\"518-555-0192\",\"phoneNumberTypeId\":1,\"phoneNumberType\":\"Cell\"}],\"emailAddresses\":[{\"id\":12451,\"emailAddress\":\"<EMAIL>\"}]}"}
```
Now let's also simulate another event, an `CustomerMoved` event
```sql
INSERT INTO cdc_demo.outbox (id, aggregate_id, created_at, event_type, payload_json)
VALUES (gen_random_uuid(), 13256, current_timestamp, 'CustomerMoved', '{"customerId": 13256, "address": {"addressTypeId":2,"id":22326,"addressLine1":"3809 Lancelot Dr.","addressLine2":null,"city":"Glendale","stateProvinceId":9,"postalCode":"91203","country":{"isoCode2":"US","isoCode3":"USA","numericCode":840,"shortName":"United States of America"},"lastChangeTimestamp":"2022-05-09T20:45:11.798376"}}');
```
this will end up in a new topic named `priv.CustomerMoved.event.v1`
```bash
kcat -b kafka-1:19092 -t priv.CustomerMoved.event.v1 -f '[%p] %k: %s\n' -q -s avro -r http://schema-registry-1:8081
```
```bash
[4] {"long": 13256}: {"string": "{\"customerId\": 13256, \"address\": {\"addressTypeId\":2,\"id\":22326,\"addressLine1\":\"3809 Lancelot Dr.\",\"addressLine2\":null,\"city\":\"Glendale\",\"stateProvinceId\":9,\"postalCode\":\"91203\",\"country\":{\"isoCode2\":\"US\",\"isoCode3\":\"USA\",\"numericCode\":840,\"shortName\":\"United States of America\"},\"lastChangeTimestamp\":\"2022-05-09T20:45:11.798376\"}}"}
```
#### Remove the connector
We have successfully tested the transactional outbox using Debezium connector. So let's remove the connector.
```bash
curl -X "DELETE" "http://$DOCKER_HOST_IP:8083/connectors/person.dbzsrc.outbox"

# Azure Event Hub as external Kafka
This recipe will show how to use Azure Event Hub as an external Kafka cluster.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```bash
export DATAPLATFORM_HOME=${PWD}
platys init --enable-services KAFKA_CONNECT,AKHQ -s trivadis/platys-modern-data-platform -w 1.16.0
```
Edit the `config.yml`
bash
```
external:
KAFKA_enable: true
KAFKA_bootstrap_servers: XXXXXX.servicebus.windows.net:9093
KAFKA_security_protocol: SASL_SSL
KAFKA_sasl_mechanism: PLAIN
KAFKA_sasl_username: $$ConnectionString
```
For the password to not end up in the `docker-compose.yml` file, we have to add it as an environment variable:
Create a `.env` file
```
nano .env
```
and add the following environment variable to specify the password
```bash
PLATYS_KAFKA_PASSWORD=Endpoint=sb://fzageventhub.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=<KEY>
```
Save the file and generate and start the data platform.
```bash
platys gen
docker-compose up -d
```
## Use the Platform
Navigate to AKHQ to manage the Event Hub: <http://dataplatform:28107>
To use the Kafka CLI's
```bash
docker exec -ti kafka-cli kafka-topics --bootstrap-server XXXXXX.servicebus.windows.net:9093 --command-config config.properties --list
```

<file_sep># Using Spark Structured Streaming for Stream Analytics
In this workshop we will learn how to process messages using Spark Structured Streaming.
With Spark Structured Streaming we assume the data to be available in JSON. Therefore we first transform it using ksqlDB using the ksqlDB stream created in workshop 13b.
```sql
CREATE STREAM truck_position_json_s
WITH (kafka_topic='truck_position_json',
value_format='JSON')
AS
SELECT * FROM truck_position_s
EMIT CHANGES;
```
## Creating Spark environment in Zeppelin
In a web browser navigate to Zeppelin on <http://dataplatform:28080>.
Let's create a local Spark environment by adding a new interpreter. On the right corner, click on **Admin** and select **Interpreter**
Click on **Create** to create a new Interpreter and set **Interpreter Name** to `spark-local` and select `spark` for the **Interpreter Group**.
Scroll down to **Dependencies** and add `org.apache.spark:spark-sql-kafka-0-10_2.12:3.1.3` into the **Artifact** field.
Click **Save** to create the interpreter.
## Creating a new notebook in Zeppelin
Create a new Notebook and select the `spark-local`
## Implement Spark Structured Streaming pipeline in Python
### Define Schema for truck_position events/messages
```python
%pyspark
from pyspark.sql.types import *
truckPositionSchema = StructType().add("TS", StringType()).add("TRUCKID",StringType()).add("DRIVERID", LongType()).add("ROUTEID", LongType()).add("EVENTTYPE", StringType()).add("LATITUDE", DoubleType()).add("LONGITUDE", DoubleType()).add("CORRELATIONID", StringType())
```
### Kafka Consumer
```python
rawDf = spark
.readStream
.format("kafka")
.option("kafka.bootstrap.servers", "kafka-1:19092,kafka-2:19093")
.option("subscribe", "truck_position_json")
.load()
```
### Show the schema of the raw Kafka message
```python
rawDf.printSchema
```
### Map to "truck_position" schema and extract event time (trunc to seconds)
```python
%pyspark
from pyspark.sql.functions import from_json
jsonDf = rawDf.selectExpr("CAST(value AS string)")
jsonDf = jsonDf.select(from_json(jsonDf.value, truckPositionSchema).alias("json")).selectExpr("json.*", "cast(cast (json.timestamp as double) / 1000 as timestamp) as eventTime")
```
### Show schema of data frame
```python
%pyspark
jsonDf.printSchema
```
### Run 1st query into in memory "table"
```python
%pyspark
query1 = jsonDf.writeStream.format("memory").queryName("truck_position").start()
```
### Using Spark SQL to read from the in-memory "table"
```python
%pyspark
spark.sql ("select * from truck_position").show()
```
or in Zeppelin using the %sql directive
```sql
%sql
select * from truck_position
```
### Stop the query
```python
%pyspark
query1.stop()
```
### Filter out normal events
```python
%pyspark
jsonDf.printSchema
jsonFilteredDf = jsonDf.where("json.EVENTTYPE !='Normal'")
```
### Run 2nd query on filtered data into in memory "table"
```python
%pyspark
query2 = jsonFilteredDf.writeStream.format("memory").queryName("filtered_truck_position").start()
```
### Use Spark SQL
```python
%pyspark
spark.sql ("select * from filtered_truck_position2").show()
```
### Stop 2nd query
```python
%pyspark
query2.stop
```
### Run 3rd query - Write non-normal events to Kafka topic
Create a new topic
```
docker exec -ti kafka-1 kafka-topics --create --zookeeper zookeeper-1:2181 --topic dangerous_driving_spark --partitions 8 --replication-factor 3
```
```python
%pyspark
query3 = jsonFilteredDf.selectExpr("to_json(struct(*)) AS value").writeStream.format("kafka").option("kafka.bootstrap.servers", "kafka-1:19092").option("topic","dangerous_driving_spark").option("checkpointLocation", "/tmp").start()
```
### Stop 3rd query
```python
query3.stop
```

## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started.md) with the following services enabled
```
platys init --enable-services SPARK,POSTGRESQL,ZEPPELIN,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.11.0
```
Before we can generate the platform, we need to extend the `config.yml` with the following SPARK property:
```
SPARK_jars_packages: 'org.postgresql:postgresql:9.4.1212'
```
Now set an environment variable to the home folder of the dataplatform and generate and then start the data platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Create Table in Postgresql
```bash
docker exec -ti postgresql psql -d demodb -U demo
```
```sql
CREATE SCHEMA flight_data;
DROP TABLE flight_data.airport_t;
CREATE TABLE flight_data.airport_t
(
iata character varying(50) NOT NULL,
airport character varying(50),
city character varying(50),
state character varying(50),
country character varying(50),
lat float,
long float,
CONSTRAINT airport_pk PRIMARY KEY (iata)
);
```
```sql
COPY flight_data.airport_t(iata,airport,city,state,country,lat,long)
FROM '/data-transfer/flight-data/airports.csv' DELIMITER ',' CSV HEADER;
```
## Work with data from PostgreSQL
Navigate to Zeppelin <http://dataplatform:28080> and login as user `admin` with password `<PASSWORD>!`.
Create a new notebook and in a cell enter the following Spark code using the Python API. Replace again the `gschmutz` prefix in the bucket name:
```scala
val opts = Map(
"url" -> "jdbc:postgresql://postgresql/demodb?user=demo&password=<PASSWORD>!",
"driver" -> "org.postgresql.Driver",
"dbtable" -> "flight_data.airport_t")
val df = spark
.read
.format("jdbc")
.options(opts)
.load
```
```
df.show
```

# Using Confluent Enterprise Tiered Storage
This recipe will show how to support activation of StreamSets Data Collector in persistent and replayable way.
The problem with the activation of StreamSets is, that an activation code is given for a given `SDC ID` (a.k.a product id). If you restart the StreamSets Data Collector container, everything is fine, but if you stop, remove and recrate the container, a new `SDC ID` is generated and you have to re-activate StreamSets.
This recipe shows, how the `SDC ID` can be fixed to a value, so that recreating a container won't change it.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services KAFKA,PLATYS -s trivadis/platys-modern-data-platform -w 1.13.0
```
Edit the `config.yml` and add the following configuration settings.
```
KAFKA_edition: 'enterprise'
KAFKA_confluent_tier_enable: true
KAFKA_confluent_tier_feature: true
KAFKA_confluent_tier_s3_aws_endpoint_override: http://minio-1:9000
KAFKA_confluent_tier_s3_force_path_style_access: true
KAFKA_confluent_tier_local_hotset_ms: 0
KAFKA_confluent_tier_local_hotset_bytes: -1
KAFKA_confluent_tier_archiver_num_threads: 8
KAFKA_confluent_tier_fetcher_num_threads: 16
KAFKA_confluent_tier_topic_delete_check_interval_ms: 60000
KAFKA_log_segment_bytes: 1048576
```
Now generate data platform
```
platys gen
```
and then start the platform:
```
docker-compose up -d
```

Navigate to <http://dataplatform:28131><file_sep># Using Kafka from Java with Avro & Schema Registry
In this workshop we will learn how to produce and consume messages using the [Kafka Java API](https://kafka.apache.org/documentation/#api) using Avro for serialising and deserialising messages.
## Create the project in your Java IDE
Create a new Maven Project (using the functionality of your IDE) and in the last step use `com.trivadis.kafkaws` for the **Group Id** and `java-avro-kafka` for the **Artifact Id**.
Navigate to the **pom.xml** and double-click on it. The POM Editor will be displayed.
You can either use the GUI to edit your `pom.xml` or navigate to the last tab **pom.xml** to switch to the "code view". Let's do that.
You will see the still rather empty definition.
```xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>com.trivadis.kafkaws</groupId>
<artifactId>java-avro-kafka</artifactId>
<version>0.0.1-SNAPSHOT</version>
</project>
```
Let's add some initial dependencies for our project. We will add some more dependencies to the POM throughout this workshop.
Copy the following block right after the `<version>` tag, before the closing `</project>` tag.
```xml

## Create log4j settings
Let's also create the necessary log4j configuration.
In the code we are using the [Log4J Logging Framework](https://logging.apache.org/log4j/2.x/), which we have to configure using a property file.
Create a new file `log4j.properties` in the folder **src/main/resources** and add the following configuration properties.
```

```
## Creating the necessary Kafka Topic
We will use the topic `test-java-avro-topic` in the Producer and Consumer code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
In a terminal window, connect to the `kafka-1` container
```
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```
kafka-topics --create \
--replication-factor 3 \
--partitions 12 \
--topic test-java-avro-topic \
--bootstrap-server kafka-1:19092,kafka-2:19093
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing the **Kafka Producer** which uses Avro for the serialisation.
## Create an Avro Schema representing the Notification Message
First create a new Folder `avro` under the existing folder **src/main/**.
Create a new File `Notification-v1.avsc` in the folder **src/main/avro** just created above.
Add the following Avro schema to the empty file.
```json
{
"type" : "record",
"namespace" : "com.trivadis.kafkaws.avro.v1",
"name" : "Notification",
"description" : "A simple Notification Event message",
"fields" : [
{ "type" : ["long", "null"],
"name" : "id"
},
{ "type" : ["string", "null"],
"name" : "message"
}
]
}
```
In the `pom.xml`, add the `avro-maven-plugin` plugin to the `<build><plugins>` section, just below the `exec-maven-plugin`.
```xml
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<version>${avro.version}</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>schema</goal>
<goal>protocol</goal>
<goal>idl-protocol</goal>
</goals>
<configuration>
<fieldVisibility>private</fieldVisibility>
<sourceDirectory>${project.basedir}/src/main/avro</sourceDirectory>
</configuration>
</execution>
</executions>
</plugin>
```
This plugin will make sure, that classes are generated based on the Avro schema, whenever a `mvn compile` is executed. Let's exactly do that on the still rather empty project.
```
mvn compile
```
After running this command, refresh the project and you should see a new folder named `target/generated-sources/avro`. Expand into this folder and you should see one generated Java class named `Notification`.
Double click on the `Notification` class to inspect the code.
```java
package com.trivadis.kafkaws.avro.v1;
import org.apache.avro.specific.SpecificData;
@SuppressWarnings("all")
@org.apache.avro.specific.AvroGenerated
public class Notification extends org.apache.avro.specific.SpecificRecordBase implements org.apache.avro.specific.SpecificRecord {
private static final long serialVersionUID = 799361421243801515L;
public static final org.apache.avro.Schema SCHEMA$ = new org.apache.avro.Schema.Parser().parse("{\"type\":\"record\",\"name\":\"Notification\",\"namespace\":\"com.trivadis.kafkaws.avro.v1\",\"fields\":[{\"name\":\"id\",\"type\":[\"long\",\"null\"]},{\"name\":\"message\",\"type\":[\"string\",\"null\"]}],\"description\":\"A simple Notification Event message\"}");
public static org.apache.avro.Schema getClassSchema() { return SCHEMA$; }
private java.lang.Long id;
private java.lang.CharSequence message;
/**
* Default constructor. Note that this does not initialize fields
* to their default values from the schema. If that is desired then
* one should use <code>newBuilder()</code>.
*/
public Notification() {}
/**
* All-args constructor.
* @param id The new value for id
* @param message The new value for message
*/
public Notification(java.lang.Long id, java.lang.CharSequence message) {
this.id = id;
this.message = message;
}
...
```
You can see that the code is based on the information in the Avro schema. We will use this class when we produce as well as consume Avro messages to/from Kafka.
## Create a Kafka Producer using Avro for serialisation
First create a new Java Package `com.trivadis.kafkaws.producer` in the folder **src/main/java**.
Create a new Java Class `KafkaProducerAvro` in the package `com.trivadis.kafakws.producer` just created.
Add the following code to the empty class to create a Kafka Producer. It is similar to the code we have seen in the previous workshop. We have changed both serialiser to use the Confluent `KafkaAvroSerializer` class and added the URL to the Confluent Schema Registry API.
```java
package com.trivadis.kafkaws.producer;
import com.trivadis.kafkaws.avro.v1.Notification;
import io.confluent.kafka.serializers.KafkaAvroSerializer;
import io.confluent.kafka.serializers.KafkaAvroSerializerConfig;
import org.apache.kafka.clients.producer.*;
import java.util.Properties;
public class KafkaProducerAvro {
private final static String TOPIC = "test-java-avro-topic";
private final static String BOOTSTRAP_SERVERS =
"dataplatform:9092, dataplatform:9093, dataplatform:9094";
private final static String SCHEMA_REGISTRY_URL = "http://dataplatform:8081";
private static Producer<Long, Notification> createProducer() {
Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ProducerConfig.CLIENT_ID_CONFIG, "KafkaExampleProducer");
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, KafkaAvroSerializer.class.getName());
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, KafkaAvroSerializer.class.getName());
props.put(KafkaAvroSerializerConfig.SCHEMA_REGISTRY_URL_CONFIG, SCHEMA_REGISTRY_URL); // use constant for "schema.registry.url"
return new KafkaProducer<>(props);
}
}
```
We will be using the synchronous way for producing messages to the Kafka topic we created above, but the other methods would work as well with Avro.
```java
static void runProducer(final int sendMessageCount, final int waitMsInBetween, final long id) throws Exception {
final Producer<Long, Notification> producer = createProducer();
long time = System.currentTimeMillis();
Long key = (id > 0) ? id : null;
try {
for (long index = 0; index < sendMessageCount; index++) {
Notification notification = new Notification(id, "Hello Kafka " + index);
final ProducerRecord<Long, Notification> record =
new ProducerRecord<>(TOPIC, key, notification);
RecordMetadata metadata = producer.send(record).get();
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) " +
"meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
time = System.currentTimeMillis();
Thread.sleep(waitMsInBetween);
}
} finally {
producer.flush();
producer.close();
}
}
```
Next you define the main method.
```
public static void main(String... args) throws Exception {
if (args.length == 0) {
runProducer(100,10,0);
} else {
runProducer(Integer.parseInt(args[0]),Integer.parseInt(args[1]),Long.parseLong(args[2]));
}
}
```
The `main()` method accepts 3 parameters, the number of messages to produce, the time in ms to wait in-between sending each message and the ID of the producer.
Use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-java-avro-topic `.
```
kcat -b kafka-1:19092 -t test-java-avro-topic
```
Now run it using the `mvn exec:java` command. It will generate 1000 messages, waiting 10ms in-between sending each message and use 0 for the ID.
```
mvn exec:java@producer -Dexec.args="1000 10 0"
```
**Note:** if your maven version does not support profiles, then you have to specify the main class as well: `mvn exec:java -Dexec.mainClass="com.trivadis.kafkaws.producer.KafkaProducerAvro" -Dexec.args="1000 100 0"`
You can see that `kcat` shows some special, non-printable characters. This is due to the Avro format. If you want to display the Avro, you can use the `kafka-avro-console-consumer` CLI, which is part of the Schema Registry.
So let's connect to the schema registry container:
```
docker exec -ti schema-registry-1 bash
```
And then invoke the `kafka-avro-console-consumer` similar to the "normal" consumer seen so far.
```
kafka-avro-console-consumer --bootstrap-server kafka-1:19092 --topic test-java-avro-topic
```
You should see an output similar to the one below.
```
...

{"id":{"long":0},"message":{"string":"Hello Kafka 8"}}
...
```
if you want to consume with `kcat` you need to specify the serialization format `-s` and the address of the schema registry `-r`:
```
kcat -b kafka-1 -t test-java-avro-topic -s value=avro -r http://schema-registry-1:8081
```
**Note**: For Avro support your kafkacat version needs to be `1.6' or later.
## View the Schema in the Registry
The Avro Serialiser and Deserialiser automatically register the Avro schema, if it is not already in the registry.
The Streamingplatform also contains a tool made by a company called Landoop which allows us to see what's in the registry.
In a browser, navigate to <http://dataplatform:28039> and you should see the home page of the Schema Registry UI.
If you click on the schema to the left, you can view the details of the schema. You can see that version v1 has been assigned automatically.
## Create a Kafka Consumer using Avro for serialization
First create a new Java Package `com.trivadis.kafkaws.consumer` in the folder **src/main/java**.
Create a new Java Class `KafkaConsumerAvro` in the package `com.trivadis.kafakws.consumer` just created.
Add the following code to the empty class.
```java
package com.trivadis.kafkaws.consumer;
import java.util.Collections;
import java.util.Properties;
import org.apache.kafka.clients.consumer.Consumer;
import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.KafkaConsumer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.common.serialization.LongDeserializer;
import org.apache.kafka.common.serialization.StringDeserializer;
import com.trivadis.kafkaws.avro.v1.Notification;
import io.confluent.kafka.serializers.KafkaAvroDeserializer;
import io.confluent.kafka.serializers.KafkaAvroSerializer;
import io.confluent.kafka.serializers.KafkaAvroSerializerConfig;
public class KafkaConsumerAvro {
private final static String TOPIC = "test-java-avro-topic";
private final static String BOOTSTRAP_SERVERS =
"dataplatform:9092, dataplatform:9093, dataplatform:9094";
private final static String SCHEMA_REGISTRY_URL = "http://dataplatform:8081";
private static Consumer<Long, Notification> createConsumer() {
final Properties props = new Properties();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ConsumerConfig.GROUP_ID_CONFIG, "KafkaConsumerAvro");
props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, false);
props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, 10000);
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, KafkaAvroDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, KafkaAvroDeserializer.class.getName());
props.put(KafkaAvroSerializerConfig.SCHEMA_REGISTRY_URL_CONFIG, SCHEMA_REGISTRY_URL); // use constant for "schema.registry.url"
// Create the consumer using props.
final Consumer<Long, Notification> consumer =
new KafkaConsumer<>(props);
// Subscribe to the topic.
consumer.subscribe(Collections.singletonList(TOPIC));
return consumer;
}
static void runConsumer(int waitMsInBetween) throws InterruptedException {
final Consumer<Long, Notification> consumer = createConsumer();
final int giveUp = 100;
int noRecordsCount = 0;
while (true) {
final ConsumerRecords<Long, Notification> consumerRecords = consumer.poll(1000);
if (consumerRecords.count()==0) {
noRecordsCount++;
if (noRecordsCount > giveUp)
break;
}
consumerRecords.forEach(record -> {
System.out.printf("%d - Consumer Record:(Key: %d, Value: %s, Partition: %d, Offset: %d)\n",
consumerRecords.count(), record.key(), record.value(),
record.partition(), record.offset());
try {
Thread.sleep(waitMsInBetween);
} catch (InterruptedException e) {
}
});
consumer.commitSync();
}
consumer.close();
System.out.println("DONE");
}
public static void main(String... args) throws Exception {
if (args.length == 0) {
runConsumer(10);
} else {
runConsumer(Integer.parseInt(args[0]));
}
}
}
```
## Register in Schema Registry using Maven
In the test above, the Avro schema has been registered in the schema registry when starting the Producer for the first time. To register an Avro schema through Maven automatically, you can use the `kafka-schema-registry-maven-plugin` Maven plugin.
Add the following definition to the `pom.xml`.
```xml
<plugin>
<groupId>io.confluent</groupId>
<artifactId>kafka-schema-registry-maven-plugin</artifactId>
<version>7.0.0</version>
<configuration>
<schemaRegistryUrls>
<param>http://dataplatform:8081</param>
</schemaRegistryUrls>
<subjects>
<test-java-avro-topic-value>src/main/avro/Notification-v1.avsc</test-java-avro-topic-value>
</subjects>
</configuration>
<goals>
<goal>register</goal>
<goal>test-compatibility</goal>
</goals>
</plugin>
```
Now you can use the following command to register the schemas with the Schema Registry:
```
mvn schema-registry:register
```

In this workshop we will learn how to use the **Spring Cloud Stream** abstraction from within a Spring Boot application. We will implement both a consumer and a producer implementing the same behaviour as in [Workshop 4: Working with Kafka from Java](../04-producing-consuming-kafka-with-java).
We will create two Spring Boot projects, one for the **Producer** and one for the **Consumer**, simulating two independent microservices interacting with eachother via events.
## Create the Spring Boot Producer
First we create an test the Producer microservice.
### Creating the Spring Boot Project
First, let’s navigate to [Spring Initializr](https://start.spring.io/) to generate our project. Our project will need the Spring Cloud Stream support.
Select Generate a **Maven Project** with **Java** and Spring Boot **2.6.5**. Enter `com.trivadis.kafkaws` for the **Group**, `spring-boot-cloud-stream-kafka-producer` for the **Artifact** field and `Kafka Producer with Spring Cloud Stream (Kafka)` for the **Description** field.
Click on **Add Dependencies** and search for the **Cloud Stream** depencency.
Select the dependency and hit the **Enter** key. You should now see the dependency on the right side of the screen.
Click on **Generate Project** and unzip the ZIP file to a convenient location for development.
Once you have unzipped the project, you’ll have a very simple structure.
Import the project as a Maven Project into your favourite IDE for further development.
### Extend the Maven POM with some configurations
In oder to use the Avro serializer and the class generated above, we have to add the following dependencies to the `pom.xml`.
```xml
<dependencies>
...
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream-binder-kafka</artifactId>
</dependency>
```
### Implement a Kafka Producer in Spring
Now create a simple Java class `KafkaEventProducer` within the `com.trivadis.kafkaws.springbootkafkaproducer ` package, which we will use to produce messages to Kafka.
```java
package com.trivadis.kafkaws.springbootkafkaproducer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.stream.messaging.Processor;
import org.springframework.kafka.support.KafkaHeaders;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Service;
@Service
public class KafkaEventProducer {
private static final Logger LOGGER = LoggerFactory.getLogger(KafkaEventProducer.class);
@Autowired
private Processor processor;
@Value("${topic.name}")
String kafkaTopic;
public void produce(Integer id, Long key, String value) {
long time = System.currentTimeMillis();
Message<String> message = MessageBuilder.withPayload(value)
.setHeader(KafkaHeaders.MESSAGE_KEY, key)
.build();
processor.output()
.send(message);
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) time=%d\n",key, value,elapsedTime);
}
}
```
It uses the `Component` annotation to have it registered as bean in the Spring context. The topic to produce to is specified as a property, which we will specify later in the `applicaiton.yml` file.
We produce the messages synchronously.
### Create the necessary Topics through code
Spring Kafka can automatically add topics to the broker, if they do not yet exists. By that you can replace the `kafka-topics` CLI commands seen so far to create the topics, if you like.
Spring Kafka provides a `TopicBuilder` which makes the creation of the topics very convenient.
```java
package com.trivadis.kafkaws.springbootkafkaproducer;
import org.apache.kafka.clients.admin.NewTopic;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.kafka.config.TopicBuilder;
import org.springframework.stereotype.Component;
@Component
public class TopicCreator {
@Value(value = "${topic.name}")
private String testTopic;
@Value(value = "${topic.partitions}")
private Integer testTopicPartitions;
@Value(value = "${topic.replication-factor}")
private short testTopicReplicationFactor;
@Bean
public NewTopic testTopic() {
return TopicBuilder.name(testTopic)
.partitions(testTopicPartitions)
.replicas(testTopicReplicationFactor)
.build();
}
}
```
We again refer to properties, which will be defined later in the `application.yml` config file.
### Add Producer logic to the SpringBootKafkaProducerApplication class
We change the generated Spring Boot application to be a console appliation by implementing the `CommandLineRunner` interface. The `run` method holds the same code as the `main()` method in [Workshop 4: Working with Kafka from Java](../04-producing-consuming-kafka-with-java). The `runProducer` method is also similar, we just use the `kafkaEventProducer` instance injected by Spring to produce the messages to Kafka.
```java
package com.trivadis.kafkaws.springbootkafkaproducer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.messaging.Processor;
import java.time.LocalDateTime;
@SpringBootApplication
@EnableBinding(Processor.class)
public class SpringBootKafkaProducerApplication implements CommandLineRunner {
private static Logger LOG = LoggerFactory.getLogger(SpringBootKafkaProducerApplication.class);
@Autowired
private KafkaEventProducer kafkaEventProducer;
public static void main(String[] args) {
SpringApplication.run(SpringBootKafkaProducerApplication.class, args);
}
@Override
public void run(String... args) throws Exception {
LOG.info("EXECUTING : command line runner");
if (args.length == 0) {
runProducer(100, 10, 0);
} else {
runProducer(Integer.parseInt(args[0]), Integer.parseInt(args[1]), Long.parseLong(args[2]));
}
}
private void runProducer(int sendMessageCount, int waitMsInBetween, long id) throws Exception {
Long key = (id > 0) ? id : null;
for (int index = 0; index < sendMessageCount; index++) {
String value = "[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now();
kafkaEventProducer.produce(index, key, value);
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
```
### Configure Kafka through application.yml configuration file
First let's rename the existing `application.properties` file to `application.yml` to use the `yml` format.
Add the following settings to configure the Kafka cluster and the name of the topic:
```yml
topic:
name: test-spring-cloud-stream-topic
replication-factor: 3
partitions: 12
spring:
cloud:
stream:
default:
producer:
useNativeEncoding: true
kafka:
binder:
producer-properties:
key.serializer: org.apache.kafka.common.serialization.LongSerializer
value.serializer: org.apache.kafka.common.serialization.StringSerializer
bindings:
output:
destination: ${topic.name}
kafka:
bootstrap-servers: ${DATAPLATFORM_IP}:9092
```
For the IP address of the Kafka cluster we refer to an environment variable, which we have to declare before running the application.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
### Build the application
First lets build the application:
```bash
mvn package -Dmaven.test.skip=true
```
### Run the application
Now let's run the application
```bash
mvn spring-boot:run
```
Make sure that you see the messages through the console consumer.
To run the producer with custom parameters (for example to specify the key to use), use the `-Dspring-boot.run.arguments`:
```bash
mvn spring-boot:run -Dspring-boot.run.arguments="100 10 10"
```
### Use Console to test the application
In a terminal window start consuming from the output topic:
```bash
kafkacat -b $DATAPLATFORM_IP -t test-spring-topic
```
## Create the Spring Boot Consumer
Now let's create an test the Consumer microservice.
### Creating the Spring Boot Project
Use again the [Spring Initializr](https://start.spring.io/) to generate the project.
Select Generate a **Maven Project** with **Java** and Spring Boot **2.6.5**. Enter `com.trivadis.kafkaws` for the **Group**, `spring-boot-cloud-stram-kafka-consumer` for the **Artifact** field and `Kafka Consumer project for Spring Boot` for the **Description** field.
Click on **Add Dependencies** and search for the **Spring for Apache Kafka** depencency.
Select the dependency and hit the **Enter** key. You should now see the dependency on the right side of the screen.
Click on **Generate Project** and unzip the ZIP file to a convenient location for development.
Once you have unzipped the project, you’ll have a very simple structure.
Import the project as a Maven Project into your favourite IDE for further development.
### Implement a Kafka Consumer in Spring
Start by creating a simple Java class `KafkaEventConsumer` within the `com.trivadis.kafkaws.springbootkafkaconsumer` package, which we will use to consume messages from Kafka.
```java
package com.trivadis.kafkaws.springcloudstreamkafkaconsumer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.cloud.stream.annotation.StreamListener;
import org.springframework.cloud.stream.messaging.Processor;
import org.springframework.kafka.support.KafkaHeaders;
import org.springframework.messaging.Message;
import org.springframework.stereotype.Component;
@Component
public class KafkaEventConsumer {
private static final Logger LOGGER = LoggerFactory.getLogger(KafkaEventConsumer.class);
@StreamListener(Processor.INPUT)
public void receive(Message<String> msg) {
String value = msg.getPayload();
Long key = (Long)msg.getHeaders().get(KafkaHeaders.RECEIVED_MESSAGE_KEY);
LOGGER.info("received key = '{}' with payload='{}'", key, value);
}
}
```
This class uses the `Component` annotation to have it registered as bean in the Spring context and the `StreamListener` annotation to specify a listener method to be called for each record consumed from the Kafka input topic. The name of the topic is specified as a property to be read again from the `application.yml` configuration file.
In the code we only log the key and value received to the console. In real life, we would probably inject another bean into the `KafkaEventConsumer` to perform the message processing.
### Add @EnableBinding to Application class
Add the following annotation to the `SpringCloudStreamKafkaConsumerAvroApplication` class
```yml
@EnableBinding(Processor.class)
public class SpringCloudStreamKafkaConsumerAvroApplication {
...
```
### Configure Kafka through application.yml configuration file
First let's rename the existing `application.properties` file to `application.yml` to use the `yml` format.
Add the following settings to configure the Kafka cluster and the name of the two topics:
```yml
spring:
cloud:
stream:
default:
consumer:
useNativeEncoding: true
bindings:
input:
destination: test-spring-cloud-stream-topic
group: group-1
concurrency: 3
kafka:
binder:
consumer-properties:
key.deserializer: org.apache.kafka.common.serialization.LongDeserializer
value.deserializer: org.apache.kafka.common.serialization.StringDeserializer
kafka:
bootstrap-servers: ${DATAPLATFORM_IP}:9092
```
For the IP address of the Kafka cluster we refer to an environment variable, which we have to declare before running the application.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
### Build the application
First lets build the application:
```bash
mvn package -Dmaven.test.skip=true
```
### Run the application
Now let's run the application
```bash
mvn spring-boot:run
```

<file_sep># Working with Kafka from Java
In this workshop we will learn how to produce and consume messages using the [Kafka Java API](https://kafka.apache.org/documentation/#api).
We will fist use just the `StringSerializer` to serialize a `java.lang.String` object for the value of the message. In a second step we will change it to serialize a custom Java bean as a JSON document.
## Create the project in your Java IDE
Create a new Maven Project (using the functionality of your favourite IDE) and use `com.trivadis.kafkaws` for the **Group Id** and `java-kafka` for the **Artifact Id**.
Navigate to the **pom.xml** and double-click on it. The POM Editor will be displayed.
You can either use the GUI to edit your pom.xml or click on the last tab **pom.xml** to switch to the "code view". Let's do that.
You will see the still rather empty definition.
```xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.trivadis.kafkaws</groupId>
<artifactId>java-kafka</artifactId>
<version>0.0.1-SNAPSHOT</version>
</project>
```
Let's add some initial dependencies for our project. We will add some more dependencies to the POM throughout this workshop.
Copy the following block right after the <version> tag, before the closing </project> tag.
```xml
<properties>
<kafka.version>2.7.0</kafka.version>

## Create log4j settings
Let's also create the necessary log4j configuration.
In the code we are using the [Log4J Logging Framework](https://logging.apache.org/log4j/2.x/), which we have to configure using a property file.
Create a new file `log4j.properties` in the folder **src/main/resources** and add the following configuration properties.
```properties

```
## Creating the necessary Kafka Topic
We will use the topic `test-java-topic` in the Producer and Consumer code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
Connect to the `kafka-1` container
```bash
docker exec -ti kafka-1 bash
```
and execute the necessary `kafka-topics` command.
```bash
kafka-topics --create \
--replication-factor 3 \
--partitions 12 \
--topic test-java-topic \
--bootstrap-server kafka-1:19092
```
Cross check that the topic has been created.
```bash
kafka-topics --list --bootstrap-server kafka-1:19092
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing a **Kafka Producer**.
## Create a Kafka Producer
Let's first create a producer in synchronous mode.
### Using the Synchronous mode
First create a new Java Package `com.trivadis.kafkaws.producer` in the folder **src/main/java**.
Create a new Java Class `KafkaProducerSync` in the package `com.trivadis.kafkaws.producer` just created.
Add the following code to the empty class to create a Kafka Producer.
```java
package com.trivadis.kafkaws.producer;
import java.time.LocalDateTime;
import java.util.Properties;
import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.Producer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.clients.producer.ProducerRecord;
import org.apache.kafka.clients.producer.RecordMetadata;
import org.apache.kafka.common.serialization.LongSerializer;
import org.apache.kafka.common.serialization.StringSerializer;
public class KafkaProducerSync {
private final static String TOPIC = "test-java-topic";
private final static String BOOTSTRAP_SERVERS
= "dataplatform:9092,dataplatform:9093";
private static Producer<Long, String> createProducer() {
Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ProducerConfig.CLIENT_ID_CONFIG, "KafkaExampleProducer");
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG,
LongSerializer.class.getName());
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,
StringSerializer.class.getName());
return new KafkaProducer<>(props);
}
}
```
Kafka provides a synchronous send method to send a record to a topic. Let’s use this method to send some message ids and messages to the Kafka topic we created earlier.
```java
private static void runProducer(int sendMessageCount, int waitMsInBetween, long id) throws Exception {
try (Producer<Long, String> producer = createProducer()) {
for (int index = 0; index < sendMessageCount; index++) {
long time = System.currentTimeMillis();
ProducerRecord<Long, String> record
= new ProducerRecord<>(TOPIC,
"[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now());
RecordMetadata metadata = producer.send(record).get();
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) "
+ "meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
```
Next you define the main method.
```java
public static void main(String... args) throws Exception {
if (args.length == 0) {
runProducer(100, 10, 0);
} else {
runProducer(Integer.parseInt(args[0]), Integer.parseInt(args[1]), Long.parseLong(args[2]));
}
}
```
The `main()` method accepts 3 parameters, the number of messages to produce, the time in ms to wait in-between sending each message and the ID of the producer.
Now run it using the `mvn exec:java` command. It will generate 1000 messages, waiting 100ms in-between sending each message and use 0 for the ID, which will set the key to `null`.
```bash
mvn clean package -Dmaven.test.skip=true
mvn exec:java@producer -Dexec.args="1000 100 0"
```
**Note**: if your maven version does not support profiles, then you have to specify the main class as well: `mvn exec:java -Dexec.mainClass="com.trivadis.kafkaws.producer.KafkaProducerSync" -Dexec.args="1000 100 0"`
if you don't have `kafkacat` or `kcat` available, you can use it as a docker container. To simplify using `kcat`, you can use the following alias:
```bash
alias kcat='docker run --tty --network host edenhill/kcat:1.7.0 kcat'
```
Use `kafkacat` or `kafka-console-consumer` to consume the messages from the topic `test-java-topic`.
```bash
kcat -b kafka-1:19092 -t test-java-topic -f 'Part-%p => %k:%s\n'
```
```bash
% Auto-selecting Consumer mode (use -P or -C to override)

Part-4 => :[0] Hello Kafka 25

Part-3 => :[0] Hello Kafka 28
Part-6 => :[0] Hello Kafka 29
Part-0 => :[0] Hello Kafka 30
Part-3 => :[0] Hello Kafka 36
Part-2 => :[0] Hello Kafka 39
Part-5 => :[0] Hello Kafka 40
...
```
### Using the Id field as the key
If we specify an id <> 0 when running the producer, the id is used as the key
```java
private static void runProducer(int sendMessageCount, int waitMsInBetween, long id) throws Exception {
Long key = (id > 0) ? id : null;
try (Producer<Long, String> producer = createProducer()) {
for (int index = 0; index < sendMessageCount; index++) {
long time = System.currentTimeMillis();
ProducerRecord<Long, String> record
= new ProducerRecord<>(TOPIC, key, "[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now());
RecordMetadata metadata = producer.send(record).get();
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) "
+ "meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
```
So let's run it for id=`10`
```bash
mvn exec:java@producer -Dexec.args="1000 100 10"
```
### Changing to Asynchronous mode
The following class shows the same logic but this time using the asynchronous way for sending records to Kafka. The difference can be seen in the `runProducer` method.
```java
package com.trivadis.kafkaws.producer;
import java.time.LocalDateTime;
import java.util.Properties;
import java.util.concurrent.CountDownLatch;
import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.Producer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.clients.producer.ProducerRecord;
import org.apache.kafka.clients.producer.RecordMetadata;
import org.apache.kafka.common.serialization.LongSerializer;
import org.apache.kafka.common.serialization.StringSerializer;
public class KafkaProducerASync {
private final static String TOPIC = "test-java-topic";
private final static String BOOTSTRAP_SERVERS
= "dataplatform:9092, dataplatform:9093";
private static Producer<Long, String> createProducer() {
Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,
BOOTSTRAP_SERVERS);
props.put(ProducerConfig.CLIENT_ID_CONFIG, "KafkaExampleProducer");
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG,
LongSerializer.class.getName());
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,
StringSerializer.class.getName());
return new KafkaProducer<>(props);
}
private static void runProducer(int sendMessageCount, int waitMsInBetween, long id) throws Exception {
Long key = (id > 0) ? id : null;
final CountDownLatch countDownLatch = new CountDownLatch(sendMessageCount);
try (Producer<Long, String> producer = createProducer()) {
for (int index = 0; index < sendMessageCount; index++) {
long time = System.currentTimeMillis();
ProducerRecord<Long, String> record
= new ProducerRecord<>(TOPIC, key,
"[" + id + "] Hello Kafka " + LocalDateTime.now());
producer.send(record, (metadata, exception) -> {
long elapsedTime = System.currentTimeMillis() - time;
if (metadata != null) {
System.out.printf("[" + id + "] sent record(key=%s value=%s) "
+ "meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
} else {
exception.printStackTrace();
}
countDownLatch.countDown();
});
}
}
}
public static void main(String... args) throws Exception {
if (args.length == 0) {
runProducer(100, 10, 0);
} else {
runProducer(Integer.parseInt(args[0]), Integer.parseInt(args[1]), Long.parseLong(args[2]));
}
}
}
```
## Create a Kafka Consumer
Just like we did with the producer, you need to specify bootstrap servers. You also need to define a `group.id` that identifies which consumer group this consumer belongs. Then you need to designate a Kafka record key deserializer and a record value deserializer. Then you need to subscribe the consumer to the topic you created in the producer tutorial.
### Kafka Consumer with Automatic Offset Committing
First create a new Java Package `com.trivadis.kafkaws.consumer` in the folder **src/main/java**.
Create a new Java Class `KafkaConsumerAuto` in the package `com.trivadis.kafkaws.consumer` just created.
Add the following code to the empty class.
Now, that we imported the Kafka classes and defined some constants, let’s create a Kafka producer.
First imported the Kafka classes, define some constants and create the Kafka consumer.
```java
package com.trivadis.kafkaws.consumer;
import java.time.Duration;
import java.util.Collections;
import java.util.Properties;
import org.apache.kafka.clients.consumer.Consumer;
import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.KafkaConsumer;
import org.apache.kafka.common.serialization.LongDeserializer;
import org.apache.kafka.common.serialization.StringDeserializer;
public class KafkaConsumerAuto {
private final static String TOPIC = "test-java-topic";
private final static String BOOTSTRAP_SERVERS
= "dataplatform:9092,dataplatform:9093,dataplatform:9094";
private final static Duration CONSUMER_TIMEOUT = Duration.ofSeconds(1);
private static Consumer<Long, String> createConsumer() {
Properties props = new Properties();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ConsumerConfig.GROUP_ID_CONFIG, "KafkaConsumerAuto");
props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, true);
props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, 10000);
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, LongDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());
// Create the consumer using props.
Consumer<Long, String> consumer = new KafkaConsumer<>(props);
// Subscribe to the topic.
consumer.subscribe(Collections.singletonList(TOPIC));
return consumer;
}
```
With that in place, let's process the record with the Kafka Consumer.
```java
private static void runConsumer(int waitMsInBetween) throws InterruptedException {
final int giveUp = 100;
try (Consumer<Long, String> consumer = createConsumer()) {
int noRecordsCount = 0;
while (true) {
ConsumerRecords<Long, String> consumerRecords = consumer.poll(CONSUMER_TIMEOUT);
if (consumerRecords.isEmpty()) {
noRecordsCount++;
if (noRecordsCount > giveUp) {
break;
} else {
continue;
}
}
consumerRecords.forEach(record -> {
System.out.printf("%d - Consumer Record:(Key: %d, Value: %s, Partition: %d, Offset: %d)\n",
consumerRecords.count(), record.key(), record.value(),
record.partition(), record.offset());
try {
// Simulate slow processing
Thread.sleep(waitMsInBetween);
} catch (InterruptedException e) {
}
});
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("DONE");
}
```
Notice you use `ConsumerRecords` which is a group of records from a Kafka topic partition. The `ConsumerRecords` class is a container that holds a list of ConsumerRecord(s) per partition for a particular topic. There is one `ConsumerRecord` list for every topic partition returned by the `consumer.poll()`.
Next you define the main method. You can pass the amount of time the consumer spends for processing each record consumed.
```java
public static void main(String... args) throws Exception {
if (args.length == 0) {
runConsumer(10);
} else {
runConsumer(Integer.parseInt(args[0]));
}
}
```
The main method just calls `runConsumer`.
Before we run the consumer, let's add a new line to the `log4j.properties` configuration, just right after the `log4j.logger.org.apache.kafka=INFO` line.
```properties
log4j.logger.org.apache.kafka.clients.consumer.internals.ConsumerCoordinator=DEBUG
```
If will show a DEBUG message whenever the auto commit is executed.
Before we can run it, add the consumer to the `<executions>` section in the `pom.xml`.
```xml
<execution>
<id>consumer</id>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.trivadis.kafkaws.consumer.KafkaConsumerAuto</mainClass>
</configuration>
</execution>
```
Now run it using the `mvn exec:java` command.
```bash
mvn clean package -Dmaven.test.skip=true
mvn exec:java@consumer -Dexec.args="0"
```
**Note**: if your maven version does not support profiles, then you have to specify the main class as well: `mvn exec:java -Dexec.mainClass="com.trivadis.kafkaws.consumer.KafkaConsumerAuto" -Dexec.args="0"`
on the console you should see an output similar to the one below, with some Debug messages whenever the auto-commit is happening
```bash
1 - Consumer Record:(Key: null, Value: [0] Hello Kafka 399 => 2021-08-06T14:33:09.882489, Partition: 2, Offset: 317)

```
### Kafka Consumer with Manual Offset Control
Create a new Java Class `KafkaConsumerManual` in the package `com.trivadis.kafkaws.consumer` just created by copy-pasting from the class `KafkaConsumerAuto`.
Replace the `runConsumer()` method with the code below.
```java
private static void runConsumer(int waitMsInBetween) throws InterruptedException {
final int giveUp = 100;
try (Consumer<Long, String> consumer = createConsumer()) {
int noRecordsCount = 0;
while (true) {
ConsumerRecords<Long, String> consumerRecords = consumer.poll(CONSUMER_TIMEOUT);
if (consumerRecords.isEmpty()) {
noRecordsCount++;
if (noRecordsCount > giveUp) {
break;
}
}
consumerRecords.forEach(record -> {
System.out.printf("%d - Consumer Record:(Key: %d, Value: %s, Partition: %d, Offset: %d)\n",
consumerRecords.count(), record.key(), record.value(),
record.partition(), record.offset());
try {
// Simulate slow processing
Thread.sleep(waitMsInBetween);
} catch (InterruptedException e) {
}
});
consumer.commitAsync();
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("DONE");
}
```
Make sure to change the Consumer Group (`ConsumerConfig.GROUP_ID_CONFIG`) to `KafkaConsumerManual` and set the `ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG` to `false` in the `createConsumer()` method.
```java
props.put(ConsumerConfig.GROUP_ID_CONFIG, "KafkaConsumerManual");
props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, false);
```
## Try running Producer and Consumer
Run the consumer from your IDE or Terminal (Maven). Then run the producer from above from your IDE or Terminal (Maven). You should see the consumer get the records that the producer sent.
### Three Consumers in same group and one Producer sending 25 messages
Start the consumer 3 times by executing the following command in 3 different terminal windows.
```bash
mvn exec:java@consumer -Dexec.args="0"
```
and then start the producer
```bash
mvn exec:java@producer -Dexec.args="25 0 0"
```
#### Producer Output

```
**Questions**
- Which consumer owns partition 10?
- How many ConsumerRecords objects did Consumer 0 get?
- What is the next offset from Partition 11 that Consumer 2 should get?
- Why does each consumer get unique messages?
### Three Consumers in same group and one Producer sending 10 messages using key
Start the consumer 3 times by executing the following command in 3 different terminal windows.
```bash
mvn exec:java@consumer -Dexec.args="0"
```
and then start the producer (using 10 for the ID)
```bash
mvn exec:java@producer -Dexec.args="1000 100 10"
```
#### Producer Output
```bash
[10] sent record(key=10 value=[10] Hello Kafka 0) meta(partition=3, offset=289) time=326
[10] sent record(key=10 value=[10] Hello Kafka 1) meta(partition=3, offset=290) time=7

#### Consumer 3 Output (same consumer group)
nothing consumed
**Questions**
- Why is consumer 2 the only one getting data?
## Producing Kafka Headers
To produce a Kafka message with Kafka Headers, you have to first create a `List<Header>` instance and then headers of type `RecordHeader` as shown below (showing only the enhanced `runProducer` method):
```java
private static void runProducer(int sendMessageCount, int waitMsInBetween, long id) throws Exception {
Long key = (id > 0) ? id : null;
try (Producer<Long, String> producer = createProducer()) {
for (int index = 0; index < sendMessageCount; index++) {
long time = System.currentTimeMillis();
Integer partition = null;
Long timestamp = null;
// creating the Kafka Headers
List<Header> headers = new ArrayList<>();
headers.add(new RecordHeader("messageId", UUID.randomUUID().toString().getBytes(StandardCharsets.UTF_8)));
headers.add(new RecordHeader("source", "java-kafka".getBytes(StandardCharsets.UTF_8)));
ProducerRecord<Long, String> record = new ProducerRecord<>(TOPIC, partition, timestamp, key, "[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now(), headers);
RecordMetadata metadata = producer.send(record).get();
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) "
+ "meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
```
The `RecordHeader` constructor accepts a key of type `String` and a value of type `byte[]`.
## Changing the Value Serialization/Deserialization to use JSON
So far we have used the `StringSerializer`/`StringDeserializer` to serialize and deserialize a `java.lang.String` for the value of the message. This of course is not really useful in practice, as we want to send complex objects over Kafka. One way to do that is serializing a complex object as JSON on the producer side, send it and doing the opposite on the consumer side. This can be done with or without a schema. In this workshop we show the schema-less version with, in [Workshop Working with Avro and Java](../04a-working-with-avro-and-java) we will see how to work with Schema-based messages together with a schema registry.
### Add Maven dependency
For the JSON serialization we will be using the Jackson library. So let's add that as a dependency to the `pom.xml`
```xml
<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.12.4</version>
</dependency>
```
### Create a Notification class
Create a new Java class which will hold our notification in 3 different fields. We annotate these 3 fields with `@JsonProperty` so that they will be serialized later.
```java
package com.trivadis.kafkaws;
import com.fasterxml.jackson.annotation.JsonProperty;
public class Notification {
@JsonProperty
private long id;
@JsonProperty
private String message;
@JsonProperty
private String createdAt;
public Notification() {};
public Notification(long id, String message, String createdAt) {
this.id = id;
this.message = message;
this.createdAt = createdAt;
}
public long getId() {
return id;
}
public String getMessage() {
return message;
}
public String getCreatedAt() {
return createdAt;
}
@Override
public String toString() {
return "Notification{" +
"id=" + id +
", message='" + message + '\'' +
", createdAt='" + createdAt + '\'' +
'}';
}
}
```
### Create the custom JsonSerializer and JsonDeserializer implemenations
Next we have to create the custom serializer/deseralizer handling the JSON serialization and deserialization.
First create a new package `serde`.
Create a new class for the serializer in the `serde` package
```java
package com.trivadis.kafkaws.serde;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.trivadis.kafkaws.Notification;
import org.apache.kafka.common.errors.SerializationException;
import org.apache.kafka.common.serialization.Serializer;
import java.util.Map;
public class JsonSerializer<T> implements Serializer<T> {
private final ObjectMapper objectMapper = new ObjectMapper();
public JsonSerializer() {
//Nothing to do
}
@Override
public void configure(Map<String, ?> config, boolean isKey) {
//Nothing to Configure
}
@Override
public byte[] serialize(String topic, T data) {
if (data == null) {
return null;
}
try {
return objectMapper.writeValueAsBytes(data);
} catch (JsonProcessingException e) {
throw new SerializationException("Error serializing JSON message", e);
}
}
@Override
public void close() {
}
}
```
And another new class for the deserializer also in the `serde` package
```java
package com.trivadis.kafkaws.serde;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.apache.kafka.common.serialization.Deserializer;
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import java.util.Map;
public class JsonDeserializer<T> implements Deserializer<T> {
private Logger logger = LogManager.getLogger(this.getClass());
private Class <T> type;
public JsonDeserializer(Class type) {
this.type = type;
}
@Override
public void configure(Map map, boolean b) {
}
@Override
public T deserialize(String s, byte[] bytes) {
ObjectMapper mapper = new ObjectMapper();
T obj = null;
try {
obj = mapper.readValue(bytes, type);
} catch (Exception e) {
logger.error(e.getMessage());
}
return obj;
}
@Override
public void close() {
}
}
```
### Create the new Producer using the JsonSerializer
Create a new class `KafkaProducerJson` next to the exiting producer implementation
```java
package com.trivadis.kafkaws.producer;
import com.trivadis.kafkaws.Notification;
import com.trivadis.kafkaws.serde.JsonSerializer;
import org.apache.kafka.clients.producer.*;
import org.apache.kafka.common.serialization.LongSerializer;
import java.time.LocalDateTime;
import java.util.Properties;
public class KafkaProducerJson {
private final static String TOPIC = "test-java-json-topic";
private final static String BOOTSTRAP_SERVERS
= "dataplatform:9092,dataplatform:9093";
private static Producer<Long, Notification> createProducer() {
Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ProducerConfig.CLIENT_ID_CONFIG, "KafkaExampleProducer");
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG,
LongSerializer.class.getName());
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,
JsonSerializer.class.getName());
return new KafkaProducer<>(props);
}
private static void runProducer(int sendMessageCount, int waitMsInBetween, long id) throws Exception {
Long key = (id > 0) ? id : null;
try (Producer<Long, Notification> producer = createProducer()) {
for (int index = 0; index < sendMessageCount; index++) {
long time = System.currentTimeMillis();
Notification notification = new Notification(id, "[" + id + "] Hello Kafka " + index, LocalDateTime.now().toString());
ProducerRecord<Long, Notification> record
= new ProducerRecord<>(TOPIC, key, notification);
RecordMetadata metadata = producer.send(record).get();
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) "
+ "meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
public static void main(String... args) throws Exception {
if (args.length == 0) {
runProducer(100, 10, 0);
} else {
runProducer(Integer.parseInt(args[0]), Integer.parseInt(args[1]), Long.parseLong(args[2]));
}
}
}
```
Changes to the previous producer implementation are in the configuration were we use the `JsonSerializer`
```java
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,
JsonSerializer.class.getName());
```
and with all the generics, where we use `<Long, Notifcation>` instead of `<Long, String>`. Additionally of course for sending the value of the Kafka record, we create a `Notification` object.
We also use another topic `test-java-json-topic`, so we clearly separate the different messages.
### Creating the new Kafka Topic
We show a shortcut version here, instead of first "connecting" to the container and then issuing the `kafka-topics` command, we do it in one
```bash
docker exec -ti kafka-1 kafka-topics --create \
--replication-factor 3 \
--partitions 8 \
--topic test-java-topic \
--zookeeper zookeeper-1:2181
```
### Testing the JsonProducer
To test the producer, let's also add a new section to the `executions` of the `pom.xml`
```xml
<execution>
<id>producer-json</id>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.trivadis.kafkaws.producer.KafkaProducerJson</mainClass>
</configuration>
</execution>
```
Now run it using the `mvn exec:java` command. The arguments again tell to create `100` messages, with a delay of `100ms` inbetween and using `null` for the key:
```bash
mvn clean package -Dmaven.test.skip=true
mvn exec:java@producer-json -Dexec.args="100 100 0"
```
Use `kafkacat` to consume the messages from the topic `test-java-json-topic`.
```bash
kafkacat -b dataplatform -t test-java-json-topic -q
```
you can see the messages are all formated as JSON documents
```bash
{"id":0,"message":"[0] Hello Kafka 750","createdAt":"2021-08-06T18:38:10.679026"}
{"id":0,"message":"[0] Hello Kafka 752","createdAt":"2021-08-06T18:38:10.892763"}
{"id":0,"message":"[0] Hello Kafka 755","createdAt":"2021-08-06T18:38:11.207189"}
{"id":0,"message":"[0] Hello Kafka 758","createdAt":"2021-08-06T18:38:11.527921"}
{"id":0,"message":"[0] Hello Kafka 766","createdAt":"2021-08-06T18:38:12.379010"}
{"id":0,"message":"[0] Hello Kafka 776","createdAt":"2021-08-06T18:38:13.442783"}
{"id":0,"message":"[0] Hello Kafka 781","createdAt":"2021-08-06T18:38:13.973201"}
```
This completes the producer, let's now implement the corresponding consumer.
### Create the Consumer
Create a new class `KafkaConsumerJson` next to the exiting consumer implementation. We use the implementation of the non-auto-commit version and adapt it
```java
package com.trivadis.kafkaws.consumer;
import com.trivadis.kafkaws.Notification;
import com.trivadis.kafkaws.serde.JsonDeserializer;
import org.apache.kafka.clients.consumer.Consumer;
import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.KafkaConsumer;
import org.apache.kafka.common.serialization.LongDeserializer;
import java.time.Duration;
import java.util.Collections;
import java.util.Properties;
public class KafkaConsumerJson {
private final static String TOPIC = "test-java-json-topic";
private final static String BOOTSTRAP_SERVERS
= "dataplatform:9092,dataplatform:9093,dataplatform:9094";
private final static Duration CONSUMER_TIMEOUT = Duration.ofSeconds(1);
private static Consumer<Long, Notification> createConsumer() {
Properties props = new Properties();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ConsumerConfig.GROUP_ID_CONFIG, "KafkaConsumerJson");
props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, false);
props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, 10000);
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, LongDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JsonDeserializer.class.getName());
// Create the consumer using props.
Consumer<Long, Notification> consumer = new KafkaConsumer<>(props, new LongDeserializer(), new JsonDeserializer<Notification>(Notification.class));
// Subscribe to the topic.
consumer.subscribe(Collections.singletonList(TOPIC));
return consumer;
}
private static void runConsumer(int waitMsInBetween) throws InterruptedException {
final int giveUp = 100;
try (Consumer<Long, Notification> consumer = createConsumer()) {
int noRecordsCount = 0;
while (true) {
ConsumerRecords<Long, Notification> consumerRecords = consumer.poll(CONSUMER_TIMEOUT);
if (consumerRecords.isEmpty()) {
noRecordsCount++;
if (noRecordsCount > giveUp) {
break;
} else {
continue;
}
}
consumerRecords.forEach(record -> {
System.out.printf("%d - Consumer Record:(Key: %d, Value: %s, Partition: %d, Offset: %d)\n",
consumerRecords.count(), record.key(), record.value(),
record.partition(), record.offset());
try {
// Simulate slow processing
Thread.sleep(waitMsInBetween);
} catch (InterruptedException e) {
}
});
consumer.commitAsync();
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("DONE");
}
public static void main(String... args) throws Exception {
if (args.length == 0) {
runConsumer(10);
} else {
runConsumer(Integer.parseInt(args[0]));
}
}
}
```
Changes to the previous consumer implementation are again in the configuration were we use the `JsonDeserializer`
```java
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JsonDeserializer.class.getName());
```
Additionally when we create the `KafkaConsumer`, we have to initialze an instance of `JsonDeserializer` and pass it as an argument to the constructor
```java
Consumer<Long, Notification> consumer = new KafkaConsumer<>(props, new LongDeserializer(), new JsonDeserializer<Notification>(Notification.class));
```
And again we change all the generics, where we use `<Long, Notifcation>` instead of `<Long, String>`.
### Testing the JsonProducer
To test the consumer, let's also add a new section to the `executions` of the `pom.xml`
```xml
<execution>
<id>consumer-json</id>
<goals>
<goal>java</goal>
</goals>
<configuration>
<mainClass>com.trivadis.kafkaws.consumer.KafkaConsumerJson</mainClass>
</configuration>
</execution>
```
Now run it using the `mvn exec:java` command
```bash
mvn clean package -Dmaven.test.skip=true
mvn exec:java@consumer-json -Dexec.args="0"
```
and you should see the `toString()` output of the `Notification` instances, similar to the one shown below
```bash
190 - Consumer Record:(Key: null, Value: Notification{id=0, message='[0] Hello Kafka 742', createdAt='2021-08-06T18:38:09.825359'}, Partition: 1, Offset: 239)
190 - Consumer Record:(Key: null, Value: Notification{id=0, message='[0] Hello Kafka 745', createdAt='2021-08-06T18:38:10.145740'}, Partition: 1, Offset: 240)
190 - Consumer Record:(Key: null, Value: Notification{id=0, message='[0] Hello Kafka 753', createdAt='2021-08-06T18:38:10.999308'}, Partition: 1, Offset: 241)
190 - Consumer Record:(Key: null, Value: Notification{id=0, message='[0] Hello Kafka 761', createdAt='2021-08-06T18:38:11.847942'}, Partition: 1, Offset: 242)
190 - Consumer Record:(Key: null, Value: Notification{id=0, message='[0] Hello Kafka 768', createdAt='2021-08-06T18:38:12.591090'}, Partition: 1, Offset: 243)
190 - Consumer Record:(Key: null, Value: Notification{id=0, message='[0] Hello Kafka 774', createdAt='2021-08-06T18:38:13.233265'}, Partition: 1, Offset: 244)
```

<file_sep># Manipulating Consumer Offsets
In this workshop we will learn how to manipulate the consumer offsets to reset a consumer to a certain place.
We will be using the `kafka-consumer-groups` CLI.
## Create some fresh messages
We will be using the Java client from [Workshop 4 - Working with Kafka from Java](../04-producing-consuming-kafka-with-java/README.md) to produce and consume some messages first. To assure that we start from scratch, lets first remove the data from the topic by recreating it.
You can also use the C# or Python implementation instead of the Java one. Just make sure to adapt the topic and the consumer group.
```bash
docker exec -ti kafka-1 kafka-topics --delete --topic test-java-topic --bootstrap-server kafka-1:19092,kafka-2:19093
docker exec kafka-1 kafka-topics --create \
--replication-factor 3 \
--partitions 8 \
--topic test-java-topic \
--bootstrap-server kafka-1:19092,kafka-2:19093
```
By that we can also make sure, that the offsets will again start at 0.
Start the a producer to produce 1000 messages with a delay of 100ms between sending each message. We deliberately only use one partition by specifying a key (`1`).
Make sure to use the synchronous producer!
```bash
mvn exec:java@producer -Dexec.args="1000 100 1"
```
in the log check the output for a timestamp to use for the reset
```
[1] sent record(key=1 value=[1] Hello Kafka 428 => 2021-09-22T08:19:49.412417) meta(partition=4, offset=428) time=2
[1] sent record(key=1 value=[1] Hello Kafka 429 => 2021-09-22T08:19:49.519555) meta(partition=4, offset=429) time=4
[1] sent record(key=1 value=[1] Hello Kafka 430 => 2021-09-22T08:19:49.625616) meta(partition=4, offset=430) time=5
[1] sent record(key=1 value=[1] Hello Kafka 431 => 2021-09-22T08:19:49.732601) meta(partition=4, offset=431) time=6
[1] sent record(key=1 value=[1] Hello Kafka 432 => 2021-09-22T08:19:49.843735) meta(partition=4, offset=432) time=3
[1] sent record(key=1 value=[1] Hello Kafka 433 => 2021-09-22T08:19:49.951001) meta(partition=4, offset=433) time=3
[1] sent record(key=1 value=[1] Hello Kafka 434 => 2021-09-22T08:19:50.057701) meta(partition=4, offset=434) time=5
[1] sent record(key=1 value=[1] Hello Kafka 435 => 2021-09-22T08:19:50.166302) meta(partition=4, offset=435) time=2
[1] sent record(key=1 value=[1] Hello Kafka 436 => 2021-09-22T08:19:50.273466) meta(partition=4, offset=436) time=3
[1] sent record(key=1 value=[1] Hello Kafka 437 => 2021-09-22T08:19:50.378912) meta(partition=4, offset=437) time=3
```
We will be using `2021-09-22T08:19:50.057701` later to reset to. So we expect the offset after the reset will be `434`.
## Consume Messages
Now let's consume all these messages once:
```bash
mvn exec:java@consumer -Dexec.args="0"
```
By that we are sure to be at the end of topic `test-java-topic`.
## Resetting offsets
To change or reset the offsets of a consumer group, the `kafka-consumer-groups` utility has been created. You need specify the topic, consumer group and use the `--reset-offsets` flag to change the offset.
We can also find it in any of the brokers, similar to the `kafka-topics` CLI. Executing
```bash
docker exec -ti kafka-1 kafka-consumer-groups
```
will display the help page with all the available options
```
$ docker exec -ti kafka-1 kafka-consumer-groups
Missing required argument "[bootstrap-server]"
Option Description
------ -----------
--all-groups Apply to all consumer groups.
--all-topics Consider all topics assigned to a
group in the `reset-offsets` process.
--bootstrap-server <String: server to REQUIRED: The server(s) to connect to.
connect to>
--by-duration <String: duration> Reset offsets to offset by duration
from current timestamp. Format:
'PnDTnHnMnS'
--command-config <String: command Property file containing configs to be
config property file> passed to Admin Client and Consumer.
--delete Pass in groups to delete topic
partition offsets and ownership
information over the entire consumer
group. For instance --group g1 --
group g2
--delete-offsets Delete offsets of consumer group.
Supports one consumer group at the
time, and multiple topics.
--describe Describe consumer group and list
offset lag (number of messages not
yet processed) related to given
group.
--dry-run Only show results without executing
changes on Consumer Groups.
Supported operations: reset-offsets.
--execute Execute operation. Supported
operations: reset-offsets.
--export Export operation execution to a CSV
file. Supported operations: reset-
offsets.
--from-file <String: path to CSV file> Reset offsets to values defined in CSV
file.
--group <String: consumer group> The consumer group we wish to act on.
--help Print usage information.
--list List all consumer groups.
--members Describe members of the group. This
option may be used with '--describe'
and '--bootstrap-server' options
only.
Example: --bootstrap-server localhost:
9092 --describe --group group1 --
members
--offsets Describe the group and list all topic
partitions in the group along with
their offset lag. This is the
default sub-action of and may be
used with '--describe' and '--
bootstrap-server' options only.
Example: --bootstrap-server localhost:
9092 --describe --group group1 --
offsets
--reset-offsets Reset offsets of consumer group.
Supports one consumer group at the
time, and instances should be
inactive
Has 2 execution options: --dry-run
(the default) to plan which offsets
to reset, and --execute to update
the offsets. Additionally, the --
export option is used to export the
results to a CSV format.
You must choose one of the following
reset specifications: --to-datetime,
--by-period, --to-earliest, --to-
latest, --shift-by, --from-file, --
to-current.
To define the scope use --all-topics
or --topic. One scope must be
specified unless you use '--from-
file'.
--shift-by <Long: number-of-offsets> Reset offsets shifting current offset
by 'n', where 'n' can be positive or
negative.
--state [String] When specified with '--describe',
includes the state of the group.
Example: --bootstrap-server localhost:
9092 --describe --group group1 --
state
When specified with '--list', it
displays the state of all groups. It
can also be used to list groups with
specific states.
Example: --bootstrap-server localhost:
9092 --list --state stable,empty
This option may be used with '--
describe', '--list' and '--bootstrap-
server' options only.
--timeout <Long: timeout (ms)> The timeout that can be set for some
use cases. For example, it can be
used when describing the group to
specify the maximum amount of time
in milliseconds to wait before the
group stabilizes (when the group is
just created, or is going through
some changes). (default: 5000)
--to-current Reset offsets to current offset.
--to-datetime <String: datetime> Reset offsets to offset from datetime.
Format: 'YYYY-MM-DDTHH:mm:SS.sss'
--to-earliest Reset offsets to earliest offset.
--to-latest Reset offsets to latest offset.
--to-offset <Long: offset> Reset offsets to a specific offset.
--topic <String: topic> The topic whose consumer group
information should be deleted or
topic whose should be included in
the reset offset process. In `reset-
offsets` case, partitions can be
specified using this format: `topic1:
0,1,2`, where 0,1,2 are the
partition to be included in the
process. Reset-offsets also supports
multiple topic inputs.
--verbose Provide additional information, if
any, when describing the group. This
option may be used with '--
offsets'/'--members'/'--state' and
'--bootstrap-server' options only.
Example: --bootstrap-server localhost:
9092 --describe --group group1 --
members --verbose
--version Display Kafka version.
```
### How to find the current consumer offset?
Use the kafka-consumer-groups along with the consumer group id followed by a describe
```bash
docker exec -ti kafka-1 kafka-consumer-groups --bootstrap-server kafka-2:19093 --group "KafkaConsumerAuto" --verbose --describe
```
You will see 2 entries related to offsets – CURRENT-OFFSET and LOG-END-OFFSET for the partitions in the topic for that consumer group. CURRENT-OFFSET is the current offset for the partition in the consumer group.
```
$ docker exec -ti kafka-1 kafka-consumer-groups --bootstrap-server kafka-1:19093 --group "KafkaConsumerAuto" --verbose --describe
Consumer group 'KafkaConsumerAuto' has no active members.
GROUP TOPIC PARTITION CURRENT-OFFSET LOG-END-OFFSET LAG CONSUMER-ID HOST CLIENT-ID
KafkaConsumerAuto test-java-topic 6 0 0 0 consumer-KafkaConsumerAuto-1-e74b46d4-2c43-4278-a006-ae51c779a1e2 /192.168.142.1 consumer-KafkaConsumerAuto-1
KafkaConsumerAuto test-java-topic 1 0 0 0 consumer-KafkaConsumerAuto-1-e74b46d4-2c43-4278-a006-ae51c779a1e2 /192.168.142.1 consumer-KafkaConsumerAuto-1
KafkaConsumerAuto test-java-topic 7 0 0 0 consumer-KafkaConsumerAuto-1-e74b46d4-2c43-4278-a006-ae51c779a1e2 /192.168.142.1 consumer-KafkaConsumerAuto-1
KafkaConsumerAuto test-java-topic 0 0 0 0 consumer-KafkaConsumerAuto-1-e74b46d4-2c43-4278-a006-ae51c779a1e2 /192.168.142.1 consumer-KafkaConsumerAuto-1

KafkaConsumerAuto test-java-topic 3 0 0 0 consumer-KafkaConsumerAuto-1-e74b46d4-2c43-4278-a006-ae51c779a1e2 /192.168.142.1 consumer-KafkaConsumerAuto-1
KafkaConsumerAuto test-java-topic 5 0 0 0 consumer-KafkaConsumerAuto-1-e74b46d4-2c43-4278-a006-ae51c779a1e2 /192.168.142.1 consumer-KafkaConsumerAuto-1
KafkaConsumerAuto test-java-topic 2 0 0 0 consumer-KafkaConsumerAuto-1-e74b46d4-2c43-4278-a006-ae51c779a1e2 /192.168.142.1 consumer-KafkaConsumerAuto-1
```
We can see that all messages were sent to partition 4.
### Reset offsets to a timestamp
Let's reset the offsets to the timestamp `2021-09-22T08:19:50.057701` we noted above, by rounding it down to the minute. You also have to adapt the timestamp to UTC timestamp (currently -2)
```bash
docker exec -ti kafka-1 kafka-consumer-groups --bootstrap-server kafka-1:19092 --group "KafkaConsumerAuto" --reset-offsets --to-datetime 2021-09-22T06:19:50.00Z --topic test-java-topic --execute
```
You should see the `NEW-OFFST` changed to `434`
```bash
docker exec -ti kafka-1 kafka-consumer-groups --bootstrap-server kafka-1:19092 --group "KafkaConsumerAuto" --reset-offsets --to-datetime 2021-09-22T06:19:50.00Z --topic test-java-topic --execute
GROUP TOPIC PARTITION NEW-OFFSET
KafkaConsumerAuto test-java-topic 6 0
KafkaConsumerAuto test-java-topic 1 0
KafkaConsumerAuto test-java-topic 7 0
KafkaConsumerAuto test-java-topic 0 0
KafkaConsumerAuto test-java-topic 4 434
KafkaConsumerAuto test-java-topic 3 0
KafkaConsumerAuto test-java-topic 5 0
KafkaConsumerAuto test-java-topic 2 0
```
Now lets rerun the consumer and you should see the first message being consumed to be the following one
```
500 - Consumer Record:(Key: 1, Value: [1] Hello Kafka 434 => 2021-09-22T08:19:50.057701, Partition: 4, Offset: 434)
5
```
### Reset offsets to offset to earliest
This command resets the offsets to earliest (oldest) offset available in the topic.
```bash
docker exec -ti kafka-1 kafka-consumer-groups --bootstrap-server kafka-1:19092 --group "KafkaConsumerAuto" --reset-offsets --to-earliest --topic test-java-topic --execute
```
Rerun the consumer to check that again all messages are consumed.
There are many other resetting options, run `kafka-consumer-groups` for details
```
--shift-by
--to-current
--to-latest
--to-offset
--by-duration
```

# Creating and visualising ADRs with log4brains
This recipe will show how to create and visualise Architecture Decision Records (ADR) using [log4brains](https://github.com/thomvaill/log4brains).
If you want to know more on the concept of Architecture Decision Records (ADRs), there is a [Trivadis Platform Factory whitepaper](https://tvdit.sharepoint.com/:b:/r/sites/PlatformFactoryPublic/Shared%20Documents/Architecture%20Blueprints/Modern%20Data%20Architecture/wp-architecture-decision-record-v1.0d.pdf?csf=1&web=1&e=0BP76w) available (currently only in german).
## Initialise a platform
First [initialise a platys-supported data platform](../../getting-started) with the following services enabled
```bash
platys init --enable-services LOG4BRAINS,WETTY,MARKDOWN_VIEWER -s trivadis/platys-modern-data-platform -w 1.16.0
```
add the following property to the `config.yml`
```bash
LOG4BRAINS_adr_source_dir: './adr'
```
Now create the `adr` folder
```
mkdir adr
```
Now generate and start the data platform.
```bash
platys gen
docker-compose up -d
```
For creating the ADR documents, you also may want to install log4brains locally (you need to have Node.js installed)
```
npm install -g log4brains
```
As an alternative you can also use the `log4brains` docker image and use a `docker run` for each of the commands (replace `<cmd>` by the log4brains command to use).
```
docker run -ti -v ${PWD}:/workdir thomvaill/log4brains <cmd>
```
## Create the log4brains ADR project
Navigate to the `adr` folder created above
```
cd adr
log4brains init
```
if you want to use the docker image instead of the local log4brains installation, then perform
```
cd adr
docker run -ti -v ${PWD}:/workdir thomvaill/log4brains init
```
Answer the question asked by the tool as shown below
We can see that the following folder structure has been created.
```
docker@ubuntu:~/platys-cookbook/adr$ tree
.
└── docs
└── adr
├── 20210412-use-log4brains-to-manage-the-adrs.md
├── 20210412-use-markdown-architectural-decision-records.md
├── index.md
├── README.md
└── template.md
2 directories, 5 files
```
With the init 2 sample ADRs were automatically created. They can be removed later.
Now with the ADR project being initialised, can restart the `log4brains` container
```
docker restart log4brains
```
Now navigate to <http://dataplatform:4004> and you should see two ADRs being rendered as a Web application.
## Create a new ADR
Navigate to the `adr` folder created above and run the `adr new` command
```
cd adr
log4brains adr new
```
if you want to use the docker image instead of the local log4brains installation, then perform
```
cd adr
docker run -ti -v ${PWD}:/workdir thomvaill/log4brains adr new
```
Answer the questions asked by the tool, such as the title and if the ADR is a new one or should supersede an existing one.
```
docker@ubuntu:~/platys-cookbook/adr$ docker run -ti -v ${PWD}:/workdir thomvaill/log4brains adr new
? Title of the solved problem and its solution? This is my first ADR
? Does this ADR supersede a previous one? No
✔ New ADR created: docs/adr/20210412-this-is-my-first-adr.md
? How would you like to edit it? Later
```
Because of the preview mode and its hot reload feature, the UI will automatically reflect the newly created ADR.
Edit the file `docs/adr/20210412-this-is-my-first-adr.md` in the Editor of your choice to define the ADR.
## Building a static website
Navigate to the `adr` folder created above and run the `build` command
```
cd adr
docker run -ti -v ${PWD}:/workdir thomvaill/log4brains build
```
After a while you should see the following output
```
docker@ubuntu:~/platys-cookbook/adr$ docker run -ti -v "${PWD}":/workdir thomvaill/log4brains build
Building Log4brains...
info - Creating an optimized production build
info - Collecting page data
info - Finalizing page optimization
[====] Generating search index... Done
✔ Your Log4brains static site was successfully generated to .log4brains/out with a total of 3 ADRs
```
The static website is available in `.log4brains/out`. Consult the [Log4brains GitHub](https://github.com/thomvaill/log4brains#-cicd-configuration-examples) to see examples on how deploy it to various static hosting services.

## List topics
To list detailed descriptions of all topics (internal and user created topics), use the topics endpoint GET `/clusters/{cluster_id}/topics/`
```bash
curl --silent -X GET http://dataplatform:18086/v3/clusters/${CLUSTER_ID}/topics | jq
```
to show only the topic names, use a grep on the output of `jq`
```bash
curl --silent -X GET http://dataplatform:18086/v3/clusters/${CLUSTER_ID}/topics | jq | grep '.topic_name'
```
## Describe a topic
To get a full description of a specified topic, use the topics endpoint GET `/clusters/{cluster_id}/topics/{topic_name}`
```bash
curl --silent -X GET http://dataplatform:18086/v3/clusters/${CLUSTER_ID}/topics/rest-proxy-topic | jq
```
## Working with JSON data
### Produce JSON
```bash
curl --silent -X POST 'http://dataplatform:18086/topics/rest-proxy-topic' \
--header 'Content-Type: application/vnd.kafka.json.v2+json' \
--data-raw '{
"records": [
{
"key": "1",
"value": {
"id": 1,
"customerCode": 1,
"telephone": "888582158",
"email": "<EMAIL>",
"language": "EN"
}
}
]
}'
```
### Consume JSON
1. create a consumer `ci1` belonging to consumer group `cg1`.
Specify `auto.offset.reset` to be `earliest` so it starts at the beginning of the topic.
```bash
curl --silent -X POST \
-H "Content-Type: application/vnd.kafka.v2+json" \
--data '{"name": "ci1", "format": "json", "auto.offset.reset": "earliest"}' \
http://dataplatform:18086/consumers/cg1 | jq .
```
Result:
```
{
"instance_id": "ci1",
"base_uri": "http://kafka-rest-1:8086/consumers/cg1/instances/ci1"
}
```
2. Subscribe the consumer to topic `rest-proxy-topic`
```bash
curl --silent -X POST \
-H "Content-Type: application/vnd.kafka.v2+json" \
--data '{"topics":["rest-proxy-topic"]}' \
http://dataplatform:18086/consumers/cg1/instances/ci1/subscription | jq .
```
3. Consume data using the base URL in the first reponse.
```bash
curl --silent -X GET \
-H "Accept: application/vnd.kafka.json.v2+json" \
http://dataplatform:18086/consumers/cg1/instances/ci1/records | jq .
```
4. Close the consumer with a DELETE to make it leave the group and clean up its resources
```bash
curl --silent -X DELETE \
-H "Content-Type: application/vnd.kafka.v2+json" \
http://dataplatform:18086/consumers/cg1/instances/ci1 | jq .
```
## Working with Avro data
### Create a new topic
To create a topic, use the topics endpoint POST `/clusters/{cluster_id}/topics` as shown below.
```bash
curl --silent -X POST -H "Content-Type: application/json" \
--data '{"topic_name": "rest-proxy-avro-topic", "replication_factor":"3", "partitions_count": "8"}' \
http://dataplatform:18086/v3/clusters/${CLUSTER_ID}/topics | jq
```
### Register the Avro Schema
Navigate to http://dataplatform:28102 and register the following Avro schema under subject `rest-proxy-avro-topic-value`:
```json
{
"type": "record",
"name": "Customer",
"namespace": "com.trivadis.kafkaws.sample",
"doc": "This is a sample Avro schema to get you started. Please edit",
"fields": [
{
"name": "id",
"type": "long"
},
{
"name": "customerCode",
"type": "long"
},
{
"name": "telephone",
"type": "string"
},
{
"name": "email",
"type": "string"
},
{
"name": "language",
"type": "string"
}
]
}
```
Set the variable `SCHEMA_ID` to the value of the schema ID of the schema registry
```bash
export SCHEMA_ID=$(curl -X GET "http://dataplatform:8081/subjects/rest-proxy-avro-topic-value/versions/latest" | jq '.id')
```
### Produce Avro
Produce three Avro messages to the topic `rest-proxy-avro-topic`
```bash
curl --silent -X POST \
-H "Content-Type: application/vnd.kafka.avro.v2+json" \
-H "Accept: application/vnd.kafka.v2+json" \
--data '{"value_schema_id": '"$SCHEMA_ID"', "records": [{"value": {
"id": 1,
"customerCode": 1,
"telephone": "888582158",
"email": "<EMAIL>",
"language": "EN"
} }]}' \
"http://dataplatform:18086/topics/rest-proxy-avro-topic" | jq .
```
Result:
```
{
"offsets": [
{
"partition": 1,
"offset": 0,
"error_code": null,
"error": null
}
],
"key_schema_id": null,
"value_schema_id": 3
}
```
### Consume Avro
1. Create a consumer `ci2` belonging to consumer group `cg2`. Specify `auto.offset.reset` to be earliest so it starts at the beginning of the topic.
```bash
curl --silent -X POST \
-H "Content-Type: application/vnd.kafka.v2+json" \
--data '{"name": "ci2", "format": "avro", "auto.offset.reset": "earliest"}' \
http://dataplatform:18086/consumers/cg2 | jq .
```
Result:
```
{
"instance_id": "ci2",
"base_uri": "http://kafka-rest-1:8086/consumers/cg2/instances/ci2"
}
```
2. Subscribe the consumer to topic `rest-proxy-avro-topic`
```bash
curl --silent -X POST \
-H "Content-Type: application/vnd.kafka.v2+json" \
--data '{"topics":["rest-proxy-avro-topic"]}' \

The Apache™ Hadoop® project develops open-source software for reliable, scalable, distributed computing.
The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures.

}<file_sep># Working with Kafka from .NET
In this workshop we will learn how to produce and consume messages using the [Kafka .NET API](https://docs.confluent.io/clients-confluent-kafka-dotnet/current/overview.html).
We will show how to build the .NET application using the Visual Code IDE, but any other IDE or just a simple Editor would be fine as well.
We assume that .NET Core is installed on your client as well as Visual Code with the C# extension (ms-dotnettools.csharp) enabled. We will use the .NET CLI (`dotnet`) for creating projects and running the code.
## Create the project structure
We will create two projects, one acting as the producer to Kafka and the other one as the consumer from Kafka.
First create the workspace folder, which will hold our projects and navigate into it.
```bash
mkdir kafka-dotnet-workshop
cd kafka-dotnet-workshop
```
Now let's create the producer project
```bash
dotnet new console -o producer
```
Now start Visual Code, on Linux if installed using the [following documentation](https://code.visualstudio.com/docs/setup/linux), then it can be started with `code`.
```bash
code
```
On the **Getting Started** page, click on **Open...** and select the `kafka-dotnet-workspace` folder created above. Confirm the **Required assets to build and debug are missing from ... Add them?** message pop-up with **Yes**. Open a Terminal in Visual Code over the menu **Terminal** | **New Terminal**.
We are now ready to add code to the classes which have been created with the `dotnet new` command.
But before we do that, let's create the topic we will use to produce to and to consume from.
### Creating the necessary Kafka Topic
We will use the topic `test-dotnet-topic` in the Producer and Consumer code below. Because `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
Connect to the `kafka-1` container
```
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```
kafka-topics --create \
--replication-factor 3 \
--partitions 12 \
--topic test-dotnet-topic \
--bootstrap-server kafka-1:19092,kafka-2:19093
```
Cross check that the topic has been created.
```
kafka-topics --list --bootstrap-server kafka-1:19092
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing a **Kafka Producer**.
## Create a Kafka Producer
To communicate with Kafka, we need to use the [**confluent-kafka-dotnet**](https://docs.confluent.io/clients-confluent-kafka-dotnet/current/overview.html) .NET library].
The reference the library from the .NET Core project, execute the following command from within the `kafka-dotnet-workspace` folder.
```
dotnet add producer package Confluent.Kafka
```
The following reference will be added to project metadata
```
<Project Sdk="Microsoft.NET.Sdk">
...
<ItemGroup>
<PackageReference Include="Confluent.Kafka" Version="1.8.2" />
</ItemGroup>
</Project>
```
Now let's add the code for producing messages to the Kafka topic. Navigate to the `Program.cs` C# class in the `producer` project and rename it to `KafkaProducer.cs` and then open it in the editor.
Add the following directives on the top with the class and the following two constants for the Broker List and the Topic name:
```csharp
using System;
using System.Threading;
using Confluent.Kafka;
namespace producer
{
class Program
{
const string brokerList = "dataplatform:9092,dataplatform:9093";
const string topicName = "test-dotnet-topic";
}
}
```
Add the following main method to the class:
```csharp
private static async Task Main(string[] args)
{
long startTime = DateTimeOffset.Now.ToUnixTimeMilliseconds();
if (args.Length == 0)
{
runProducerSync(100, 10, 0);
}
else
{
runProducerSync(int.Parse(args[0]), int.Parse(args[1]), int.Parse(args[2]));
}
long endTime = DateTimeOffset.Now.ToUnixTimeMilliseconds();
Console.WriteLine("Producing all records took : " + (endTime - startTime) + " ms = (" + (endTime - startTime) / 1000 + " sec)");
}
// place the runProducerXXXX methods below
```
The `Main()` method accepts 3 parameters, the number of messages to produce, the time in ms to wait in-between sending each message and the ID of the producer.
Add the following additional method for implementing the Kafka producer. To write messages to Kafka, we can either use the `ProduceAsync` or `Produce` method.
### Produce Synchronously with a `Null` key
We will first use the `ProducerAsync` method in a synchronous way using the `await` operator. We are producing just a value and leave the key empty (`Null`).
```csharp
static async Task runProducerSync(int totalMessages, int waitMsInBetween, int id)
{
var config = new ProducerConfig { BootstrapServers = brokerList };
// Create the Kafka Producer
using (var producer = new ProducerBuilder<Null, string>(config).Build())
{
for (int index = 0; index < totalMessages; index++)
{
// Construct the message value
string value = "[" + index + ":" + id + "] Hello Kafka " + DateTimeOffset.Now;
// send the message to Kafka
var deliveryReport = await producer.ProduceAsync(topicName, new Message<Null, string> { Value = value });
Console.WriteLine($"[{id}] sent record (key={deliveryReport.Key} value={deliveryReport.Value}) meta (partition={deliveryReport.TopicPartition.Partition}, offset={deliveryReport.TopicPartitionOffset.Offset}, time={deliveryReport.Timestamp.UnixTimestampMs})");
Thread.Sleep(waitMsInBetween);
}
}
}
```
Before starting the producer, in an additional terminal, let's use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-dotnet-topic`.
```bash
kcat -b kafka-1 -t test-dotnet-topic -f 'Part-%p => %k:%s\n' -q
```
Now run it using the `dotnet run` command. It will generate 1000 messages, waiting 10ms in-between sending each message and use 0 for the `id`.
```bash
dotnet run -p ./producer/producer.csproj 1000 10 0
```
The log will show each messages metadata after it has been sent and at the end you can see that it took **20 seconds** to send the 1000 records
```bash
[0] sent record (key= value=[0:0] Hello Kafka 04/03/2022 12:33:21 +02:00) meta (partition=[2], offset=652, time=1648982001348)

[0] sent record (key= value=[12:0] Hello Kafka 04/03/2022 12:33:22 +02:00) meta (partition=[0], offset=1479, time=1648982002457)

...
Producing all records took : 20589 ms = (20 sec)
```
On the console consumer window, we can see in the output that the data is distributed over all 8 partitions using the round robin partition strategy. This is caused by the key being `Null`.
```bash
Part-6 => :[0:0] Hello Kafka 04/03/2022 13:07:53 +02:00
Part-2 => :[1:0] Hello Kafka 04/03/2022 13:07:54 +02:00
Part-4 => :[2:0] Hello Kafka 04/03/2022 13:07:54 +02:00
Part-7 => :[3:0] Hello Kafka 04/03/2022 13:07:54 +02:00
Part-6 => :[4:0] Hello Kafka 04/03/2022 13:07:54 +02:00

Part-3 => :[12:0] Hello Kafka 04/03/2022 13:07:54 +02:00
Part-7 => :[13:0] Hello Kafka 04/03/2022 13:07:54 +02:00
Part-3 => :[14:0] Hello Kafka 04/03/2022 13:07:54 +02:00
Part-5 => :[15:0] Hello Kafka 04/03/2022 13:07:54 +02:00
Part-5 => :[16:0] Hello Kafka 04/03/2022 13:07:54 +02:00
...
```
### Produce Synchronously using the `id` field as the key
Instead of producing a `Null` key as before, let's use the `id` argument as the key. You can either change the current method or copy/paste it to a new one as we do here:
```csharp
static async Task runProducerSyncWithKey(int totalMessages, int waitMsInBetween, int id)
{
var config = new ProducerConfig { BootstrapServers = brokerList };
// Create the Kafka Producer
using (var producer = new ProducerBuilder<int, string>(config).Build())
{
for (int index = 0; index < totalMessages; index++)
{
long time = DateTimeOffset.Now.ToUnixTimeMilliseconds();
// Construct the message value
string value = "[" + index + ":" + id + "] Hello Kafka " + DateTimeOffset.Now;
// send the message to Kafka
var deliveryReport = await producer.ProduceAsync(topicName, new Message<int, string> { Key = id, Value = value });
Console.WriteLine($"[{id}] sent record (key={deliveryReport.Key} value={deliveryReport.Value}) meta (partition={deliveryReport.TopicPartition.Partition}, offset={deliveryReport.TopicPartitionOffset.Offset}, time={deliveryReport.Timestamp.UnixTimestampMs})");
Thread.Sleep(waitMsInBetween);
}
}
}
```
Change the `Main()` method to run the new method
```csharp
...
{
if (args.Length == 0) {
runProducerSyncWithKey(100, 10, 0);
} else {
runProducerSyncWithKey(int.Parse(args[0]), int.Parse(args[1]), int.Parse(args[2]));
}
}
...
```
Again use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-dotnet-topic` before starting the producer.
```bash
kcat -b kafka-1 -t test-dotnet-topic -f 'Part-%p => %k:%s\n' -q
```
Now run the producer and check the output in kafka console consumer
```bash
dotnet run --project ./producer/producer.csproj 1000 10 0
```
you can see from the log that all the message have been sent to the same partitions
```bash
[0] sent record (key=0 value=[0:0] Hello Kafka 04/03/2022 12:36:15 +02:00) meta (partition=[4], offset=1587, time=1648982175963)
[0] sent record (key=0 value=[1:0] Hello Kafka 04/03/2022 12:36:16 +02:00) meta (partition=[4], offset=1588, time=1648982176961)
[0] sent record (key=0 value=[2:0] Hello Kafka 04/03/2022 12:36:16 +02:00) meta (partition=[4], offset=1589, time=1648982176971)
[0] sent record (key=0 value=[3:0] Hello Kafka 04/03/2022 12:36:16 +02:00) meta (partition=[4], offset=1590, time=1648982176981)
[0] sent record (key=0 value=[4:0] Hello Kafka 04/03/2022 12:36:16 +02:00) meta (partition=[4], offset=1591, time=1648982176991)
[0] sent record (key=0 value=[5:0] Hello Kafka 04/03/2022 12:36:17 +02:00) meta (partition=[4], offset=1592, time=1648982177001)
[0] sent record (key=0 value=[6:0] Hello Kafka 04/03/2022 12:36:17 +02:00) meta (partition=[4], offset=1593, time=1648982177012)

[0] sent record (key=0 value=[10:0] Hello Kafka 04/03/2022 12:36:17 +02:00) meta (partition=[4], offset=1597, time=1648982177052)
...
Producing all records took : 20643 ms = (20 sec)
```
On the console consumer, we can see in the output that the data is distributed over all 8 partitions using the round robin partition strategy. This is caused by the key being `Null`.
```bash
Part-4 => :[0:0] Hello Kafka 04/03/2022 12:36:15 +02:00
Part-4 => :[1:0] Hello Kafka 04/03/2022 12:36:16 +02:00

### Produce Asynchronously
To produce asynchronously, we can either use the `ProduceAsync` or the `Produce` method. We first show the `ProduceAsync` method and basically adapt the version used for the synchronous produce.
To asynchronously handle delivery result notifications, we can use `Task.ContinueWith` as shown by the `runProducerASync` method:
```csharp
static void runProducerASync(int totalMessages, int waitMsInBetween, int id)
{
var config = new ProducerConfig { BootstrapServers = brokerList };
// Create the Kafka Producer
using (var producer = new ProducerBuilder<Null, string>(config).Build())
{
for (int index = 0; index < totalMessages; index++)
{
long time = DateTimeOffset.Now.ToUnixTimeMilliseconds();
// Construct the message value
string value = "[" + index + ":" + id + "] Hello Kafka " + DateTimeOffset.Now;
// send the message to Kafka
var deliveryReport = producer.ProduceAsync(topicName, new Message<Null, string> { Value = value });
deliveryReport.ContinueWith(task =>
{
if (task.IsFaulted)
{
}
else
{
Console.WriteLine($"[{id}] sent record (key={task.Result.Key} value={task.Result.Value}) meta (partition={task.Result.TopicPartition.Partition}, offset={task.Result.TopicPartitionOffset.Offset}, time={task.Result.Timestamp.UnixTimestampMs})");
}
});
Thread.Sleep(waitMsInBetween);
}
producer.Flush(TimeSpan.FromSeconds(10));
}
}
```
Change the `Main()` method to use the new method
```csharp
...
{
if (args.Length == 0) {
runProducerASync(100, 10, 0);
} else {
runProducerASync(int.Parse(args[0]), int.Parse(args[1]), int.Parse(args[2]));
}
}
...
```
Once again use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-dotnet-topic` before starting the producer.
```bash
kcat -b kafka-1 -t test-dotnet-topic -f 'Part-%p => %k:%s\n' -q
```
Now run the producer and check the output in kafka console consumer.
```bash
dotnet run --project ./producer/producer.csproj 1000 10 0
```
We can see that asynchronously the processing went down to **12 seconds** compared to the **20 seconds** it took for the synchronous way. The speed up is only because we no longer wait for the metadata before sending the next message.

Producing all records took : 12978 ms = (12 sec)
```
**Note:** We will later see (after seeing how to consume) how we can increase the producer rate by enabling batching on the producer side.
As we said before, there is a second was to produce asynchronously using the `Produce` method, which takes a delivery handler delegate as a parameter. Let's add it as another method called `runProducerAsync2`
```csharp
static void runProducerASync2(int totalMessages, int waitMsInBetween, int id)
{
var config = new ProducerConfig { BootstrapServers = brokerList };
// Create the Kafka Producer
using (var producer = new ProducerBuilder<Null, string>(config).Build())
{
for (int index = 0; index < totalMessages; index++)
{
long time = DateTimeOffset.Now.ToUnixTimeMilliseconds();
// Construct the message value
string value = "[" + index + ":" + id + "] Hello Kafka " + DateTimeOffset.Now;
try
{
// send the message to Kafka
producer.Produce(topicName, new Message<Null, string> { Value = value },
(deliveryReport) =>
{
if (deliveryReport.Error.Code != ErrorCode.NoError)
{
Console.WriteLine($"Failed to deliver message: {deliveryReport.Error.Reason}");
}
else
{
Console.WriteLine($"[{id}] sent record (key={deliveryReport.Key} value={deliveryReport.Value}) meta (partition={deliveryReport.TopicPartition.Partition}, offset={deliveryReport.TopicPartitionOffset.Offset}, time={deliveryReport.Timestamp.UnixTimestampMs})");
}
});
}
catch (ProduceException<Null, string> e)
{
Console.WriteLine($"failed to deliver message: {e.Message} [{e.Error.Code}]");
}
Thread.Sleep(waitMsInBetween);
}
producer.Flush(TimeSpan.FromSeconds(10));
}
}
```
Change the `Main()` method to use the new method `runProducerAsync2`
```csharp
...
{
if (args.Length == 0) {
runProducerASync2(100, 10, 0);
} else {
runProducerASync2(int.Parse(args[0]), int.Parse(args[1]), int.Parse(args[2]));
}
}
...
```
Once again use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-dotnet-topic` before starting the producer.
```bash
kcat -b kafka-1 -t test-dotnet-topic -f 'Part-%p => %k:%s\n' -q
```
Now run the producer and check the output in kafka console consumer.
```bash
dotnet run --project ./producer/producer.csproj 1000 10 0
```
We can see that asynchronously the processing took the same **12 seconds** as with the `AsyncProduce` method.
```bash

Producing all records took : 12959 ms = (12 sec)
```
As noted before, we will later see how we can increase the throughput by adding batching. But first let's see how to write a consumer in C#.
## Create a Kafka Consumer
Now let's create the consumer, which consumes the messages from the Kafka topic.
First let's create a new project
```bash
dotnet new console -o consumer
```
Again add a reference to library from the .NET Core project, by executing the following command from within the `kafka-dotnet-workspace` folder.
```bash
dotnet add consumer package Confluent.Kafka
```
Now let's add the code for consuming the messages from the Kafka topic. Navigate to the `Program.cs` C# class in the consumer project and rename it to `KafkaConsumer.cs` and then open it in the editor.
Add the following directives on the top with the class and the following two constants for the Broker List, the Topic name and the consumer group to use
```csharp
using System.Threading;
using Confluent.Kafka;
class KafkaConsumer
{
const string brokerList = "dataplatform:9092,dataplatform:9093";
const string topicName = "test-dotnet-topic";
const string groupId = "KafkaConsumerAuto";
}
```
Add the following main method to the class:
```csharp
static void Main(string[] args)
{
if (args.Length == 0)
{
runConsumerAuto(10);
}
else
{
runConsumerAuto(int.Parse(args[0]));
}
}
```
Add the following additional method for implementing the Kafka consumer. First we implement a consumer with using Auto Commit mode.
```csharp
static void runConsumerAuto(int waitMsInBetween)
{
var config = new ConsumerConfig
{
BootstrapServers = brokerList,
GroupId = groupId,
AutoOffsetReset = AutoOffsetReset.Earliest,
EnableAutoCommit = true,
AutoCommitIntervalMs = 2000
};
bool cancelled = false;
using (var consumer = new ConsumerBuilder<Ignore, string>(config).Build())
{
consumer.Subscribe(topicName);
var cancelToken = new CancellationTokenSource();
while (!cancelled)
{
var consumeResult = consumer.Consume(cancelToken.Token);
// handle message
Console.WriteLine($"Consumer Record:(Key: {consumeResult.Message.Key}, Value: {consumeResult.Message.Value} Partition: {consumeResult.TopicPartition.Partition} Offset: {consumeResult.TopicPartitionOffset.Offset}");
Thread.Sleep(waitMsInBetween);
}
consumer.Close();
}
}
```
Now run it using the `dotnet run` command. It will print the consumed messages to the console.
```
dotnet run -p ./consumer/consumer.csproj
```
Rerun one of the producers, if you need additional messages.
You can check the commits by consuming from the internal `__consumer_offsets` topic. For that we have to specify a special formatter for deserialising the commit messages.
```
docker exec -ti kafka-1 kafka-console-consumer --formatter "kafka.coordinator.group.GroupMetadataManager\$OffsetsMessageFormatter" --bootstrap-server kafka-1:19092 --topic __consumer_offsets
```
In the output of the consumer you can see that a commit message is issued every **5 seconds**, due to the `AutoCommitIntervalMs = 5000` setting.
```bash
[KafkaConsumerAuto,test-dotnet-topic,1]::OffsetAndMetadata(offset=9253, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988661678, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,2]::OffsetAndMetadata(offset=6160, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988661678, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,3]::OffsetAndMetadata(offset=3731, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988661678, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,7]::OffsetAndMetadata(offset=4185, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988666697, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,0]::OffsetAndMetadata(offset=4834, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988666697, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,4]::OffsetAndMetadata(offset=5563, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988666697, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,3]::OffsetAndMetadata(offset=3748, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988666697, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,5]::OffsetAndMetadata(offset=2479, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988666697, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,6]::OffsetAndMetadata(offset=3455, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988671713, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,7]::OffsetAndMetadata(offset=4279, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648988671713, expireTimestamp=None)
```
Now let's switch from auto commit mode to manual commit.
### Kafka Consumer with Manual Commit
Create a new method `runConsumerManual` which uses the manual method to commit offsets.
We use a hardcoded value (`50`) for the commit block size, so that a commit will happen every 50 messages.
```csharp
static void runConsumerManual(int waitMsInBetween)
{
var config = new ConsumerConfig
{
BootstrapServers = brokerList,
GroupId = groupId,
EnableAutoCommit = false
};
bool cancelled = false;
int noRecordsCount = 0;
using (var consumer = new ConsumerBuilder<Ignore, string>(config).Build())
{
consumer.Subscribe(topicName);
var cancelToken = new CancellationTokenSource();
ConsumeResult<Ignore, string> consumeResult = null;
while (!cancelled)
{
consumeResult = consumer.Consume(cancelToken.Token);
noRecordsCount++;
// handle message
Console.WriteLine($"Consumer Record:(Key: {consumeResult.Message.Key}, Value: {consumeResult.Message.Value} Partition: {consumeResult.TopicPartition.Partition} Offset: {consumeResult.TopicPartitionOffset.Offset}");
Thread.Sleep(waitMsInBetween);
if (consumeResult.Offset % 50 == 0)
{
consumer.Commit(consumeResult);
}
}
// commit the rest
consumer.Commit(consumeResult);
consumer.Close();
}
}
```
Change the `Main` method to use the new `runConsumerManual` method.
```csharp
...
{
if (args.Length == 0)
{
runConsumerManual(10);
}
else
{
runConsumerManual(int.Parse(args[0]));
}
}
```
Run the program again (produce some new messages before, if you have consumed all messages in the previous run)
```bash
dotnet run -p ./consumer/consumer.csproj
```
and check the commits by consuming again from the internal `__consumer_offsets` topic.
```
docker exec -ti kafka-1 kafka-console-consumer --formatter "kafka.coordinator.group.GroupMetadataManager\$OffsetsMessageFormatter" --bootstrap-server kafka-1:19092 --topic __consumer_offsets
```
We can see that we clearly commit every 50 records
```bash
[KafkaConsumerAuto,test-dotnet-topic,1]::OffsetAndMetadata(offset=9301, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989071728, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,1]::OffsetAndMetadata(offset=9351, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989072383, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,1]::OffsetAndMetadata(offset=9401, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989073024, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,0]::OffsetAndMetadata(offset=4901, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989073987, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,0]::OffsetAndMetadata(offset=4951, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989074610, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,5]::OffsetAndMetadata(offset=2551, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989075843, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,5]::OffsetAndMetadata(offset=2601, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989076468, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,4]::OffsetAndMetadata(offset=5601, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989077335, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,4]::OffsetAndMetadata(offset=5651, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989077976, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,4]::OffsetAndMetadata(offset=5701, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989078622, expireTimestamp=None)
[KafkaConsumerAuto,test-dotnet-topic,3]::OffsetAndMetadata(offset=3801, leaderEpoch=Optional.empty, metadata=, commitTimestamp=1648989079600, expireTimestamp=None)
```
## Using Batching with ProducerAsync
Let's see how we can add the throughput by enabling batching on producer side.
For that we have to add either one or both of `LingerMs` and `BatchSize` to the `ProducerConfig`.
Before we add it, let's see how fast we can produce by running the producer with 5x more records (`5000`) and no wait in between each produce (`waitMsInBetween = 0`).
First using the `runProducerSync` method, producing the 5000 records with no delay takes 43 seconds:
```bash
Producing all records took : 43324 ms = (43 sec)
```
Now lets run the `runProducerASync` method, first with `LingerMs` set to `0`, no batching.
```bash
var config = new ProducerConfig { BootstrapServers = brokerList, LingerMs = 0 };
```
we can see that in this case, producing is down to 1 second:
```bash
Producing all records took : 1068 ms = (1 sec)
```
Lets increase `linger.ms` to 1 second:
```bash
var config = new ProducerConfig { BootstrapServers = brokerList, LingerMs = 1000 };
```
Running it reveals the better throughput with batching, we are down to **377ms** for producing the 5000 records.
```bash
Producing all records took : 377 ms = (0 sec)
```
## Try running Producer and Consumer together
To see how scalability on the consumer side works, let's start multiple consumers consuming the records sent by the producer. Run the various consumers from a terminal window each and the producer from another one.
You should see that the consumers get the records that the producer sent.
### Three Consumers in same group and one Producer sending 25 messages
Make sure that you switch back to the first version of the producer where no key is produced (method `runProducer`). Start the consumer 3 times by executing the following command in 3 different terminal windows.
```bash
dotnet run -p ./consumer/consumer.csproj
```
and then start one of the producer which distributes the messages over all partitions:
```bash
dotnet run -p ./producer/producer.csproj 25 0 0
```
#### Producer Output
you see the 25 records being created to different partitions.
```bash

### Three Consumers in same group and one Producer sending 10 messages using key
Switch the producer to use the method with key (`runProducerSyncWithKey`). Start the consumer 3 times by executing the following command in 3 different terminal windows.
```bash
dotnet run -p ./consumer/consumer.csproj
```
and then start the producer (using 10 for the ID)
```
dotnet run -p ./producer/producer.csproj 25 0 10
```
#### Producer Output

# Support StreamSets Data Collector Activation
This recipe will show how to support activation of StreamSets Data Collector in persistent and replayable way.
The problem with the activation of StreamSets is, that an activation code is given for a given `SDC ID` (a.k.a product id). If you restart the StreamSets Data Collector container, everything is fine, but if you stop, remove and recrate the container, a new `SDC ID` is generated and you have to re-activate StreamSets.
This recipe shows, how the `SDC ID` can be fixed to a value, so that recreating a container won't change it.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services STREAMSETS -s trivadis/platys-modern-data-platform -w 1.13.0
```
Edit the `config.yml` and add the following configuration settings.
```
STREAMSETS_http_authentication: 'form'
STREAMSETS_sdc_id: ''
```
Now generate data platform
```
platys gen
```
and then start the platform:
```
docker-compose up -d
```
## Activate StreamSets
Navigate to <http://172.26.121.207:18630> and login with **user** set to `admin` and **password** set to `<PASSWORD>`.
Click on **Enter a Code** and on the **Activation** page click on **Back**. The **Register** page should be shown.
Fill out all the fields and click on **Agree to Terms and Register**.
Check your email inbox, after a short while you should get and email with an Activation Code.
Copy the section within `--------SDC ACTIVATION CODE--------` (example below has been tampered, so it is no longer usable)
```
--------SDC ACTIVATION CODE--------
xcv<KEY>
--------SDC ACTIVATION CODE--------
```
and paste it into the **Activation Code** field on the **Activation** screen. Take note of the product id shown above the **Activation Code** (will use that in the next section).
Make sure that you replace both `SDC ACTIVATION CODE` with `SDC ACTIVATION KEY` and click on **Activate**. The window should close and on another pop-up dialog you should be able to click on **Reload** to finish activation of StreamSets.
## Fix SDC ID to the value used for the Activation
Now we will enter the `SDC ID` (product id) into the `config.yml` so that it "surrive" a container stop and remove.
To get the right value, you can check the log or use the value from the Activation page before.
To retrieve it from the log, perform
```
docker-compose logs -f streamsets-1 | grep "SDC ID"
```
you should see an output similar to the one below
```
docker@ubuntu:~/platys-cookbook$ docker-compose logs -f streamsets-1 | grep "SDC ID"
streamsets-1 | 2021-07-06 19:49:59,955 [user:] [pipeline:] [runner:] [thread:main] [stage:]
INFO Main - SDC ID : 577164ca-de93-11eb-818c-892d3b5f064a
```
Copy the SDC ID info `577164ca-de93-11eb-818c-892d3b5f064a` and paste it into the `STREAMSETS_sdc_id` of the `config.yml`.
```
STREAMSETS_sdc_id: '577164ca-de93-11eb-818c-892d3b5f064a'
```
Regenerate the stack
```
platys gen
```
restart docker-compose
```
docker-compose up -d
```
and the follwing output should be shown on the console
```
Recreating streamsets-1 ...
wetty is up-to-date
Recreating streamsets-1 ... done
Starting markdown-renderer ... done
```
As you can see, the `streamsets-1` container will be re-created, using the same `SDC ID` as before.
When reloading the StreamSets UI, you will have to re-activate, but you can now use the exact same Activation Code as before.
<file_sep># OpenTelemetry Collector
The OpenTelemetry Collector offers a vendor-agnostic implementation on how to receive, process and export telemetry data. In addition, it removes the need to run, operate and maintain multiple agents/collectors in order to support open-source telemetry data formats (e.g. Jaeger, Prometheus, etc.) sending to multiple open-source or commercial back-ends.
**[Website](https://opentelemetry.io/)** | **[Documentation](https://opentelemetry.io/docs/collector/)** | **[GitHub](https://github.com/open-telemetry/opentelemetry-collector)**
## How to enable?
```
platys init --enable-services OTEL_COLLECTOR
platys gen
```
## How to use it?
OLTP receiver is listening on Port `4317` and recives data via gRPC or HTTP using [OTLP](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/protocol/otlp) format.
```
"-javaagent:/tmp/opentelemetry-javaagent.jar -Dotel.exporter.otlp.endpoint=otel-collector:4317"

<file_sep># DataHub
Data ecosystems are diverse — too diverse. DataHub's extensible metadata platform enables data discovery, data observability and federated governance that helps you tame this complexity.
**[Website](https://datahubproject.io/)** | **[Documentation](https://datahubproject.io/docs/)** | **[GitHub](https://github.com/linkedin/datahub)**
## How to enable?
```
platys init --enable-services DATAHUB
platys gen
```
## How to use it?
Navigate to <http://dataplatform:28144> and log in with user `datahub` and password `<PASSWORD>`.
### How to change the password of the `datahub`user?
Create a file `user.props` in `./security/datahub` and add a line with `datahub:<password>`
```
datahub:abc123!
```
Enable the mapping of `user.props` into the docker container
```yaml
DATAHUB_map_user_props: true
```
and re-run `platys gen`.

# Working with Tipboard and Kafka
This recipe will show how to use Tipboard with Kafka to stream data to the dashboard.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services TIPBOARD,KAFKA,KSQLDB,AKHQ,KCAT -n cookbook-platform -s trivadis/platys-modern-data-platform -w 1.14.0
```
edit the `config.yml` and add the connector to the following property
```
TIPBOARD_volume_map_dashboards: true
TIPBOARD_redis_password: '<PASSWORD>!'
```
start the platform
```
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Create the Tipboard Layout
Create a file `layout_config.yaml` in the `scripts/tipboard` folder
```
details:
page_title: Sample Dashboard

## Create a Kafka topic and simulate values
Create a Kafka topic
```bash
docker exec -ti kafka-1 kafka-topics --bootstrap-server kafka-1:19092 --create --topic sensor-readings --replication-factor 3 --partitions 3
```
Create the simulator definition
```bash
mkdir simulator-conf
nano simulator-conf/devices-def.json
```
```json
[
{
"type":"simple",
"uuid":"",
"topic":"sensor-readings",
"sampling":{"type":"fixed", "interval":1000},
"copy":10,
"sensors":[
{"type":"dev.timestamp", "name":"ts", "format":"yyyy-MM-dd'T'HH:mm:ss.SSSZ"},
{"type":"dev.uuid", "name":"uuid"},
{"type":"double_walk", "name":"temp", "min":-15, "max":3},

{"type":"string", "name":"level", "random": ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o"]}
]
}
]
```
Run the simulator
```bash
docker run --network cookbook-platform -v $PWD/simulator-conf/devices-def.json:/conf/devices-def.json trivadis/iot-simulator -dt KAFKA -u kafka-1:19092 -t iot/ -cf /conf/devices-def.json

# Using Dev Simulator Origin to simulate streaming data
This recipe shows how to use the StreamSets Dev Simulator Origin to simulate event data taken from one or more CSV files. Each CSV row must contain a timestamp which tells the simulator when to publish the data.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services STREAMSETS,KAFKA,KAFKA_AKHQ,KCAT -s trivadis/platys-modern-data-platform -w 1.16.0
```
Edit the `config.yml` and add the following configuration settings.
```
STREAMSETS_stage_libs: 'streamsets-datacollector-apache-kafka_2_7-lib'
```
Now generate data platform and download the Streamsets Custom origin to the right folder.
```
platys gen
```
Download and unpack the Dev Simulator custom origin
```
cd plugins/streamsets/user-libs
wget https://github.com/TrivadisPF/streamsets-dev-simulator/releases/download/0.8.2/dev-simulator-0.8.2.tar.gz
tar -xvzf dev-simulator-0.8.2.tar.gz
rm dev-simulator-0.8.2.tar.gz
cd ../../..
```
Download the data and unpack into `data-transfer` folder
```
cd data-transfer
wget https://github.com/TrivadisPF/platys-modern-data-platform/raw/master/cookbooks/recipes/using-dev-simulator-origin/cookbook-data.tar.gz
tar -xvzf cookbook-data.tar.gz
rm cookbook-data.tar.gz
```
Start the platform:
```
docker-compose up -d
```
You can find the StreamSets pipelines of this cookbook recipe in the folder `streamsets`.
All samples write the data to a Kafka topic called `streamsets-simulator`. You need to create that first, either through the graphical UI **AKHQ** or using the command line:
```bash
docker exec -ti kafka-1 kafka-topics --create --bootstrap-server kafka-1:19092 --topic streamsets-simulator
```
To consume from it, use `kcat` as shown here:
```bash
docker exec -ti kcat kcat -b kafka-1:19092 -t streamsets-simulator -q -o end
```
The data written to Kafka also include the `EventTimestamp` field as a string as well as the start timestamp formatted as string.
## Using Relative from Anchor Time
When using the **Relative from Anchor Time** mode, the anchor is representing the start of the simulation and all the timestamp of the rows of the input file(s) are relative to that anchor. The following diagram represents the data of the input files shown below.
### File without header row (01)
The following examples shows the simulator used for a file without a header row and with the timestamp resolution of second.
`relative-anchor-without-header.csv`
```
1,10,1
5,10,2
10,10,3
15,10,4
20,10,5
```
Streamsets Pipeline: `01 - RelativeAnchorTimeWithoutHeader`
Dev Simulator Properties (only the ones which have to change from the defaults):
* **Files**
* **Files Directory:** `/data-transfer/cookbook-data`
* **File Name Pattern:** `relative-anchor-without-header.csv`
* **Different Record Types?:** `false`
* **Event Time**
* **Timestamp Mode:** `Relative from Anchor Timestamp`
* **Timestamp Field:** `/0`
* **Relative Time Resolution:** `seconds`
* **Anchor Time is Now?:** `true`
* **Data Format**
* **Header Line:** `No Header Line`
The output on `kcat` should show these events
```bash
{"0":"1","1":"10","2":"1","EventTimestamp":1669533859458,"EventTimestampString":"07:24:19","StartEventTimestampString":"07:24:18"}

* **Data Format**
* **Header Line:** `No Header Line`
The output on `kcat` should show these events
```bash
{"0":"1000","1":"10","2":"1","EventTimestamp":1669533981035,"EventTimestampString":"07:26:21","StartEventTimestampString":"07:26:20"}

## Using Absolute with Start Timestamp earlier than first Event
When using the **Absolute with Start Timestamp earlier than first Event** mode, a start timestamp is specified which is before for equal to the first timestamp in the data. The start timestamp specified is used as the start time for the simulation
The following diagram represents the data of the input files shown.
### File without header (14)
The following examples shows the simulator used for a file without a header row and with absolute timestamps.
`absolute-without-header.csv`

# Querying data in Postgresql from Trino (formerly PrestoSQL)
This tutorial will show how to query Postgresql table from Trino.
## Initialise a platform
First [initialise a platys-supported data platform](../../getting-started.md) with the following services enabled
```
platys init --enable-services TRINO,POSTGRESQL,ADMINER,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.11.0
```
add the follwing property to `config.yml`
```
TRINO_edition: 'oss'
```
Now set an environment variable to the home folder of the dataplatform and generate and then start the data platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Create Table in Postgresql
```
docker exec -ti postgresql psql -d demodb -U demo
```
```
CREATE SCHEMA flight_data;
DROP TABLE flight_data.airport_t;
CREATE TABLE flight_data.airport_t
(
iata character varying(50) NOT NULL,
airport character varying(50),
city character varying(50),
state character varying(50),
country character varying(50),
lat float,
long float,
CONSTRAINT airport_pk PRIMARY KEY (iata)
);
```
```
COPY flight_data.airport_t(iata,airport,city,state,country,lat,long)
FROM '/data-transfer/flight-data/airports.csv' DELIMITER ',' CSV HEADER;
```
```
SELECT * FROM flight_data.airport_t LIMIT 20;
```
## Query Table from Trino
Next let's query the data from Trino. Connect to the Trino CLI using
```
docker exec -it trino-cli trino --server trino-1:8080
```
Now on the Presto command prompt, switch to the right database.
```
use postgresql.flight_data;
```
Let's see that there is one table available:
```
show tables;
```
We can see the `airport_t` table we created in the Hive Metastore before
```
presto:default> show tables;
Table
---------------
airport_t
(1 row)
```
```
SELECT * FROM airport_t;
```
```
SELECT country, count(*)
FROM airport_t
GROUP BY country;
```
<file_sep>Contains the sys of prometheus node exporter service, if flag PROMETHEUS_volume_map_data is set to true.<file_sep># Custom UDF and ksqlDB
This recipe will show how to use a custom UDF with ksqlDB. We will see a "normal" UDF in action, which is a stateless function working on scalar value. Besides the UDFs, you can also create stateful aggregate functions (UDAFs) and table functions (UDTFs). Find more information on these 3 types of user-defined functions in the [ksqlDB documentation](https://docs.ksqldb.io/en/latest/concepts/functions/).
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started.md) with the following services enabled
```bash
platys init --enable-services KAFKA,KAFKA_KSQLDB -s trivadis/platys-modern-data-platform -w 1.9.1
```
Now set an environment variable to the home folder of the dataplatform and generate and then start the data platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Create the UDF
You can find the complete Java project in the subfolder [ksql-udf-string](./ksql-udf-string).
Add the following to the `~/.m2/settings.xml`:
```xml
<settings>
<profiles>
<profile>
<id>myprofile</id>
<repositories>
<!-- Confluent releases -->
<repository>
<id>confluent</id>
<url>https://packages.confluent.io/maven/</url>
</repository>
<!-- further repository entries here -->
</repositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>myprofile</activeProfile>
</activeProfiles>
</settings>
```
Run the following command to create a new Maven project:
```bash
mvn archetype:generate -X \
-DarchetypeGroupId=io.confluent.ksql \
-DarchetypeArtifactId=ksqldb-udf-quickstart \
-DarchetypeVersion=6.0.0
```
Fill out the arguments being prompted for.
Add the following dependency to the POM:
```xml
<dependencies>
<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-lang3 -->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-lang3</artifactId>
<version>3.11</version>
</dependency>
```
Create a Java package `com.trivadis.ksql.demo` and in it create the following Java class:
```java
package com.trivadis.ksql.demo;
import io.confluent.ksql.function.udf.Udf;
import io.confluent.ksql.function.udf.UdfDescription;
import io.confluent.ksql.function.udf.UdfParameter;
import org.apache.commons.lang3.StringUtils;
@UdfDescription(name = "del_whitespace", description = "Deletes all whitespaces from a String")
public class StringUDF {
@Udf(description = "Deletes all whitespaces from a String")
public String adjacentHash(@UdfParameter(value="string", description = "the string to apply the function on") String value) {
return StringUtils.deleteWhitespace(value);
}
}
```
Build the Java project using
```
mvn clean package
```
Inside the `target` folder, a jar named `ksql-udf-string-1.0-jar-with-dependencies.jar` should be created.
## Copy the JAR to the ksqlDB engine folder
When working with Platys, the `target/ksql-udf-string-1.0-jar-with-dependencies.jar` JAR file has to be copied into the folder `$DATAPLATFORM_HOME/plugins/ksql`, from where it will be picked-up by the kqlDB engine.
Restart the ksqldb servers using
```
docker restart ksqldb-server-1
docker restart ksqldb-server-2
```
If you have more than 2 servers running, do it for the other ones as well.
## Test the UDF
Now let's see our UDF in action. For that let's connect to ksqlDB CLI
```bash
docker exec -it ksqldb-cli ksql http://ksqldb-server-1:8088
```
And show all functions
```
show functions;
```
Besides the built-in functions, our new UDF called `del_whitespace` should show up as well.
Let's create a new Stream backed by a topic, just for doing a `SELECT ...` to test the UDF
```
CREATE STREAM test_s (v1 VARCHAR)
WITH (kafka_topic='test',
value_format='JSON',
partitions=8,
replicas=3);
```
Let's call the UDF inside a `SELECT ... EMIT CHANGES`
```
SELECT del_whitespace(v1)
FROM test_s
EMIT CHANGES;
```
To see it working, we have to publish some data into the topic. The simplest way to do that is using an `INSERT INTO ...` from an other ksqlDB CLI.
```
INSERT INTO test_s VALUES ('<NAME>');
```
You should see the result in the previous ksqlDB CLI
```
ksql> select del_whitespace(v1) from test_s emit changes;

# NiFi ExecuteScript Processor with Python
This recipe will show how to use NiFi with Python.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```bash
export DATAPLATFORM_HOME=${PWD}
platys init --enable-services NIFI -s trivadis/platys-modern-data-platform -w 1.16.0
```
Before we can generate the platform, we need to extend the `config.yml`:
```
NIFI_python_enabled: true
NIFI_python_provide_requirements_file: true
NIFI_python_version: 3.10
```
We set enable the python environment (will switch to a custom Docker image extending the official NiFi image with python) and specify to provide additional Python modules with a `requirements.txt` file.
Save the file and generate and start the data platform.
```bash
platys gen
```
## Create the `requirements.txt` file
The `requirements.txt` file has to be created in `./custom-conf/nifi` folder of the platform.
Edit the file
```bash
nano ./custom-conf/nifi/requirments.txt`
```
and add the following module
```bash
XXXX
```
Now start the platform
```bash
docker-compose up -d
```
and once it is running navigate to the NiFi UI: <https://dataplatform:18080/nifi>.<file_sep># IoT Vehicle Tracking Workshop
In this workshop we will be ingesting data not directly into Kafka but rather through MQTT first. We will be using a fictitious Trucking company with a fleet of trucks constantly providing some data about the moving vehicles.
The following diagram shows the setup of the data flow we will be implementing.
We will show the implementation step-by-step. For the streaming analytics step we will see different solutions:
* [IoT Data Ingestion through MQTT into Kafka](../13a-iot-data-ingestion-over-mqtt)
* Stream Analytics
* [Stream Analytics using ksqlDB](../13b-stream-analytics-using-ksql)
* [Stream Analytcis with Java using Kafka Streams](../13c-stream-analytics-using-java-kstreams)

The environment for this course is completely based on docker containers.
In order to simplify the provisioning, a single docker-compose configuration is used. All the necessary software will be provisioned using Docker.
For Kafka we will be using the Docker images provided by Confluent and available under the following GitHub project: <https://github.com/confluentinc/cp-docker-images>. In this project, there is an example folder with a few different docker compose configuration for various Confluent Platform configurations.
You have the following options to start the environment:
* [**Local Virtual Machine Environment**](./LocalVirtualMachine.md) - a Virtual Machine with Docker and Docker Compose pre-installed will be distributed at by the course infrastructure. You will need 50 GB free disk space.
* [**Local Docker Environment**](./LocalDocker.md) - you have a local Docker and Docker Compose setup in place which you want to use
* [**AWS Lightsail Environment**](./Lightsail.md) - AWS Lightsail is a service in Amazon Web Services (AWS) with which we can easily startup an environment and provide all the necessary bootstrapping as a script.
## Post Provisioning
These steps are necessary after the starting the docker environment.
### Add entry to local `/etc/hosts` File
To simplify working with the Data Platform and for the links below to work, add the following entry to your local `/etc/hosts` file.
```
192.168.127.12 dataplatform
```
Replace the IP address by the public IP address of the docker host.

Configure the VM to use at 12 GB of Memory.
Install the following software
* [Docker](https://docs.docker.com/engine/install/ubuntu/)
* [Docker Compose](https://docs.docker.com/compose/install/)
* [Platys](https://github.com/TrivadisPF/platys/blob/master/documentation/install.md) (optional)
## Prepare Environment
In the Virtual Machine, start a terminal window and execute the following commands.
First let's add the environment variables. Make sure to adapt the network interface (**ens33** according to your environment. You can retrieve the interface name by using **ipconfig** on windows or **ifconfig** on Mac/Linux.
```
# Prepare Environment Variables
export PUBLIC_IP=$(curl ipinfo.io/ip)
export DOCKER_HOST_IP=$(ip addr show ens33 | grep "inet\b" | awk '{print $2}' | cut -d/ -f1)
```
Now for Elasticsearch to run properly, we have to increase the `vm.max_map_count` parameter like shown below.
```
# needed for elasticsearch
sudo sysctl -w vm.max_map_count=262144
```
Now let's checkout the NoSQL Workshop project from GitHub:
```
# Get the project
cd /home/bigdata
git clone https://github.com/gschmutz/kafka-workshop.git
cd kafka-workshop/01-environment/docker
```
## Start Environment
And finally let's start the environment:
```
# Make sure that the environment is not running
docker-compose down
# Startup Environment
docker-compose up -d
```
The environment should start immediately, as all the necessary images should already be available in the local docker image registry.
The output should be similar to the one below.
Your instance is now ready to use. Complete the post installation steps documented the [here](README.md).
## Stop environment
To stop the environment, execute the following command:
```
docker-compose stop
```
after that it can be re-started using `docker-compose start`.
To stop and remove all running container, execute the following command:
```
docker-compose down
```

# Schedule and Run Simple Python Application with Airflow
This recipe will show how to use the [Apache Airflow](https://airflow.apache.org/) job orchestration engine with the [Bash Operator](https://airflow.apache.org/docs/apache-airflow/stable/_api/airflow/operators/bash/index.html#airflow.operators.bash.BashOperator) and [Python Operator](https://airflow.apache.org/docs/apache-airflow/stable/howto/operator/python.html).
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```bash
platys init --enable-services AIRFLOW -s trivadis/platys-modern-data-platform -w 1.16.0
```
add to `config.yml`
```yaml
AIRFLOW_executor: celery
AIRFLOW_dag_dir_list_interval: 30
```
Now generate and start the platform
```bash
platys gen
docker-compose up -d
```
Check the log of `airflow` to be up and running by running `docker logs -f airflow`. Airflow is ready if you see the **Listing at:...** in the log
```

## Open Airflow Dashboard
Navigate to <http://dataplatform:28139> and login with user `airflow` and password `<PASSWORD>!`. You should see the empty Airflow dashboard.
## Create an Airflow DAG
Now let's create a first example DAG.
In the `./scripts/airflow/dags` create a new file with the following DAG logic (we start the DAG every 5 minutes with a start date of today minus 2 hours.
`example-python.py`
```python
from datetime import datetime, timedelta
from textwrap import dedent
from airflow import DAG
# Operators; we need this to operate!
from airflow.operators.bash import BashOperator

}
dag_args = dict(

schedule_interval=timedelta(minutes=5),
start_date=datetime.today() - timedelta(hours=2, minutes=0),
tags=['example-sj'],
)
def random_branch_path():
# 필요 라이브러리는 여기서 import
# https://airflow.apache.org/docs/apache-airflow/stable/best-practices.html#writing-a-dag 참고
from random import randint
return "cal_a_id" if randint(1, 2) == 1 else "cal_m_id"
def calc_add(x, y, **kwargs):
result = x + y
print("x + y : ", result)
kwargs['task_instance'].xcom_push(key='calc_result', value=result)
return "calc add"
def calc_mul(x, y, **kwargs):
result = x * y
print("x * y : ", result)
kwargs['task_instance'].xcom_push(key='calc_result', value=result)
return "calc mul"
def print_result(**kwargs):
r = kwargs["task_instance"].xcom_pull(key='calc_result')
print("message : ", r)
print("*"*100)
print(kwargs)
def end_seq():
print("end")
with DAG( **dag_args ) as dag:
start = BashOperator(
task_id='start',
bash_command='echo "start!"',
)
branch = BranchPythonOperator(
task_id='branch',
python_callable=random_branch_path,
)
calc_add = PythonOperator(
task_id='cal_a_id',
python_callable=calc_add,
op_kwargs={'x': 10, 'y':4}
)
calc_mul = PythonOperator(
task_id='cal_m_id',
python_callable=calc_mul,
op_kwargs={'x': 10, 'y':4}
)
msg = PythonOperator(
task_id='msg',
python_callable=print_result,
trigger_rule=TriggerRule.NONE_FAILED
)
complete_py = PythonOperator(
task_id='complete_py',
python_callable=end_seq,
trigger_rule=TriggerRule.NONE_FAILED
)
complete = BashOperator(
task_id='complete_bash',
depends_on_past=False,
bash_command='echo "complete~!"',
trigger_rule=TriggerRule.NONE_FAILED
)
start >> branch >> calc_add >> msg >> complete_py >> complete
start >> branch >> calc_mul >> msg >> complete
```
After > 30 seconds (the `AIRFLOW_dag_dir_list_interval` configured in `config.yml`), the Airflow dashboard should refresh and show the newly created DAG.
By default the DAG will be initially in paused mode. Click on the button to the left of the DAG to unpause it.
Jobs will be immediately started for the last 2 hours, with an interval of 5 minutes between them.
If you click on the job you can see the details of the job with a graphic of each run.

# Using Public Oracle XE Docker image
This recipe will show how to use a public docker image for Oracle XE. This is instead of the "normal" way of referring to a private repository for the Oracle database docker images, due to licensing requirements by Oracle.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```bash
platys init --enable-services ORACLE_XE -s trivadis/platys-modern-data-platform -w 1.16.0
```
We are using the following docker image [gvenzl/oracle-xe](https://hub.docker.com/r/gvenzl/oracle-xe).
Now generate and start the data platform.
```bash
platys gen
docker-compose up -d
```
## Connect to Oracle
First connect to the docker instance
```bash
docker exec -ti oracledb-xe bash
```
and run SQL Plus to connect as user `sys` to the PDB.
```bash
sqlplus sys/EAo4KsTfRR@oracledb-xe:1521/XEPDB1 as sysdba
```

<file_sep># Stream Analytics using Streamiz
Let's redo the simple message filtering process of the previous workshop, using the [Streamiz.Kafka.Net](https://lgouellec.github.io/kafka-streams-dotnet) instead of KSQL. Streamiz.Kafka.Net is a .NET stream processing library for Apache Kafka (TM).
## Create the project structure
First create the workspace folder, which will hold our projects and navigate into it.
```bash
mkdir kafka-dotnet-streamiz
cd kafka-dotnet-streamiz
```
Now let's create the processor project
```bash
dotnet new console -o processor
```
Now start Visual Code, on Linux if installed using the [following documentation](https://code.visualstudio.com/docs/setup/linux), then it can be started with `code`.
```bash
code .
```
## Create the processor
To reference the library from the .NET Core project, execute the following command from within the `kafka-dotnet-streamiz` folder.
```
dotnet add processor package Streamiz.Kafka.Net
```
## Create the necessary Kafka Topic
We will use the topic `dangerous_driving_kstreams` for the output stream in the Kafka Streams code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
Connect to the `broker-1` container
```bash
docker exec -ti broker-1 bash
```
and execute the necessary `kafka-topics` command.
```bash
kafka-topics --bootstrap-server kafka-1:19092,kafka-2:19093 --create --topic dangerous_driving_streamiz --partitions 8 --replication-factor 2
```
## Create a Streamiz Topology
Open `Program.cs` in the editor and add a `TruckPosition` class, which is handling the transformation from/to CSV and then add the Streamiz topology after.
```csharp
using Confluent.Kafka;
using Streamiz.Kafka.Net;
using Streamiz.Kafka.Net.SerDes;
using Streamiz.Kafka.Net.Stream;
using Streamiz.Kafka.Net.Table;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.Intrinsics;
using System.Threading;
using Microsoft.Extensions.Logging;
using Streamiz.Kafka.Net.Crosscutting;
using System.Threading.Tasks;
namespace processor
{
class TruckPosition
{
long timestamp;
int truckId;
int driverId;
int routeId;
String eventType;
Double latitude;
Double longitude;
String correlationId;
public static TruckPosition create(String csvRecord) {
TruckPosition truckPosition = new TruckPosition();
String[] values = csvRecord.Split(',');
truckPosition.timestamp = Convert.ToInt64(values[0]);
truckPosition.truckId = Convert.ToInt32(values[1]);
truckPosition.driverId = Convert.ToInt32(values[2]);
truckPosition.routeId = Convert.ToInt32(values[3]);
truckPosition.eventType = values[4];
truckPosition.latitude = Convert.ToDouble(values[5]);
truckPosition.longitude = Convert.ToDouble(values[6]);
truckPosition.correlationId = values[7];
return truckPosition;
}
public static Boolean filterNonNORMAL(TruckPosition value) {
Boolean result = false;
result = !value.eventType.Equals("Normal");
return result;
}
public String toCSV() {
return timestamp + "," + truckId + "," + driverId + "," + routeId + "," + eventType + "," + latitude + "," + longitude + "," + correlationId;
}
}
class Program
{
static async Task Main(string[] args)
{
var config = new StreamConfig<StringSerDes, StringSerDes>();
config.ApplicationId = "test-app";
config.BootstrapServers = "dataplatform:9092";
StreamBuilder builder = new StreamBuilder();
builder.Stream<string, string>("truck_position")
.MapValues(v => TruckPosition.create(v.Remove(0,6)))
.Filter((k,v) => TruckPosition.filterNonNORMAL(v))
.MapValues(v => v.toCSV())
.To("dangerous_driving_streamiz");
Topology t = builder.Build();
KafkaStream stream = new KafkaStream(t, config);
Console.CancelKeyPress += (o, e) =>
{
stream.Dispose();
};
await stream.StartAsync();
}
}
}
```
With this in place, we can run the Topology from the terminal.
```bash
dotnet run -p ./processor/processor.csproj
```
Now let's see that we actually produce data on that new topic by running a `kafka-console-consumer` or alternatively a `kafkacat`.
```bash
kcat -b kafka-1:19092 -t dangerous_driving_streamiz
```

```
### Initialise JanusGraph
When the container is started it will execute files with the extension `.groovy` that are found in `./init/janusgraph/` with the Gremlin Console. These scripts are only executed after the JanusGraph Server instance was started. So, they can connect to it and execute Gremlin traversals.
For example, to add a vertex to the graph, create a file `./init/janusgraph/add-vertex.groovy` with the following content
```groovy
g = traversal().withRemote('conf/remote-graph.properties')
g.addV('demigod').property('name', 'hercules').iterate()

This recipe will show how to query data from a Kakfa topic using Trino. It is an adapted version of the tutorial in the [Trino documentation](https://trino.io/docs/current/connector/kafka-tutorial.html).
## Initialise a platform
First [initialise a platys-supported data platform](../../getting-started) with the following services enabled
```bash
platys init --enable-services TRINO,KAFKA,SCHEMA_REGISTRY,KAFKA_AKHQ,KAFKACAT,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.13.0
```
add the follwing property to `config.yml`
```bash
KAFKA_auto_create_topics_enable: true
TRINO_edition: 'oss'
TRINO_kafka_table_names: 'tpch.customer,tpch.orders,tpch.lineitem,tpch.part,tpch.partsupp,tpch.supplier,tpch.nation,tpch.region'
```
Now generate and start the data platform.
```bash
platys gen
docker-compose up -d
```
## Create Data in Kafka
Download the tpch-kafka loader from Maven central
```bash
curl -o kafka-tpch https://repo1.maven.org/maven2/de/softwareforge/kafka_tpch_0811/1.0/kafka_tpch_0811-1.0.sh
```
```bash
chmod 755 kafka-tpch
```
Now run the kafka-tpch program to preload a number of topics with tpch data
```bash
./kafka-tpch load --brokers localhost:29092 --prefix tpch. --tpch-type tiny
```
## Query Customer Table from Trino
Next let's query the data from Trino. Connect to the Trino CLI using
```bash
docker exec -it trino-cli trino --server trino-1:8080 --catalog kafka --schema tpch
```
List the tables to verify that things are working
```sql
show tables;
```
Kafka data is unstructured, and it has no metadata to describe the format of the messages.
```sql
DESCRIBE customer;
```
Without further configuration, the Kafka connector can access the data, and map it in raw form. However there are no actual columns besides the built-in ones:
```sql
trino:tpch> describe customer
-> ;
Column | Type | Extra | Comment
-------------------+--------------------------------+-------+---------------------------------------------
_partition_id | bigint | | Partition Id
_partition_offset | bigint | | Offset for the message within the partition
_message_corrupt | boolean | | Message data is corrupt
_message | varchar | | Message text
_headers | map(varchar, array(varbinary)) | | Headers of the message as map
_message_length | bigint | | Total number of message bytes
_key_corrupt | boolean | | Key data is corrupt
_key | varchar | | Key text
_key_length | bigint | | Total number of key bytes
_timestamp | timestamp(3) | | Message timestamp
(10 rows)
```
```sql
SELECT * FROM customer;
```
```sql
trino:tpch> select * from customer;
_partition_id | _partition_offset | _message_corrupt | _message >
---------------+-------------------+------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------->
0 | 0 | false | {"rowNumber":1,"customerKey":1,"name":"Customer#000000001","address":"IVhzIApeRb ot,c,E","nationKey":15,"phone":"25-989-741-2988","accountBalance":711.56,"marketSegment":"BUILDING","comment":"to the even, >

```
The data from Kafka can be queried using Trino, but it is not yet in actual table shape. The raw data is available through the _message and _key columns, but it is not decoded into columns. As the sample data is in JSON format, the [JSON functions and operators](https://trino.io/docs/current/functions/json.html) built into Trino can be used to slice the data.
We can use the `json_extract_scalar` function to extract the values from the `_message` column:
```sql
SELECT sum(cast(json_extract_scalar(_message, '$.accountBalance') AS double)) FROM customer LIMIT 10;
```
### Add a topic description file
The Kafka connector supports topic description files to turn raw data into table format. These files are located in the `etc/kafka` folder in the Trino installation and must end with .json. It is recommended that the file name matches the table name, but this is not necessary.
Create a file `tpch.customer.json` in the folder `conf/trino/kafka` (this is the folder which is mapped to `etc/kafka` inside the container)
```json
{
"tableName": "customer",
"schemaName": "tpch",
"topicName": "tpch.customer",
"key": {
"dataFormat": "raw",
"fields": [
{
"name": "kafka_key",
"dataFormat": "LONG",
"type": "BIGINT",
"hidden": "false"
}
]
},
"message": {
"dataFormat": "json",
"fields": [
{
"name": "row_number",
"mapping": "rowNumber",
"type": "BIGINT"
},
{
"name": "customer_key",
"mapping": "customerKey",
"type": "BIGINT"
},
{
"name": "name",
"mapping": "name",
"type": "VARCHAR"
},
{
"name": "address",
"mapping": "address",
"type": "VARCHAR"
},
{
"name": "nation_key",
"mapping": "nationKey",
"type": "BIGINT"
},
{
"name": "phone",
"mapping": "phone",
"type": "VARCHAR"
},
{
"name": "account_balance",
"mapping": "accountBalance",
"type": "DOUBLE"
},
{
"name": "market_segment",
"mapping": "marketSegment",
"type": "VARCHAR"
},
{
"name": "comment",
"mapping": "comment",
"type": "VARCHAR"
}
]
}
}
```
Restart trino
```bash
docker restart trino-1
```
```bash
docker exec -it trino-cli trino --server trino-1:8080 --catalog kafka --schema tpch
```
Now for all the fields in the JSON of the message, columns are defined and the sum query from earlier can operate on the `account_balance` column directly:
```sql
DESCRIBE customer;
```
```sql
trino:tpch> describe customer
-> ;
Column | Type | Extra | Comment
-------------------+--------------------------------+-------+---------------------------------------------
kafka_key | bigint | |
row_number | bigint | |
customer_key | bigint | |
name | varchar | |
address | varchar | |
nation_key | bigint | |
phone | varchar | |
account_balance | double | |
market_segment | varchar | |
comment | varchar | |
_partition_id | bigint | | Partition Id
_partition_offset | bigint | | Offset for the message within the partition
_message_corrupt | boolean | | Message data is corrupt
_message | varchar | | Message text
_headers | map(varchar, array(varbinary)) | | Headers of the message as map
_message_length | bigint | | Total number of message bytes
_key_corrupt | boolean | | Key data is corrupt
_key | varchar | | Key text
_key_length | bigint | | Total number of key bytes
_timestamp | timestamp(3) | | Message timestamp
(20 rows)
```
```sql
SELECT * FROM customer LIMIT 5;
```
```sql
SELECT sum(account_balance) FROM customer LIMIT 10;
```
Now all the fields from the customer topic messages are available as Trino table columns.
<file_sep># Setup necessary environment variables
Now the Platform is ready to be started. Before doing that, you have to create some environment variables, depending on the services you use. In minimum you should create
* `DOCKER_HOST_IP` - the IP address of the network interface of the Docker Host
* `PUBLIC_IP` - the IP address of the public network interface of the Docker Host (different to `DOCKER_HOST_IP` if in a public cloud environment
## Linux or Mac
First let's get the network interface name
```
$ ip addr
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:0c:29:3a:82:45 brd ff:ff:ff:ff:ff:ff
altname enp2s1
```
and set it as a variable
```
export NETWORK_NAME=ens33
```
If the Docker host is running in the cloud (as a VM), where a specific public IP address is needed to reach it, perform this command
```bash
export PUBLIC_IP=$(curl ipinfo.io/ip)
```
otherwise this command
```bash
export PUBLIC_IP=$(ip addr show $NETWORK_NAME | grep "inet\b" | awk '{print $2}' | cut -d/ -f1)
```
Additionally set the `DOCKER_HOST_IP` to the IP address of the machine (make sure that `$NETWORK_NAME` has been set correctly)
```bash
export DOCKER_HOST_IP=$(ip addr show $NETWORK_NAME | grep "inet\b" | awk '{print $2}' | cut -d/ -f1)
```
Now persist these two environment variables, so that they are available after a logout.
You can set these environment variables persistently on the machine (`/etc/environment`) or user (`~/.pam_environment` or `~/.bash_profile`) level. The following script sets the `.bash_profile` in the user home.
```bash
# Prepare Environment Variables into .bash_profile file
printf "export PUBLIC_IP=$PUBLIC_IP\n" >> /home/$USER/.bash_profile
printf "export DOCKER_HOST_IP=$DOCKER_HOST_IP\n" >> /home/$USER/.bash_profile
printf "\n" >> /home/$USER/.bash_profile
sudo chown ${USER}:${USER} /home/$USER/.bash_profile
```
Another option is to use the `.env` file in the folder where the `docker-compose.yml` file is located. All environment variables set in there are used when the docker compose environment is started.
## Windows

# Spark with PostgreSQL
This recipe will show how to use a Spark cluster in the platform and connect it to a PostgreSQL relational database.
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services SPARK,POSTGRESQL,ZEPPELIN,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.15.0
```
Before we can generate the platform, we need to extend the `config.yml`. There are two options
**1. use the `SPARK_jars_packages` property to specify a maven coordinate**
add the following property to `config.yml`
```
SPARK_jars_packages: 'org.postgresql:postgresql:42.3.4'
```
**2. use the `SPARK_jars` property to point to jar provided in `./plugins/spark/jars`**
download the Jar file from the maven repository to `./plugins/spark/jars`
```bash
cd $DATAPLATFORM_HOME
cd ./plugins/spark/jars
wget https://repo1.maven.org/maven2/org/postgresql/postgresql/42.3.4/postgresql-42.3.4.jar -O postgresql-42.3.4.jar
```
now add the following property to `config.yml`
```
SPARK_jars: '/extra-jars/postgresql:42.3.4.jar'
```
Now set an environment variable to the home folder of the dataplatform and generate and then start the data platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Create Table in Postgresql
```bash
docker exec -ti postgresql psql -d demodb -U demo
```
```sql
CREATE SCHEMA flight_data;
DROP TABLE flight_data.airport_t;
CREATE TABLE flight_data.airport_t
(
iata character varying(50) NOT NULL,
airport character varying(50),
city character varying(50),
state character varying(50),
country character varying(50),
lat float,
long float,
CONSTRAINT airport_pk PRIMARY KEY (iata)
);
```
```sql
COPY flight_data.airport_t(iata,airport,city,state,country,lat,long)
FROM '/data-transfer/flight-data/airports.csv' DELIMITER ',' CSV HEADER;
```
## Work with data from PostgreSQL
Navigate to Zeppelin <http://dataplatform:28080> and login as user `admin` with password `<PASSWORD>!`.
Create a new notebook and in a cell enter the following Spark code using the Python API.
```scala
val opts = Map(
"url" -> "jdbc:postgresql://postgresql/demodb?user=demo&password=<PASSWORD>!",
"driver" -> "org.postgresql.Driver",
"dbtable" -> "flight_data.airport_t")
val df = spark
.read
.format("jdbc")
.options(opts)
.load
```
```
df.show
```

<file_sep># Using Kafka from Spring Boot with Kotlin using Kafka Spring
In this workshop we will learn how to use the **Spring Kafka** abstraction from within a Spring Boot application using the **Kotlin** language.
We will implement both a consumer and a producer implementing the same behaviour as in [Workshop 6: Working with Kafka from Kotlin](../06-producing-consuming-kafka-with-kotlin).
We will create two Spring Boot projects, one for the **Producer** and one for the **Consumer**, simulating two independent microservices interacting with eachother via events.
## Create the Spring Boot Producer
First we create an test the Producer microservice.
### Creating the Spring Boot Project
First, let’s navigate to [Spring Initializr](https://start.spring.io/) to generate our project. Our project will need the Apache Kafka support.
Select Generate a **Maven Project** with **Kotlin** and Spring Boot **2.7.0**. Enter `com.trivadis.kafkaws` for the **Group**, `spring-boot-kotlin-kafka-producer` for the **Artifact** field and `Kafka Producer project for Spring Boot` for the **Description** field.
Click on **Add Dependencies** and search for the **Spring for Apache Kafka** depencency.
Select the dependency and hit the **Enter** key. You should now see the dependency on the right side of the screen.

Once you have unzipped the project, you’ll have a very simple structure.
Import the project as a Maven Project into your favourite IDE for further development.
### Implement a Kafka Producer in Spring
Now create a simple Kotlin class `KafkaEventProducer` within the `com.trivadis.kafkaws.springbootkotlinkafkaproducer ` package, which we will use to produce messages to Kafka.
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaproducer
import org.springframework.beans.factory.annotation.Value
import org.springframework.kafka.core.KafkaTemplate
import org.springframework.kafka.support.SendResult
import org.springframework.stereotype.Component
@Component
class KafkaEventProducer (private val kafkaTemplate: KafkaTemplate<Long, String>) {
@Value("\${topic.name}")
private lateinit var kafkaTopic: String
fun produce(key: Long, value: String) {
val time = System.currentTimeMillis()
var result: SendResult<Long, String>
if (key > 0) {
result = kafkaTemplate.send(kafkaTopic, key, value).get()
} else {
result = kafkaTemplate.send(kafkaTopic, value).get()
}
val elapsedTime = System.currentTimeMillis() - time
println("[$key] sent record(key=$key value=$value) meta(partition=${result.recordMetadata.partition()}, offset=${result.recordMetadata.offset()}) time=$elapsedTime")
}
}
```
It uses the `Component` annotation to have it registered as bean in the Spring context. The topic to produce to is specified as a property, which we will specify later in the `applicaiton.yml` file.
We produce the messages synchronously. You can see that because we are using `get()` on the `send` method: `result = kafkaTemplate.send(kafkaTopic, key, value).get()`.
### Create the necessary Topics through code
Spring Kafka can automatically add topics to the broker, if they do not yet exists. By that you can replace the `kafka-topics` CLI commands seen so far to create the topics, if you like.
Spring Kafka provides a `TopicBuilder` which makes the creation of the topics very convenient.
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaproducer
import org.apache.kafka.clients.admin.NewTopic
import org.springframework.beans.factory.annotation.Value
import org.springframework.context.annotation.Bean
import org.springframework.kafka.config.TopicBuilder
import org.springframework.stereotype.Component
@Component
class TopicCreator {
@Value("\${topic.name}")
private lateinit var kafkaTopic: String
@Value("\${topic.partitions}")
private var partitions: Int = 0
@Value("\${topic.replication-factor}")
private var replicationFactor: Int = 0
@Bean
fun topic(): NewTopic? {
return TopicBuilder.name(kafkaTopic)
.partitions(partitions)
.replicas(replicationFactor)
.build()
}
}
```
We again refer to properties, which will be defined later in the `application.yml` config file.
### Add Producer logic to the SpringBootKafkaProducerApplication class
We change the generated Spring Boot application to be a console appliation by implementing the `CommandLineRunner` interface.
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaproducer
import org.springframework.boot.CommandLineRunner
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication
import org.springframework.context.annotation.Bean
import java.time.LocalDateTime
@SpringBootApplication
class SpringBootKotlinKafkaProducerApplication{
@Bean
fun init(kafkaEventProducer: KafkaEventProducer) = CommandLineRunner { args ->
val sendMessageCount = if (args.size==0) 100 else args[0].toInt()
val waitMsInBetween = if (args.size==0) 10 else args[1].toLong()
val id = if (args.size==0) 0 else args[2].toLong()
for (index in 1 .. sendMessageCount) {
val value = "[$id" + "] Hello Kafka " + index + " => " + LocalDateTime.now()
kafkaEventProducer.produce(id, value);
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
fun main(args: Array<String>) {
runApplication<SpringBootKotlinKafkaProducerApplication>(*args)
}
```
### Configure Kafka through application.yml configuration file
First let's rename the existing `application.properties` file to `application.yml` to use the `yml` format.
Add the following settings to configure the Kafka cluster and the name of the topic:
```yml
topic:
name: test-kotlin-spring-topic
replication-factor: 3
partitions: 12
spring:
kafka:
bootstrap-servers: ${DATAPLATFORM_IP}:9092
producer:
key-serializer: org.apache.kafka.common.serialization.LongSerializer
value-serializer: org.apache.kafka.common.serialization.StringSerializer
logging:
level:
root: info
```
For the IP address of the Kafka cluster we refer to an environment variable, which we have to declare before running the application.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
### Build the application
First lets build the application:
```bash
mvn package -Dmaven.test.skip=true
```
### Run the application
Now let's run the application
```bash
mvn spring-boot:run
```
Make sure that you see the messages through the console consumer.
To run the producer with custom parameters (for example to specify the key to use), use the `-Dspring-boot.run.arguments`:
```bash
mvn spring-boot:run -Dspring-boot.run.arguments="100 10 10"
```
### Use Console to test the application
In a terminal window start consuming from the output topic:
```bash
kcat -b kafka-1:19092 -t test-kotlin-spring-topic
```
## Create the Spring Boot Consumer
Now let's create an test the Consumer microservice.
### Creating the Spring Boot Project
Use again the [Spring Initializr](https://start.spring.io/) to generate the project.
Select Generate a **Maven Project** with **Kotlin** and Spring Boot **2.7.0**. Enter `com.trivadis.kafkaws` for the **Group**, `spring-boot-kotlin-kafka-consumer` for the **Artifact** field and `Kafka Consumer project for Spring Boot` for the **Description** field.
Click on **Add Dependencies** and search for the **Spring for Apache Kafka** depencency.
Select the dependency and hit the **Enter** key. You should now see the dependency on the right side of the screen.
Click on **Generate Project** and unzip the ZIP file to a convenient location for development.
Once you have unzipped the project, you’ll have a very simple structure.
Import the project as a Maven Project into your favourite IDE for further development.
### Implement a Kafka Consumer in Spring
Start by creating a simple Kotlin class `KafkaEventConsumer` within the `com.trivadis.kafkaws.springbootkafkaconsumer` package, which we will use to consume messages from Kafka.
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaconsumer
import org.apache.kafka.clients.consumer.ConsumerRecord
import org.springframework.kafka.annotation.KafkaListener
import org.springframework.stereotype.Component
@Component
class KafkaEventConsumer {
@KafkaListener(topics = ["\${topic.name}"], groupId = "simple-kotlin-consumer")
fun receive(consumerRecord: ConsumerRecord<Long, String>) {
println("received key = ${consumerRecord.key()} with payload=${consumerRecord.value()}")
}
}
```
This class uses the `Component` annotation to have it registered as bean in the Spring context and the `KafkaListener` annotation to specify a listener method to be called for each record consumed from the Kafka input topic. The name of the topic is specified as a property to be read again from the `application.yml` configuration file.
In the code we only log the key and value received to the console. In real life, we would probably inject another bean into the `KafkaEventConsumer` to perform the message processing.
### Configure Kafka through application.yml configuration file
First let's rename the existing `application.properties` file to `application.yml` to use the `yml` format.
Add the following settings to configure the Kafka cluster and the name of the two topics:
```yml
topic:
name: test-kotlin-spring-topic
spring:
kafka:
bootstrap-servers: ${DATAPLATFORM_IP}:9092
consumer:
key-deserializer: org.apache.kafka.common.serialization.LongDeserializer
value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
logging:
level:
root: info
```
For the IP address of the Kafka cluster we refer to an environment variable, which we have to declare before running the application.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
### Build the application
First lets build the application:
```bash
mvn package -Dmaven.test.skip=true
```
### Run the application
Now let's run the application
```bash
mvn spring-boot:run
```
## Various Options for Producer & Consumer
### Produce asynchronously
You can also produce asynchronously using Spring Kafka. Let's implement the `KafkaEventProducer` class in an asynchronous way:
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaproducer
import org.springframework.beans.factory.annotation.Value
import org.springframework.kafka.core.KafkaTemplate
import org.springframework.kafka.support.SendResult
import org.springframework.stereotype.Component
import org.springframework.util.concurrent.ListenableFuture
@Component
class KafkaEventProducerAsync(private val kafkaTemplate: KafkaTemplate<Long, String>) {
@Value("\${topic.name}")
private lateinit var kafkaTopic: String
fun produce(key: Long, value: String) {
val time = System.currentTimeMillis()
var future: ListenableFuture<SendResult<Long, String>>
if (key > 0) {
future = kafkaTemplate.send(kafkaTopic, key, value)
} else {
future = kafkaTemplate.send(kafkaTopic, value)
}
future.addCallback({
val elapsedTime = System.currentTimeMillis() - time
println("[$key] sent record(key=$key value=$value) meta(partition=${it?.recordMetadata?.partition()}, offset=${it?.recordMetadata?.offset()}) time=$elapsedTime")
}, {
it.printStackTrace()
})
}
}
```
To test it, switch the injection in the `SpringBootKotlinKafkaProducerApplication` class to use the `KafkaEventProducerAsync` class:
```kotlin
fun init(kafkaEventProducer: KafkaEventProducerAsync) = CommandLineRunner { args ->
```
### Adding Message Filters for Listeners
Configuring message filtering is actually very simple. You only need to configure a `RecordFilterStrategy` (message filtering strategy) for the listening container factory. When it returns `true`, the message will be discarded. When it returns `false`, the message can normally reach the listening container.
Add the following additional configuration to the `SpringBootKafkaConsumerApplication` class. Here we just discard all messages which do not contain `Kafka 5' in its value:
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaconsumer
import org.apache.kafka.clients.consumer.ConsumerRecord
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.kafka.config.ConcurrentKafkaListenerContainerFactory
import org.springframework.kafka.core.ConsumerFactory
@Configuration
class FilterConfiguration {
@Autowired
private lateinit var consumerFactory: ConsumerFactory<Long, String>
@Bean
fun filterContainerFactory(): ConcurrentKafkaListenerContainerFactory<Long, String> {
val factory = ConcurrentKafkaListenerContainerFactory<Long, String>()
factory.setConsumerFactory(consumerFactory)
factory.setRecordFilterStrategy { record: ConsumerRecord<Long, String> ->
!record.value().contains("Kafka 5")
}
return factory
}
}
```
To use this factory instead of the default one created by the Spring Boot framework, you have to specify the `containerFactory` parameter in the `@KafakListener` annotation.
```kotlin
@KafkaListener(topics = ["\${topic.name}"], groupId = "simple-kotlin-consumer", containerFactory = "filterContainerFactory")
fun receive(consumerRecord: ConsumerRecord<Long, String>) {
```
Message filtering can be used for example to filter duplicate messages.
### Commit after given number of records
Starting with version 2.3, Spring Kafka sets `enable.auto.commit` to `false` unless explicitly set in the configuration. Previously, the Kafka default (true) was used if the property was not set.
If `enable.auto.commit` is false, the containers support several `AckMode` settings ([see documentation](https://docs.spring.io/spring-kafka/reference/html/#committing-offsets)). The default AckMode is `BATCH`, which commit the offset when all the records returned by the `poll()` have been processed. Other options allow to commit manually, after a given time has passed or after a given number of records have been consumed.
To commit offsets after a given number of records have been processed, switch the `AckMode` from `batch` to `count` and add the `ackCount` configuration to the `application.yml` file:
```yml
spring:
kafka:
bootstrap-servers: ${DATAPLATFORM_IP}:9092
consumer:
key-deserializer: org.apache.kafka.common.serialization.LongDeserializer
value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
listener:
ack-mode: count
ack-count: 40
```
To check that commits are done after 40 records, you can consume from the `__consumer_offsets` topic using the following enhanced version of the `kafka-console-consumer`:
```bash
docker exec -ti kafka-1 kafka-console-consumer --formatter "kafka.coordinator.group.GroupMetadataManager\$OffsetsMessageFormatter" --bootstrap-server kafka-1:19092 --topic __consumer_offsets
```
An alternative way to check for the commits is to set the logging of the `ConsumerCoordinator` to debug
```yml
logging:
level:
root: info
org:
apache:
kafka:
clients:
consumer:
internals:
ConsumerCoordinator: debug
```
### Manual Commit when consuming records
In the `@KafkaListener` method, add an additional parameter to get the `acknowledgment` bean on which you can invoke the `acknowledge()` method.
```kontlin
class KafkaEventConsumer {
@KafkaListener(topics = ["\${topic.name}"], groupId = "simple-kotlin-consumer", containerFactory = "filterContainerFactory")
fun receive(consumerRecord: ConsumerRecord<Long, String>, acknowledgment: Acknowledgment) {
println("received key = ${consumerRecord.key()} with payload=${consumerRecord.value()}")
acknowledgment.acknowledge();
}
}
```
Set the `ack-mode` to `manual` in the `application.yml`.

# Handle Serialization Errors in ksqlDB
This recipe will show how to find serialization errors that cause some events from a Kafka topic to not be written into a ksqlDB stream or table.
The example code shown in this cookbook recipe is taken from the Confluent tutorial ["How to handle deserialization errors"](https://developer.confluent.io/tutorials/handling-deserialization-errors/ksql.html).
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services KAFKA,KAFKA_KSQLDB -s trivadis/platys-modern-data-platform -w 1.16.0
```
start the platform
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
## Create the input topic with a stream
To start off the implementation of this scenario, you need to create a stream that represent sensors. This stream will contain a field called ENABLED to indicate the status of the sensor. While this stream acts upon data stored in a topic called `SENSORS_RAW`, we will create derived stream called `SENSORS` to actually handle the sensors. This stream simply copies the data from the previous stream, ensuring that the ID field is used as the key.
Connect to ksqldb cli
```bash
docker exec -it ksqldb-cli ksql http://ksqldb-server-1:8088
```
and create the two streams
```sql
CREATE STREAM SENSORS_RAW (id VARCHAR, timestamp VARCHAR, enabled BOOLEAN)
WITH (KAFKA_TOPIC = 'SENSORS_RAW',
VALUE_FORMAT = 'JSON',
TIMESTAMP = 'TIMESTAMP',
TIMESTAMP_FORMAT = 'yyyy-MM-dd HH:mm:ss',
PARTITIONS = 1);
CREATE STREAM SENSORS AS
SELECT
ID, TIMESTAMP, ENABLED
FROM SENSORS_RAW
PARTITION BY ID;
```
## Produce events to the input topic
Before we move forward with the implementation, we need to produce records to the `SENSORS_RAW` topic, that as explained earlier, is the underlying topic behind the `SENSORS` stream. Let’s use the console producer to create some records.
```bash
docker exec -i kafka-1 /usr/bin/kafka-console-producer --bootstrap-server kafka-1:19092 --topic SENSORS_RAW
```
Type in one line at a time and press enter to send it. Each line represents a sensor with the required data. Note that for testing purposes, we are providing two records with data in the right format (notably the first two records) and one record with an error. The record with the error contains the field `ENABLED` specified as string instead of a boolean.
```json
{"id": "e7f45046-ad13-404c-995e-1eca16742801", "timestamp": "2020-01-15 02:20:30", "enabled": true}
{"id": "835226cf-caf6-4c91-a046-359f1d3a6e2e", "timestamp": "2020-01-15 02:25:30", "enabled": true}
{"id": "1a076a64-4a84-40cb-a2e8-2190f3b37465", "timestamp": "2020-01-15 02:30:30", "enabled": "true"}
```
## Checking for deserialization errors
Create a new client session for KSQL using the following command:
```bash
docker exec -it ksqldb-cli ksql http://ksqldb-server-1:8088
```
We know that we produced three records to the stream but only two of them were actually correct. In order to check if these two records were properly written into the stream, run the pull query (without the `EMIT CHANGES` clause) below
```sql
SELECT
ID,
TIMESTAMP,
ENABLED
FROM SENSORS;
```
and the output should look similar to:
```
+--------------------------------------------------------+--------------------------------------------------------+--------------------------------------------------------+
|ID |TIMESTAMP |ENABLED |
+--------------------------------------------------------+--------------------------------------------------------+--------------------------------------------------------+
|e7f45046-ad13-404c-995e-1eca16742801 |2020-01-15 02:20:30 |true |
|e7f45046-ad13-404c-995e-1eca16742801 |2020-01-15 02:20:30 |true |
|e7f45046-ad13-404c-995e-1eca16742801 |2020-01-15 02:20:30 |true |
Query Completed
Query terminated
```
We know that at least one of the records produced had an error, because we specified the field ENABLED as a string instead of a boolean.
With the [KSQL Processing Log](https://docs.ksqldb.io/en/latest/reference/processing-log) feature enabled, you can query a stream called KSQL_PROCESSING_LOG to check for deserialization errors.
The query below is extracting some of the data available in the processing log. As the ksqldb-server is configured so that the processing log includes the payload of the message, we can also use the encode method to convert the record from `base64` encoded into a human readable `utf8` encoding:
```sql
SELECT
message->deserializationError->errorMessage,
message->deserializationError->`topic`,
encode(message->deserializationError->RECORDB64, 'base64', 'utf8') AS MSG,
message->deserializationError->cause
FROM KSQL_PROCESSING_LOG;
```
this query should produce the following output
```
+-----------------------------------------+-----------------------------------------+-----------------------------------------+-----------------------------------------+
|ERRORMESSAGE |topic |MSG |CAUSE |
+-----------------------------------------+-----------------------------------------+-----------------------------------------+-----------------------------------------+
|Failed to deserialize value from topic: S|SENSORS_RAW |{"id": "1a076a64-4a84-40cb-a2e8-2190f3b37|[Can't convert type. sourceType: TextNode|

|e: TextNode, requiredType: BOOLEAN, path:| | "enabled": "true"} | Can't convert type. sourceType: TextNode|

# Trino Security
This recipe will show how to use [Trino](http://trino.io) with [security enabled](https://trino.io/docs/current/security/overview.html). We will first enable [TLS and HTTPS](https://trino.io/docs/current/security/tls.html) with [Password File Authentication](https://trino.io/docs/current/security/password-file.html) and then in a second step we will also enable [File-based access control](https://trino.io/docs/current/security/file-system-access-control.html).
## Initialise data platform
First [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services TRINO,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.16.0
```
Before we can generate the platform, we need to extend the `config.yml`:
## Add Authentication
Enable authentication by adding the following settings to the `config.yml`
```
TRINO_auth_enabled: true
TRINO_auth_use_custom_password_file: false
TRINO_auth_with_groups: false
```
Now set an environment variable to the home folder of the dataplatform and generate the data platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
```
Platys uses a self-signed certificate for TLS, you can create you own certificate.
It also uses the [Password File Authentication](https://trino.io/docs/current/security/password-file.html) type of Trino and for that a password file is needed. By default a password file with 3 users (`admin`, `userA` and `userB`) with password `<PASSWORD>!` is used.
### Create a custom Password file (optional)
You can use your own password file and add your own users. For that you need to enable `TRINO_auth_use_custom_password_file` and then create the password file using
```bash
cd $DATAPLATFORM_HOME
touch custom-conf/trino/security/password.db
```
Now add or update the password for a user (replace `<new-user>` by the username).
```bash
htpasswd -B -C 10 custom-conf/trino/security/password.db <new-user>
```
### Create Custom Certificates (optional)
You can create your own certificate and add it to a keystore. For that you need to enable `TRINO_auth_use_custom_certs` and then create the self-signed certificate and add it to the keystore using these commands
```bash
cd $DATAPLATFORM/custom-conf/trino

```
### Start the platform
Now start the data platform.
```bash
docker-compose up -d
```
## Test Authentication
First let's see what happens if we use the Trino CLI without specifying a user and still over HTTP port:
```bash
docker exec -it trino-cli trino --server trino-1:8080
```
if we execute the SQL statement `SELECT * FROM system.runtime.nodes` we can see a HTTP `403` error.
```bash
trino> SELECT * FROM system.runtime.nodes;
Error running command: Error starting query at http://trino-1:8080/v1/statement returned an invalid response: JsonResponse{statusCode=403, headers={cache-control=[must-revalidate,no-cache,no-store], content-length=[422], content-type=[text/html;charset=iso-8859-1]}, hasValue=false} [Error: <html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>
<title>Error 403 Forbidden</title>
</head>
<body><h2>HTTP ERROR 403 Forbidden</h2>
<table>
<tr><th>URI:</th><td>/v1/statement</td></tr>
<tr><th>STATUS:</th><td>403</td></tr>
<tr><th>MESSAGE:</th><td>Forbidden</td></tr>
<tr><th>SERVLET:</th><td>org.glassfish.jersey.servlet.ServletContainer-5810772a</td></tr>
</table>
</body>
</html>
]
```
we have to specify the `8443` port for using HTTPs, the username and the keystore to use:
```bash
docker exec -it trino-cli trino --server https://trino-1:8443 --user admin --password --insecure --keystore-path /etc/trino/trino.jks --keystore-password <PASSWORD>!
```
Use `<PASSWORD>!` for the password.
if we now execute the SQL statement `SELECT * FROM system.runtime.nodes` we can see that it works
```bash
trino> SELECT * FROM system.runtime.nodes;
node_id | http_uri | node_version | coordinator | state
---------+------------------------+--------------+-------------+--------
trino-1 | http://172.19.0.4:8080 | 407 | true | active
(1 row)
Query 20230225_215138_00001_fd6cc, FINISHED, 1 node
Splits: 1 total, 1 done (100.00%)
0.20 [1 rows, 39B] [4 rows/s, 194B/s]
```
## Add Authorization
Enable authorization by adding the following settings to the `config.yml`
```
TRINO_access_control_enabled: true
```
Regenerate the platform.
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
```
### Configure the access control rules file
Create a file `rules.json` in `custom-conf/trino/security/` and add the following configuration
```json
{
"catalogs": [
{
"catalog": "system",
"allow": "none"
}
]
}
```
With this configuration, we disallow access to the system catalog for all users.
Now update the platform using
```bash
docker-compose up -d
```
## Test Authorization
Let's test if the authorization works by using the Trino CLI
```bash
docker exec -it trino-cli trino --server https://trino-1:8443 --user admin --password --insecure --keystore-path /etc/trino/trino.jks --keystore-password <PASSWORD>!
```
Use `<PASSWORD>!` for the password.
if we now execute the SQL statement `SELECT * FROM system.runtime.nodes` we can see that we get an access denied error!
```bash
trino> SELECT * FROM system.runtime.nodes
-> ;
Query 20230225_221051_00000_guu2i failed: Access Denied: Cannot access catalog system
```

### Installing JDBC Driver
If you want to use one of the Database Processors, you need to install a JDBC Driver for the database. Download it into `./plugins/nifi/jars` of your Platys stack and specify the folder `/extra-jars` folder when creating the Controller service in Apache NiFi.
### AWS (S3) Credentials
Platys automatically creates the file `/opt/nifi/nifi-current/s3-credentials.properties` in the `nifi-1` container with the AWS credentials configured for either Minio or External S3. It is meant to be used as the **Credentials File** in either one of the AWS/S3 related processors or the [AWSCredentialsProviderControllerService](https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-aws-nar/latest/org.apache.nifi.processors.aws.credentials.provider.service.AWSCredentialsProviderControllerService/index.html).
Platys also injects the following environment variables into the `nifi-1` container.
* `S3_ENDPOINT` - the S3 endpoint to use
* `S3_PATH_STYLE_ACCESS` - if path style access should be used
* `S3_REGION` - the AWS region to use

# Creating a self-managed StreamSets DataOps Environment using Platys
This recipe will show how to create a self-managed environment for the [StreamSets DataOps Platform](https://streamsets.com/products/dataops-platform/).
## Signup for StreamSets DataPlatform
Navigate to <https://cloud.login.streamsets.com/signup> and create an account as shown in the diagram.
Click on **Create Account**. Verify the account using the link in the email you should have received on the emial provided.
Now login to the newly created account and fill in the account details and click on **Agree & Continue**
and you will get to the StreamSets DataOps homepage
## Create a StreamSets Data Collector deployment
In the navigator to the left, click on **Set Up** and navigate to the **Environments** item. You should see a default Self-Managed environment **Default Self-Managed Environment**. We will use this and next create a deployment.
Navigate to **Deployments** and click on the **Create deployment** link in the main canvas.
Scroll down and click on **Save & Next**.
On the next step, click on the link **3 stage libraries selected**
to configure additional libraries to be installed. On the rigtht side, the installed stage libraries are shown, on the left side, the available stage libraries can be found. Install a library by clicking on the **+** icon.
Once you are finished, click on **OK** to go back the configuration of the deployment.
Now click once again on **Save & Next**. Chose `Docker Image` for the **Install Type**.
Click on **Save & Next** and again **Save & Next** and the **Start & Generate Install Script** and you should see the script to start the docker container.
Leave the screen open, we will need the environment variables when configuring the service in `platys`.
```
docker run -d -e STREAMSETS_DEPLOYMENT_SCH_URL=https://eu01.hub.streamsets.com -e STREAMSETS_DEPLOYMENT_ID=68f53dc7-1aa7-44b8-a8e5-f73ac9da041c:14e83b51-91b3-11ec-a4ba-f369fd3f0937 -e STREAMSETS_DEPLOYMENT_TOKEN=XXXXXX streamsets/datacollector:4.4.0
```
The deployment-token has been replaced, the real value will be much larger.
## Initialise data platform
Now let's [initialise a platys-supported data platform](../documentation/getting-started) with the following services enabled
```
platys init --enable-services STREAMSETS_DATAOPS -s trivadis/platys-modern-data-platform -w 1.14.0
```
Either add the value of `STREAMSETS_DEPLOYMENT_ID` and `STREAMSETS_DEPLOYMENT_TOKEN` to the `config.yml`
```
STREAMSETS_DATAOPS_deployment_id: '68f53dc7-1aa7-44b8-a8e5-f73ac9da041c:14e83b51-91b3-11ec-a4ba-f369fd3f0937'
STREAMSETS_DATAOPS_deployment_token: 'XXXXXX'
```
or add the environment variables to the environment, for example by using the `.env` file
```
STREAMSETS_DATAOPS_DEPLOYMENT_ID=68f53dc7-1aa7-44b8-a8e5-f73ac9da041c:14e83b51-91b3-11ec-a4ba-f369fd3f0937
STREAMSETS_DATAOPS_DEPLOYMENT_TOKEN=<PASSWORD>XX
```
The URL by default is set to `https://eu01.hub.streamsets.com`. If you need another value, then specify it in the `config.yml` file using the property `STREAMSETS_DATAOPS_deployment_sch_url`.
## Check the status in Streamsets DataOps Platform
In StreamSets DataOps Platform screen, click on **Check Engine Status after runing the script**, if you have not done it yet.
Now generate and start the platform
```bash
export DATAPLATFORM_HOME=${PWD}
platys gen
docker-compose up -d
```
In StreamSets DataOps Platform after a while you should get the following confirmation message.
The engine running in docker has successfully connected to the StreamSets DataOps Platform. Click on **Close**.
The environment is ready to be used.

In this workshop we will learn how to produce and consume messages from **Kotlin** using the [Kafka Java API](https://kafka.apache.org/documentation/#api) with Avro for serialising and deserialising messages.
## Create the project in your favourite IDE
Create a new Maven Project (using the functionality of your IDE) and in the last step use `com.trivadis.kafkaws` for the **Group Id** and `kotlin-simple-kafka-avro` for the **Artifact Id**.
Navigate to the **pom.xml** and double-click on it. The POM Editor will be displayed.
You can either use the GUI to edit your `pom.xml` or navigate to the last tab **pom.xml** to switch to the "code view". Let's do that.
You will see the still rather empty definition.
```xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>com.trivadis.kafkaws</groupId>
<artifactId>kotlin-simple-kafka-avro</artifactId>
<version>0.0.1-SNAPSHOT</version>

```
Let's add some initial dependencies for our project. We will add some more dependencies to the POM throughout this workshop.

## Creating the necessary Kafka Topic
We will use the topic `test-kotlin-avro-topic` in the Producer and Consumer code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
In a terminal window, connect to the `kafka-1` container
```
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```
kafka-topics --create \
--replication-factor 3 \
--partitions 12 \
--topic test-kotlin-avro-topic \
--bootstrap-server kafka-1:19092,kafka-2:19093
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing the **Kafka Producer** which uses Avro for the serialisation.
## Create an Avro Schema representing the Notification Message
First create a new Folder `avro` under the existing folder **src/main/**.
Create a new File `Notification-v1.avsc` in the folder **src/main/avro** just created above.
Add the following Avro schema to the empty file.
```json
{
"type" : "record",
"namespace" : "com.trivadis.kafkaws.avro.v1",
"name" : "Notification",
"description" : "A simple Notification Event message",
"fields" : [
{ "type" : ["long", "null"],
"name" : "id"
},
{ "type" : ["string", "null"],
"name" : "message"
}
]
}
```
In the `pom.xml`, add the `avro-maven-plugin` plugin to the `<build><plugins>` section, just below the `exec-maven-plugin`.
```xml
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<version>${avro.version}</version>

```
This plugin will make sure, that classes are generated based on the Avro schema, whenever a `mvn compile` is executed. Let's exactly do that on the still rather empty project.
```
mvn compile
```
After running this command, refresh the project and you should see a new folder named `target/generated-sources/avro`. Expand into this folder and you should see one generated Java class named `Notification`.
Double click on the `Notification` class to inspect the code.
```kotlin
package com.trivadis.kafkaws.avro.v1;
import org.apache.avro.specific.SpecificData;
@SuppressWarnings("all")
@org.apache.avro.specific.AvroGenerated
public class Notification extends org.apache.avro.specific.SpecificRecordBase implements org.apache.avro.specific.SpecificRecord {
private static final long serialVersionUID = 799361421243801515L;
public static final org.apache.avro.Schema SCHEMA$ = new org.apache.avro.Schema.Parser().parse("{\"type\":\"record\",\"name\":\"Notification\",\"namespace\":\"com.trivadis.kafkaws.avro.v1\",\"fields\":[{\"name\":\"id\",\"type\":[\"long\",\"null\"]},{\"name\":\"message\",\"type\":[\"string\",\"null\"]}],\"description\":\"A simple Notification Event message\"}");
public static org.apache.avro.Schema getClassSchema() { return SCHEMA$; }
private java.lang.Long id;
private java.lang.CharSequence message;
/**
* Default constructor. Note that this does not initialize fields
* to their default values from the schema. If that is desired then
* one should use <code>newBuilder()</code>.
*/
public Notification() {}
/**
* All-args constructor.
* @param id The new value for id
* @param message The new value for message
*/
public Notification(java.lang.Long id, java.lang.CharSequence message) {
this.id = id;
this.message = message;
}
...
```
You can see that the code is based on the information in the Avro schema. We will use this class when we produce as well as consume Avro messages to/from Kafka.
Add an addtional source folder to the `kotlin-maven-plugin` so that Maven can find the generated classes
```xml

## Create a Kafka Producer using Avro for serialisation
First create a new Package `com.trivadis.kafkaws.producer` in the folder **src/main/kotlin**.
Create a new Kotlin File `KafkaProducerAvro` in the package `com.trivadis.kafakws.producer` just created.
Add the following code to the empty class to create a Kafka Producer. It is similar to the code we have seen in the previous workshop. We have changed both serialiser to use the Confluent `KafkaAvroSerializer` class and added the URL to the Confluent Schema Registry API.
We will be using the synchronous way for producing messages to the Kafka topic we created above, but the other methods would work as well with Avro.
```kotlin
@file:JvmName("KafkaProducerAvro")
package com.trivadis.kafkaws.producer
import com.trivadis.kafkaws.avro.v1.Notification
import io.confluent.kafka.serializers.KafkaAvroSerializer
import io.confluent.kafka.serializers.KafkaAvroSerializerConfig
import org.apache.kafka.clients.producer.KafkaProducer
import org.apache.kafka.clients.producer.ProducerConfig.*
import org.apache.kafka.clients.producer.ProducerRecord
import org.apache.kafka.common.serialization.LongSerializer
import java.time.LocalDateTime
import java.util.*
private val TOPIC = "test-kotlin-avro-topic"
private val BOOTSTRAP_SERVERS = "dataplatform:9092,dataplatform:9093"
private val SCHEMA_REGISTRY_URL = "http://dataplatform:8081"
fun runProducer(sendMessageCount: Int, waitMsInBetween: Long, id: Long) {
// Define properties.
val props = Properties()
props[BOOTSTRAP_SERVERS_CONFIG] = BOOTSTRAP_SERVERS
props[ACKS_CONFIG] = "all"
props[KEY_SERIALIZER_CLASS_CONFIG] = KafkaAvroSerializer::class.qualifiedName
props[VALUE_SERIALIZER_CLASS_CONFIG] = KafkaAvroSerializer::class.qualifiedName
props[KafkaAvroSerializerConfig.SCHEMA_REGISTRY_URL_CONFIG] = SCHEMA_REGISTRY_URL
val key = if (id > 0) id else null
KafkaProducer<Long, Notification>(props).use { producer ->
repeat(sendMessageCount) { index ->
val time = System.currentTimeMillis();
//val notification = Notification(id, "test")
val notification = Notification.newBuilder().setId(id)
.setMessage("[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now()).build()
val m = producer.send(ProducerRecord(TOPIC, key, notification)).get()
val elapsedTime = System.currentTimeMillis() - time;
println("Produced record to topic ${m.topic()} partition [${m.partition()}] @ offset ${m.offset()} time=${elapsedTime}")
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
producer.flush()
}
}
```
Next you define the main method.
```kotlin
fun main(args: Array<String>) {
if (args.size == 0) {
runProducer(100, 10, 0)
} else {
runProducer(args[0].toInt(), args[1].toLong(), args[2].toLong())
}
}
```
The `main()` method accepts 3 parameters, the number of messages to produce, the time in ms to wait in-between sending each message and the ID of the producer.
Use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-java-avro-topic `.
```
kcat -b kafka-1:19092 -t test-kotlin-avro-topic
```
Now run it using the `mvn exec:java` command. It will generate 1000 messages, waiting 10ms in-between sending each message and use 0 for the ID.
```
mvn exec:java@producer -Dexec.args="1000 10 0"
```
You can see that `kcat` shows some special, non-printable characters. This is due to the Avro format. If you want to display the Avro, you can use the `kafka-avro-console-consumer` CLI, which is part of the Schema Registry.
So let's connect to the schema registry container:
```
docker exec -ti schema-registry-1 bash
```
And then invoke the `kafka-avro-console-consumer` similar to the "normal" consumer seen so far.
```
kafka-avro-console-consumer --bootstrap-server kafka-1:19092 --topic test-kotlin-avro-topic
```
You should see an output similar to the one below.
```
...

{"id":{"long":0},"message":{"string":"[0] Hello Kafka 15 => 2022-06-04T20:45:08.604500"}}
...
```
if you want to consume with `kcat` you need to specify the serialization format `-s` and the address of the schema registry `-r`:
```
kcat -b kafka-1 -t test-kotlin-avro-topic -s value=avro -r http://schema-registry-1:8081
```
**Note**: For Avro support your kafkacat/kcat version needs to be `1.6' or later.
## View the Schema in the Registry
The Avro Serialiser and Deserialiser automatically register the Avro schema, if it is not already in the registry.
The Streamingplatform also contains a tool made by a company called Landoop which allows us to see what's in the registry.
In a browser, navigate to <http://dataplatform:28039> and you should see the home page of the Schema Registry UI.
If you click on the schema to the left, you can view the details of the schema. You can see that version v1 has been assigned automatically.
## Create a Kafka Consumer using Avro for serialization
First create a new Package `com.trivadis.kafkaws.consumer` in the folder **src/main/kotlin**.
Create a new Java Class `KafkaConsumerAvro` in the package `com.trivadis.kafakws.consumer` just created.
Add the following code to the empty class.
```kotlin
@file:JvmName("KafkaConsumerAvro")
package com.trivadis.kafkaws.consumer
import com.trivadis.kafkaws.avro.v1.Notification
import io.confluent.kafka.serializers.KafkaAvroDeserializer
import io.confluent.kafka.serializers.KafkaAvroSerializerConfig
import org.apache.kafka.clients.consumer.ConsumerConfig.*
import org.apache.kafka.clients.consumer.KafkaConsumer
import org.apache.kafka.common.serialization.LongDeserializer
import org.apache.kafka.common.serialization.StringDeserializer
import java.time.Duration
import java.util.*
private val TOPIC = "test-kotlin-avro-topic"
private val BOOTSTRAP_SERVERS = "dataplatform:9092,dataplatform:9093"
private val SCHEMA_REGISTRY_URL = "http://dataplatform:8081"
fun runConsumerManual(waitMsInBetween: Long) {
// Define properties.
val props = Properties()
props[BOOTSTRAP_SERVERS_CONFIG] = BOOTSTRAP_SERVERS
props[GROUP_ID_CONFIG] = "kotlin-simple-avro-consumer"
props[ENABLE_AUTO_COMMIT_CONFIG] = false
props[KEY_DESERIALIZER_CLASS_CONFIG] = KafkaAvroDeserializer::class.qualifiedName
props[VALUE_DESERIALIZER_CLASS_CONFIG] = KafkaAvroDeserializer::class.qualifiedName
props[KafkaAvroSerializerConfig.SCHEMA_REGISTRY_URL_CONFIG] = SCHEMA_REGISTRY_URL
val consumer = KafkaConsumer<Long, Notification>(props).apply {
subscribe(listOf(TOPIC))
}
consumer.use {
while(true) {
val messages = consumer.poll(Duration.ofMillis(100))
messages.forEach {
println("Consumed record [Key: ${it.key()}, Value: ${it.value()}] @ Partition: ${it.partition()}, Offset: ${it.offset()}")
}
consumer.commitSync();
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
fun main(args: Array<String>) {
if (args.size == 0) {
runConsumerManual(10)
} else {
runConsumerManual(args[0].toLong())
}
}
```
Now compile and start the consumer
```bash
mvn clean package
mvn exec:java@consumer
```
## Register in Schema Registry using Maven
In the test above, the Avro schema has been registered in the schema registry when starting the Producer for the first time. To register an Avro schema through Maven automatically, you can use the following Maven plugin.
Add the following definition to the `pom.xml`.
```xml
<plugin>
<groupId>io.confluent</groupId>
<artifactId>kafka-schema-registry-maven-plugin</artifactId>
<version>3.2.0</version>
<configuration>
<schemaRegistryUrls>
<param>http://dataplatform:8081</param>
</schemaRegistryUrls>
<subjects>
<test-java-avro-topic-value>src/main/avro/Notification-v1.avsc</test-java-avro-topic-value>
</subjects>
</configuration>
<goals>
<goal>register</goal>
<goal>test-compatibility</goal>
</goals>
</plugin>
```
Now you can use the following command to register the schemas with the Schema Registry:
```
mvn schema-registry:register
```

# Querying data in Minio (S3) from Trino (formerly PrestoSQL)
This tutorial will show how to query Minio with Hive and Trino.
## Initialise a platform
First [initialise a platys-supported data platform](../../getting-started) with the following services enabled
```
platys init --enable-services TRINO,HIVE_METASTORE,MINIO,AWSCLI,PROVISIONING_DATA -s trivadis/platys-modern-data-platform -w 1.11.0
```
add the following property to `config.yml`
```
TRINO_edition: 'oss'
```
Now generate and start the data platform.
```bash
platys gen
docker-compose up -d
```
## Create Data in Minio
create the bucket
```
docker exec -ti awscli s3cmd mb s3://flight-bucket
```
and upload some data
```
docker exec -ti awscli s3cmd put /data-transfer/flight-data/airports.json s3://flight-bucket/landing/airports/airports.json
docker exec -ti awscli s3cmd put /data-transfer/flight-data/plane-data.json s3://flight-bucket/landing/plane/plane-data.json
```
## Create a table in Hive
On the docker host, start the Hive CLI
```
docker exec -ti hive-metastore hive
```
and create a new database `flight_db` and in that database a table `plane_t`:
```
create database flight_db;
use flight_db;
CREATE EXTERNAL TABLE plane_t (tailnum string
, type string
, manufacturer string , issue_date string
, model string
, status string
, aircraft_type string
, engine_type string
, year string )
ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
LOCATION 's3a://flight-bucket/landing/plane';
```
## Query Table from Trino
Next let's query the data from Trino. Connect to the Trino CLI using
```
docker exec -it trino-cli trino --server trino-1:8080
```
Now on the Trino command prompt, switch to the right database.
```
use minio.flight_db;
```
Let's see that there is one table available:
```
show tables;
```
We can see the `plane_t` table we created in the Hive Metastore before
```
presto:default> show tables;
Table
---------------
plane_t
(1 row)
```
```
SELECT * FROM plane_t;
```
```
SELECT year, count(*)
FROM plane_t
GROUP BY year;

Navigate to <http://dataplatform:28155><file_sep># Function as a Service (FaaS) with Kafka and Nuclio
In this workshop we will learn how to use [Nuclio](https://nuclio.io/) to implement serverless functions to consume from Kafka. We will be using Python to implement the function.
You can find many examples of using Nuclio with various languages [here](https://nuclio.io/docs/latest/examples/).
This guide assumes that you already have a dataplatform with Kafka and Nuclio available.
We will be using the [Streaming Synthetic Sales Data Generator](https://github.com/garystafford/streaming-sales-generator) we have used in [Getting started with Apache Kafka](./02-working-with-kafka-broker) to produce sales orders to a Kafka topic. Nuclio will then be used to consume the messages and process them with a serverless functions.
For the creation of the serverless function, we will use the [Nuclio GUI](http://dataplatform:8070).
## Setup
### Creating the necessary Kafka Topics
Let's create the necessary 3 topics, if they no longer exist:
```bash
docker exec -ti kafka-1 kafka-topics --create --bootstrap-server kafka-1:19092 --topic demo.products --replication-factor 3 --partitions 8
docker exec -ti kafka-1 kafka-topics --create --bootstrap-server kafka-1:19092 --topic demo.purchases --replication-factor 3 --partitions 8
docker exec -ti kafka-1 kafka-topics --create --bootstrap-server kafka-1:19092 --topic demo.inventories --replication-factor 3 --partitions 8
```
## Working with Nuclio
Let's navigate to the [Nuclio GUI](http://dataplatform:8070). You should see the projects, with the **default** project being the only one available.
Let's create a new project by clicking **NEW PROJECT**. In the pop-up window, enter `kafka-workshop` for **Project name** and `Kafka Workshop` for the **Description** and click **CREATE**. The new project should appear in the list of projects.
Navigate into the newly created project and you will see the 3 different options to **Start a new function**:
Let's start from scratch by clicking on **Start from scratch**. Enter `consume-purchases` into **Name**, select `Python 3.9` for the **Runtime** and click **CREATE**.
A new page will appear, with the function code to the left.
Let's implement the handler
```python
def handler(context, event):
body = event.body.decode('utf-8')
context.logger.info('New message received from Kafka:' + body)
return ""
```
Navigate to **TRIGGERS**
and click on **Create a new trigger**
Enter `kafka-purchases` into the **Name** field and select `Kafka` from the **Class** drop-down.
Now enter `kafka-1:19092` into the **Brokers** field, `demo.purchases` into the **Topics** field and `nuclio-purchases-cg` into the **Consumer group name**. Select `3` for the **Max workers** drop-down. We don't need to change any of the **Advanced** options.
Navigate back to **CODE**. As we have used the container name of Kafka to connect to the Kafka broker, we have to make sure, that the Docker container, Nuclio will create for the function is started in the same network as the Kafka cluster.
We can not control that over the Nuclio GUI, but it is available as an [inline configuration snippet](https://github.com/nuclio/nuclio/blob/master/docs/tasks/deploying-functions.md#providing-configuration-via-inline-configuration) in your functions source code
```
# @nuclio.configure
# function.yaml:
# spec:
# platform:
# attributes:
# network: kafka-workshop
def handler(context, event):
context.logger.info('message received from Kafka')
return ""
```
Click on **DEPLOY** to deploy the serverless function for the first time. You should see a **Successfully deployed** message.
Let's do a `docker ps | grep nuclio` to see the docker container started by
```bash
$ docker ps | grep nuclio
bbdfd35cb484 nuclio/processor-consume-purchases:latest "processor" 32 second ago Up Less than 31 second 0.0.0.0:32770->8080/tcp nuclio-nuclio-consume-purchases

```
We can see that a new container named `nuclio-nuclio-consume-purchases` has been started a few seconds ago. This is the container running the Nuclio serverless function.
Now let's quickly test that the serverless function is invoked. We are not yet using the simulator but only send one single example message using `kcat`.
Before we send to Kafka, let's see the log of the container where the function is running in
```bash
docker logs -f nuclio-nuclio-consume-purchases
```
And in another terminal, now let's send a sample message.
Add the following sample purchase to a file named `purchase-1.json`
```json
{
"transaction_time": "2023-08-12 18:53:00.114048",
"transaction_id": "6951846465568416216",
"product_id": "SF07",
"price": 5.99,
"quantity": 1,
"is_member": true,
"member_discount": 0.1,
"add_supplements": false,
"supplement_price": 0.0,
"total_purchase": 5.39
}
```
Now use `kcat` to send the message to the Kafka topic
```bash
kcat -b dataplatform -t demo.purchases -P purchase-1.json
```
and you should see the output of the log message from the serverless function in the log of the container
```bash
$ docker logs -f nuclio-nuclio-consume-purchases
...

23.08.13 17:43:00.537 er.kafka-purchases.sarama (D) Sarama: client/metadata fetching metadata for all topics from broker kafka-1:19092
23.08.13 17:52:40.359 -cluster.w0.python.logger (I) New message received from Kafka:{

"transaction_id": "6951846465568416216",
"product_id": "SF07",
"price": 5.99,
"quantity": 1,

23.08.13 17:53:00.536 er.kafka-purchases.sarama (D) Sarama: client/metadata fetching metadata for all topics from broker kafka-1:19092
```
So the basic functionality of retrieving a message from Kafka works. Now let's add some functionality to process the message. We will simply write each message to a Redis Key/Value store.
For Redis will use the [`redis-py`](https://github.com/redis/redis-py#advanced-topics) Python Redis client. We can install it into the container by adding it to the Configuration of the image.
In the Nuclio GUI, navigate back to the `consume-purchases` function and select the **CONFIGURATION** tab. Scroll down to the **Build** canvas and add `pip install redis` to the **Build commands** edit field.
Again click on **DEPLOY** to redeploy the container. You can also click on **STATUS** to see the log of the deployment
Again the deployment should be successful.
Now let's add the necessary code to the function.
The `body` we get into the function is of type String. So we are using the built-in `json` package to parse the JSON string into a Python dictionary.
Next we connect to Redis using the `redis` package and then use the `set` command to add the purchase document as a value to Redis, using the `transaction_id` as the key. We will add it to Redis with a time to live of 120 seconds.
```python
# @nuclio.configure
# function.yaml:
# spec:
# platform:
# attributes:
# network: kafka-workshop
import redis
import json
def handler(context, event):
body = event.body.decode('utf-8')
body_json = json.loads(body)
context.logger.info('New message received from Kafka:' + body)
r = redis.Redis(host='redis-1', port=6379, password='<PASSWORD>!', db=0)
r.set(body_json["transaction_id"], body, ex=120)
return ""
```
Let's test it once again with our sample purchase message:
```bash
kcat -b dataplatform -t demo.purchases -P purchase-1.json
```
Navigate to Redis Commander on <http://dataplatform:28119> to see the new entry:
It will automatically "disappear" once the 120 seconds have expired.
Now let's see the solution in action using the Sales Data Generator to generate messages.
```bash
docker run -ti --network kafka-workshop trivadis/sales-data-generator:latest
```
Refresh the Redis Commander window to see new key/value pairs constantly be added and after 120 seconds being automatically removed.

In this workshop we will learn how to use the **Spring Kafka** abstraction with **Avro message serialization** from within a Spring Boot application using the **Kotlin** language.
We will create two Spring Boot projects, one for the **Producer** and one for the **Consumer**, simulating two independent Microservices interacting with each other via events.
Additionally we will create another Maven project called `meta` which holds the Avro Schema(s). A dependency to that project will be added to both Spring Boot projects.
## Create the Avro Metadata Project
First we will define the Avro schema and generate the classes. As both Microservices will need the generated class to work, we do that in a separate project, and then use it as a dependency in the two Microservices.
### Create a new Maven project
From your IDE (screenshot taken from IntelliJ), create a new Maven project and use `meta` for the **Name**, `com.trivadis.kafkaws.meta` for the **GroupId** and leave the **Version** as is.
Click on **Finish**.
### Add some configuration to Maven pom
Edit the `pom.xml` and . First add an additional property to the `<properties>`
```xml
<properties>
...
<avro.version>1.11.0</avro.version>
</properties>
```
and now add the dependency to [Avro](https://mvnrepository.com/artifact/org.apache.avro/avro) right after the `</properties>` element
```xml
<dependencies>
<!-- https://mvnrepository.com/artifact/org.apache.avro/avro -->
<dependency>
<groupId>org.apache.avro</groupId>
<artifactId>avro</artifactId>
<version>${avro.version}</version>
</dependency>
</dependencies>
```
Now add the following section at the end before the `</project>` element.
```xml
<build>
<plugins>
<plugin>
<groupId>org.apache.avro</groupId>
<artifactId>avro-maven-plugin</artifactId>
<version>${avro.version}</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>schema</goal>
<goal>protocol</goal>
<goal>idl-protocol</goal>
</goals>
<configuration>
<stringType>String</stringType>
<fieldVisibility>private</fieldVisibility>
<sourceDirectory>${project.basedir}/src/main/avro</sourceDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>io.confluent</groupId>
<artifactId>kafka-schema-registry-maven-plugin</artifactId>
<version>3.2.0</version>
<configuration>
<schemaRegistryUrls>
<param>http://${env.DATAPLATFORM_IP}:8081</param>
</schemaRegistryUrls>
<subjects>
<test-java-avro-topic-value>src/main/avro/Notification-v1.avsc</test-java-avro-topic-value>
</subjects>
</configuration>
<goals>
<goal>register</goal>
<goal>test-compatibility</goal>
</goals>
</plugin>
</plugins>
</build>
```
The first plugin will make sure, that classes are generated based on the Avro schema, whenever a `mvn compile` is executed.
To second plugin will help to register the Avro schema(s) via Maven into the Confluent Schema Registry.
We also have to specify the additional Maven repository, where the plugins can be found. Add the following XML fragement at the end right before the `project` element.
```xml
<pluginRepositories>
<pluginRepository>
<id>confluent</id>
<url>https://packages.confluent.io/maven/</url>
</pluginRepository>
</pluginRepositories>
```
### Create an Avro Schema representing the Avro Message to send
First create a new Folder `avro` under the existing folder **src/main/**.
Create a new File `Notification-v1.avsc` in the folder **src/main/avro** just created above.
Add the following Avro schema to the empty file.
```json
{
"type" : "record",
"namespace" : "com.trivadis.kafkaws.avro.v1",
"name" : "Notification",
"description" : "A simple Notification Event message",
"fields" : [
{ "name" : "id",
"type" : ["long", "null"]
},
{ "name" : "message",
"type" : ["string", "null"]
},
{ "name" : "createdAt",
"type" : {
"type" : "long",
"logicalType" : "timestamp-millis"
}
}
]
}
```
The Maven plugin added above will make sure, that classes are generated based on the Avro schema, whenever a `mvn compile` is executed. Let's exactly do that on the still rather empty project.
```bash
mvn compile
```
After running this command, refresh the project in your IDE and you should see a new folder named `target/generated-sources/avro`. Navigate into this folder and you should see one generated Java class named `Notification`.
### Register the Avro Schema with the registry
Register the schema with the Schema Registry:
For the IP address of the platform the Schema Registry is running on, we refer to an environment variable, which we have to declare.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
Now use the maven command
```bash
mvn schema-registry:register
```
### Publish the artefact to the local Maven repo
Now let's make sure that the project is available as a Maven dependency:
```bash
mvn install
```
## Create the Spring Boot Producer
First we create an test the Producer microservice.
### Creating the Spring Boot Project
First, let’s navigate to [Spring Initializr](https://start.spring.io/) to generate our project. Our project will need the Apache Kafka support.
Select Generate a **Maven Project** with **Kotlin** and Spring Boot **2.7.0**. Enter `com.trivadis.kafkaws` for the **Group**, `spring-boot-kotlin-kafka-producer-avro` for the **Artifact** field and `Kafka Producer with Avro project for Spring Boot` for the **Description** field.
Click on **Add Dependencies** and search for the **Spring for Apache Kafka** depencency.
Select the dependency and hit the **Enter** key. You should now see the dependency on the right side of the screen.
Click on **Generate Project** and unzip the ZIP file to a convenient location for development.
Once you have unzipped the project, you’ll have a very simple structure.
Import the project as a Maven Project into your favourite IDE for further development.
### Extend the Maven POM with some configurations
In oder to use the Avro serializer and the class generated above, we have to add the following dependencies to the `pom.xml`.
```xml
<dependencies>
...
<dependency>
<groupId>com.trivadis.kafkaws.meta</groupId>
<artifactId>meta</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>io.confluent</groupId>
<artifactId>kafka-avro-serializer</artifactId>
<version>${confluent.version}</version>
</dependency>
```
Add the version of the Confluent Platform to use as an additional property
```xml
<properties>
...
<confluent.version>7.0.0</confluent.version>
</properties>
```
We also have to specify the additional Maven repository
```xml
<repositories>
<repository>
<id>confluent</id>
<url>https://packages.confluent.io/maven/</url>
</repository>
</repositories>
```
### Implement a Kafka Producer in Spring
Now create a simple Kotlin class `KafkaEventProducer` within the `com.trivadis.kafkaws.springbootkotlinkafkaproducer ` package, which we will use to produce messages to Kafka.
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaproducer
import com.trivadis.kafkaws.avro.v1.Notification
import org.springframework.beans.factory.annotation.Value
import org.springframework.kafka.core.KafkaTemplate
import org.springframework.kafka.support.SendResult
import org.springframework.stereotype.Component
@Component
class KafkaEventProducer (private val kafkaTemplate: KafkaTemplate<Long, Notification>) {
@Value("\${topic.name}")
private lateinit var kafkaTopic: String
fun produce(key: Long, value: Notification) {
val time = System.currentTimeMillis()
var result: SendResult<Long, Notification>
if (key > 0) {
result = kafkaTemplate.send(kafkaTopic, key, value).get()
} else {
result = kafkaTemplate.send(kafkaTopic, value).get()
}
val elapsedTime = System.currentTimeMillis() - time
println("[$key] sent record(key=$key value=$value) meta(partition=${result.recordMetadata.partition()}, offset=${result.recordMetadata.offset()}) time=$elapsedTime")
}
}
```
We no longer use `String` as type for the value but the `Nofification` class, which has been generated based on the Avro schema above.
### Create the necessary Topics through code
Spring Kafka can automatically add topics to the broker, if they do not yet exists. By that you can replace the `kafka-topics` CLI commands seen so far to create the topics, if you like.
Spring Kafka provides a `TopicBuilder` which makes the creation of the topics very convenient.
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaproducer
import org.apache.kafka.clients.admin.NewTopic
import org.springframework.beans.factory.annotation.Value
import org.springframework.context.annotation.Bean
import org.springframework.kafka.config.TopicBuilder
import org.springframework.stereotype.Component
@Component
class TopicCreator {
@Value("\${topic.name}")
private lateinit var kafkaTopic: String
@Value("\${topic.partitions}")
private var partitions: Int = 0
@Value("\${topic.replication-factor}")
private var replicationFactor: Int = 0
@Bean
fun topic(): NewTopic? {
return TopicBuilder.name(kafkaTopic)
.partitions(partitions)
.replicas(replicationFactor)
.build()
}
}
```
We again refer to properties, which will be defined later in the `application.yml` config file.
### Add Producer logic to the SpringBootKotlinKafkaProducerApplication class
We change the generated Spring Boot application to be a console appliation by implementing the `CommandLineRunner` interface.
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaproducer
import com.trivadis.kafkaws.avro.v1.Notification
import org.springframework.boot.CommandLineRunner
import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication
import org.springframework.context.annotation.Bean
import java.time.Instant
import java.time.LocalDateTime
@SpringBootApplication
class SpringBootKotlinKafkaProducerApplication{
@Bean
fun init(kafkaEventProducer: KafkaEventProducer) = CommandLineRunner { args ->
val sendMessageCount = if (args.size==0) 100 else args[0].toInt()
val waitMsInBetween = if (args.size==0) 10 else args[1].toLong()
val id = if (args.size==0) 0 else args[2].toLong()
for (index in 1 .. sendMessageCount) {
val value = Notification.newBuilder()
.setId(id)
.setMessage("[$id" + "] Hello Kafka " + index + " => " + LocalDateTime.now())
.setCreatedAt(Instant.now())
.build()
kafkaEventProducer.produce(id, value);
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
fun main(args: Array<String>) {
runApplication<SpringBootKotlinKafkaProducerApplication>(*args)
}
```
The difference here to the non-avro version is, that we are using the builder of the generated `Nofification` class to create an instance of a notification, which we then pass as the value to the `produce()` method.
### Configure Kafka through application.yml configuration file
First let's rename the existing `application.properties` file to `application.yml` to use the `yml` format.
Add the following settings to configure the Kafka cluster and the name of the topic:
```yml
topic:
name: test-kotlin-spring-avro-topic
replication-factor: 3
partitions: 12
spring:
kafka:
bootstrap-servers:
- ${DATAPLATFORM_IP}:9092
- ${DATAPLATFORM_IP}:9093
producer:
key-serializer: org.apache.kafka.common.serialization.LongSerializer
value-serializer: io.confluent.kafka.serializers.KafkaAvroSerializer
properties:
auto.register.schemas: false
use.latest.version: true
properties:
schema.registry.url: http://${DATAPLATFORM_IP}:8081
logging:
level:
root: info
```
Here again we swith the value-serializer from `StringSerializer` to the `KafkaAvroSerializer` and add the property `schema.registry.url` to configure the location of the Confluent Schema Registry REST API.
For the IP address of the Kafka cluster we refer to an environment variable, which we have to declare before running the application.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
### Build the application
First lets build the application:
```bash
mvn package -Dmaven.test.skip=true
```
### Run the application
Now let's run the application
```bash
mvn spring-boot:run
```
Make sure that you see the messages through the console consumer.
To run the producer with custom parameters (for example to specify the key to use), use the `-Dspring-boot.run.arguments`:
```bash
mvn spring-boot:run -Dspring-boot.run.arguments="100 10 10"
```
### Use Console to test the application
In a terminal window start consuming from the output topic:
```bash
kcat -b kafka-1:19092 -t test-kotlin-spring-avro-topic -s value=avro -r http://schema-registry-1:8081
```
## Create the Spring Boot Consumer
Now let's create an test the Consumer microservice.
### Creating the Spring Boot Project
Use again the [Spring Initializr](https://start.spring.io/) to generate the project.
Select Generate a **Maven Project** with **Kotlin** and Spring Boot **2.7.0**. Enter `com.trivadis.kafkaws` for the **Group**, `spring-boot-kotlin-kafka-consumer-avro` for the **Artifact** field and `Kafka Consumer with Avro project for Spring Boot` for the **Description** field.
Click on **Add Dependencies** and search for the **Spring for Apache Kafka** depencency.
Select the dependency and hit the **Enter** key. You should now see the dependency on the right side of the screen.
Click on **Generate Project** and unzip the ZIP file to a convenient location for development.
Once you have unzipped the project, you’ll have a very simple structure.
Import the project as a Maven Project into your favourite IDE for further development.
### Extend the Maven POM with some configurations
In oder to use the Avro deserializer and the Avro generated classes, we have to add the following dependencies to the `pom.xml`.
```xml
<dependencies>
...
<dependency>
<groupId>io.confluent</groupId>
<artifactId>kafka-avro-serializer</artifactId>
<version>${confluent.version}</version>
</dependency>
<dependency>
<groupId>com.trivadis.kafkaws.meta</groupId>
<artifactId>meta</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
```
Add the version of the Confluent Platform to use as an additional property
```xml
<properties>
...
<confluent.version>7.0.0</confluent.version>
</properties>
```
We also have to specify the additional Maven repository
```xml
<repositories>
<repository>
<id>confluent</id>
<url>https://packages.confluent.io/maven/</url>
</repository>
</repositories>
```
### Implement a Kafka Consumer in Spring
Start by creating a simple Kotlin class `KafkaEventConsumer` within the `com.trivadis.kafkaws.springbootkafkaconsumer` package, which we will use to consume messages from Kafka.
```kotlin
package com.trivadis.kafkaws.springbootkotlinkafkaconsumer
import com.trivadis.kafkaws.avro.v1.Notification
import org.apache.kafka.clients.consumer.ConsumerRecord
import org.springframework.kafka.annotation.KafkaListener
import org.springframework.stereotype.Component
@Component
class KafkaEventConsumer {
@KafkaListener(topics = ["\${topic.name}"], groupId = "simple-kotlin-avro-consumer")
fun receive(consumerRecord: ConsumerRecord<Long, Notification>) {
println("received key = ${consumerRecord.key()} with payload=${consumerRecord.value()}")
}
}
```
This class uses the `Component` annotation to have it registered as bean in the Spring context and the `KafkaListener` annotation to specify a listener method to be called for each record consumed from the Kafka input topic. The name of the topic is specified as a property to be read again from the `application.yml` configuration file.
In the code we only log the key and value received to the console. In real life, we would probably inject another bean into the `KafkaEventConsumer` to perform the message processing.
### Configure Kafka through application.yml configuration file
First let's rename the existing `application.properties` file to `application.yml` to use the `yml` format.
Add the following settings to configure the Kafka cluster and the name of the two topics:
```yml
topic:
name: test-kotlin-spring-avro-topic
spring:
kafka:
bootstrap-servers:
- ${DATAPLATFORM_IP}:9092
- ${DATAPLATFORM_IP}:9093
consumer:
key-deserializer: org.apache.kafka.common.serialization.LongDeserializer
value-deserializer: io.confluent.kafka.serializers.KafkaAvroDeserializer
properties:
auto.register.schemas: false
specific.avro.reader: true
properties:
schema.registry.url: http://${DATAPLATFORM_IP}:8081
logging:
level:
root: info
```
For the IP address of the Kafka cluster we refer to an environment variable, which we have to declare before running the application.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
### Build the application
First lets build the application:
```bash
mvn package -Dmaven.test.skip=true
```
### Run the application
Now let's run the application
```bash
mvn spring-boot:run
```

}<file_sep># Using Kafka from Java with Avro IDL & Schema Registry
In this workshop we will learn how to produce and consume messages using the [Kafka Java API](https://kafka.apache.org/documentation/#api) using Avro for serialising and deserialising messages.
Compared to workshop 4a, here we will use the [Avro IDL language](https://avro.apache.org/docs/current/idl-language/) for defining the Avro Schema. The advantage of using the Avro IDL language is first better readability when a schema get's more complex, better [IDE support](https://avro.apache.org/docs/current/idl-language/#ide-support) and the possibility for importing schema definitions from another file.
But for the Schema Registry, we will still need the schemas in the JSON language, but the can be generated from the IDL (using Avro Tools).
## Create the project in your Java IDE
Create a new Maven Project (using the functionality of your IDE) and in the last step use `com.trivadis.kafkaws` for the **Group Id** and `java-avro-idl-kafka` for the **Artifact Id**.
Navigate to the **pom.xml** and double-click on it. The POM Editor will be displayed.
You can either use the GUI to edit your `pom.xml` or navigate to the last tab **pom.xml** to switch to the "code view". Let's do that.
You will see the still rather empty definition.
```xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.trivadis.kafkaws</groupId>
<artifactId>java-avro-idl-kafka</artifactId>
<version>0.0.1-SNAPSHOT</version>
</project>
```
Let's add some initial dependencies for our project. We will add some more dependencies to the POM throughout this workshop.
Copy the following block right after the `<version>` tag, before the closing `</project>` tag.
```xml

```
The `pom.xml` is the same as for workshop 4a, except the additional maven plugin `avdl2avsc-maven-plugin`, which we can get from the Maven Repo hosted on GitHub.
This plugin will be used to generate the Avro JSON Schema definition from the IDL. It wraps the necessary functionality of the Avro tools library.
Additionally we changed the `sourceDirectory` of the `avro-maven-plugin` to reflect the directory where we will place the Avro IDL schemas (`${project.basedir}/src/main/avdl`).
## Create log4j settings
Let's also create the necessary log4j configuration.
In the code we are using the [Log4J Logging Framework](https://logging.apache.org/log4j/2.x/), which we have to configure using a property file.
Create a new file `log4j.properties` in the folder **src/main/resources** and add the following configuration properties.
```

```
## Creating the necessary Kafka Topic
We will use the topic `test-java-avro-idl-topic` in the Producer and Consumer code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
In a terminal window, connect to the `kafka-1` container
```
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```
kafka-topics --create \
--replication-factor 3 \
--partitions 12 \
--topic test-java-avro-idl-topic \
--bootstrap-server kafka-1:19092,kafka-2:19093
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing the **Kafka Producer** which uses Avro for the serialisation.
## Create an Avro Schema representing the Notification Message
First create a new Folder `avdl` under the existing folder **src/main/**.
Create a new File `Notification.avdl` in the folder **src/main/avdl** just created above.
Add the following Avro schema to the empty file, using the Avro IDL language.
```
@namespace("com.trivadis.kafkaws.avro.v1")
protocol NotificationProtocol {
record Notification {
union {null, long} id;
union {null, string} message;
}
}
```
This represent the Notification object.
We will use another schema to define the `NotificationSentEvent` event and import the `Notification` object. Create a new file `NotificationSentEvent-v1.avdl` in the `avdl` folder and add the folllowing schema defintion:
```
@namespace("com.trivadis.kafkaws.avro.v1")
protocol NotificationSentEventProtocol {
import idl "Notification.avdl";
record NotificationSentEvent {
Notification notification;
}
}
```
Let's now run a Maven compile to generate both the Avro JSON schema as well as the Java code for the Avro Serialization/Deserialization.
```
mvn compile
```
After running this command, refresh the project and you should see a new folder named `target/generated-sources/avro`. Expand into this folder and you should see both the generated Java classes as well as a `schema` folder with the two `avsc` schemas. We get two classes for each IDL file, one for the `protocol` and one for the `record`, although we will only use the one for the `record` definitions, `Notification.java` and `NotificationSentEvent.java`.
Double click on the `Notification.avsc` file to inspect the Avro schema in JSON.
```json
{
"type" : "record",
"name" : "Notification",
"namespace" : "com.trivadis.kafkaws.avro.v1",
"fields" : [ {
"name" : "id",
"type" : [ "null", "long" ]
}, {
"name" : "message",
"type" : [ "null", "string" ]
} ]
}
```
and let's inspect also the `NotificationSentEvent.avsc`
```json
{
"type" : "record",
"name" : "NotificationSentEvent",
"namespace" : "com.trivadis.kafkaws.avro.v1",
"fields" : [ {
"name" : "notification",
"type" : {
"type" : "record",
"name" : "Notification",
"fields" : [ {
"name" : "id",
"type" : [ "null", "long" ]
}, {
"name" : "message",
"type" : [ "null", "string" ]
} ]
}
} ]
}
```
You can see that `NotificationSentEvent.avsc` embeds the definition of the `Notification`, due to the import we did.
## Create a Kafka Producer using Avro for serialisation
First create a new Java Package `com.trivadis.kafkaws.producer` in the folder **src/main/java**.
Create a new Java Class `KafkaProducerAvro` in the package `com.trivadis.kafakws.producer` just created.
Add the following code to the empty class to create a Kafka Producer. It is similar to the code we have seen in the workshop 4a, except that we now use the `NotificationSentEvent` class and we produce to a different topic (`test-java-avro-idl-topic`).
```java
package com.trivadis.kafkaws.producer;
import java.util.Properties;
import com.trivadis.kafkaws.avro.v1.Notification;
import com.trivadis.kafkaws.avro.v1.NotificationSentEvent;
import org.apache.kafka.clients.producer.*;
import org.apache.kafka.common.serialization.LongSerializer;
import org.apache.kafka.common.serialization.StringSerializer;
import io.confluent.kafka.serializers.KafkaAvroSerializer;
import io.confluent.kafka.serializers.KafkaAvroSerializerConfig;
public class KafkaProducerAvro {
private final static String TOPIC = "test-java-avro-idl-topic";
private final static String BOOTSTRAP_SERVERS =
"dataplatform:9092, dataplatform:9093, dataplatform:9094";
private final static String SCHEMA_REGISTRY_URL = "http://dataplatform:8081";
private static Producer<Long, NotificationSentEvent> createProducer() {
Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ProducerConfig.CLIENT_ID_CONFIG, "KafkaExampleProducer");
//props.put(KafkaAvroSerializerConfig.AUTO_REGISTER_SCHEMAS, "false");
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, KafkaAvroSerializer.class.getName());
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, KafkaAvroSerializer.class.getName());
props.put(KafkaAvroSerializerConfig.SCHEMA_REGISTRY_URL_CONFIG, SCHEMA_REGISTRY_URL); // use constant for "schema.registry.url"
return new KafkaProducer<>(props);
}
static void runProducer(final int sendMessageCount, final int waitMsInBetween, final long id) throws Exception {
final Producer<Long, NotificationSentEvent> producer = createProducer();
long time = System.currentTimeMillis();
Long key = (id > 0) ? id : null;
try {
for (long index = 0; index < sendMessageCount; index++) {
NotificationSentEvent notification = NotificationSentEvent.newBuilder()
.setNotification(Notification.newBuilder()
.setId(id)
.setMessage("Hello Kafka " + index)
.build())
.build();
final ProducerRecord<Long, NotificationSentEvent> record =
new ProducerRecord<>(TOPIC, key, notification);
RecordMetadata metadata = producer.send(record).get();
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) " +
"meta(partition=%d, offset=%d) time=%d\n",
record.key(), record.value(), metadata.partition(),
metadata.offset(), elapsedTime);
time = System.currentTimeMillis();
Thread.sleep(waitMsInBetween);
}
} finally {
producer.flush();
producer.close();
}
}
public static void main(String... args) throws Exception {
if (args.length == 0) {
runProducer(100,10,0);
} else {
runProducer(Integer.parseInt(args[0]),Integer.parseInt(args[1]),Long.parseLong(args[2]));
}
}
}
```
We will be are using the synchronous way for producing messages to the Kafka topic but the other methods would work as well.
The `main()` method accepts 3 parameters, the number of messages to produce, the time in ms to wait in-between sending each message and the ID of the producer.
Use `kcat` or `kafka-console-consumer` to consume the messages from the topic `test-java-avro-idl-topic `.
```bash
kcat -b kafka-1:19092 -t test-java-avro-idl-topic -s value=avro -r http://schema-registry-1:8081
```
Now run it using the `mvn exec:java` command. It will generate 1000 messages, waiting 10ms in-between sending each message and use 0 for the ID.
```
mvn exec:java@producer -Dexec.args="1000 10 0"
```
**Note:** if your maven version does not support profiles, then you have to specify the main class as well: `mvn exec:java -Dexec.mainClass="com.trivadis.kafkaws.producer.KafkaProducerSync" -Dexec.args="1000 100 0"`
In a browser, navigate to <http://dataplatform:28039> and you should see the home page of the Schema Registry UI. Le's make sure that the schema has been registered automatically.
## Create a Kafka Consumer using Avro for serialization
First create a new Java Package `com.trivadis.kafkaws.consumer` in the folder **src/main/java**.
Create a new Java Class `KafkaConsumerAvro` in the package `com.trivadis.kafakws.consumer` just created.
Add the following code to the empty class.
```java
package com.trivadis.kafkaws.consumer;
import java.time.Duration;
import java.util.Collections;
import java.util.Properties;
import com.trivadis.kafkaws.avro.v1.NotificationSentEvent;
import org.apache.kafka.clients.consumer.Consumer;
import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.KafkaConsumer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.common.serialization.LongDeserializer;
import org.apache.kafka.common.serialization.StringDeserializer;
import com.trivadis.kafkaws.avro.v1.Notification;
import io.confluent.kafka.serializers.KafkaAvroDeserializer;
import io.confluent.kafka.serializers.KafkaAvroSerializer;
import io.confluent.kafka.serializers.KafkaAvroSerializerConfig;
public class KafkaConsumerAvro {
private final static String TOPIC = "test-java-avro-idl-topic";
private final static String BOOTSTRAP_SERVERS =
"dataplatform:9092, dataplatform:9093, dataplatform:9094";
private final static String SCHEMA_REGISTRY_URL = "http://dataplatform:8081";
private static Consumer<Long, NotificationSentEvent> createConsumer() {
final Properties props = new Properties();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS);
props.put(ConsumerConfig.GROUP_ID_CONFIG, "KafkaConsumerAvro");
props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, false);
props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, 10000);
props.put(KafkaAvroSerializerConfig.AUTO_REGISTER_SCHEMAS, "false");
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, KafkaAvroDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, KafkaAvroDeserializer.class.getName());
props.put(KafkaAvroSerializerConfig.SCHEMA_REGISTRY_URL_CONFIG, SCHEMA_REGISTRY_URL); // use constant for "schema.registry.url"
// Create the consumer using props.
final Consumer<Long, NotificationSentEvent> consumer =
new KafkaConsumer<>(props);
// Subscribe to the topic.
consumer.subscribe(Collections.singletonList(TOPIC));
return consumer;
}
static void runConsumer(int waitMsInBetween) throws InterruptedException {
final Consumer<Long, NotificationSentEvent> consumer = createConsumer();
final int giveUp = 100;
int noRecordsCount = 0;
while (true) {
final ConsumerRecords<Long, NotificationSentEvent> consumerRecords = consumer.poll(Duration.ofMillis(1000));
if (consumerRecords.count()==0) {
noRecordsCount++;
if (noRecordsCount > giveUp)
break;
}
consumerRecords.forEach(record -> {
System.out.printf("%d - Consumer Record:(Key: %d, Value: %s, Partition: %d, Offset: %d)\n",
consumerRecords.count(), record.key(), record.value(),
record.partition(), record.offset());
try {
Thread.sleep(waitMsInBetween);
} catch (InterruptedException e) {
}
});
consumer.commitSync();
}
consumer.close();
System.out.println("DONE");
}
public static void main(String... args) throws Exception {
if (args.length == 0) {
runConsumer(10);
} else {
runConsumer(Integer.parseInt(args[0]));
}
}
}
```
## Register in Schema Registry using Maven
In the test above, the Avro schema has been registered in the schema registry when starting the Producer for the first time. To register an Avro schema through Maven automatically, you can again use the `kafka-schema-registry-maven-plugin ` Maven plugin.
Add the following definition to the `pom.xml`.
```xml
<plugin>
<groupId>io.confluent</groupId>
<artifactId>kafka-schema-registry-maven-plugin</artifactId>
<version>6.2.0</version>
<configuration>
<schemaRegistryUrls>
<param>http://${DATAPLATFORM_IP}:8081</param>
</schemaRegistryUrls>
<subjects>
<test-java-avro-idl-topic-value>target/generated-sources/avro/schema/NotificationSentEvent.avsc</test-java-avro-idl-topic-value>
</subjects>
</configuration>
<goals>
<goal>register</goal>
<goal>test-compatibility</goal>
</goals>
</plugin>
```
Note that we now have to get the Avro schema (Json syntax) from the `target/generated-sources` folder.
Now you can use the following command to register the schemas with the Schema Registry:
```
mvn schema-registry:register
```
## Adding documentation to the Avro IDL
The Avro IDL language also [supports comments](https://avro.apache.org/docs/1.11.1/idl-language/#comments).
All Java-style comments are supported within a Avro IDL file. Any text following `//` on a line is ignored, as is any text between `/*` and `*/`, possibly spanning multiple lines.
Comments that begin with `/**` are used as the documentation string for the type or field definition that follows the comment
Let's extend `Notification.avdl` with some comments on record as well as on field level:
```
@namespace("com.trivadis.kafkaws.avro.v1")
protocol NotificationProtocol {
/**
Notification structure defining a message to be sent as a notification.
Will be used to notify users of a problem.
*/
record Notification {
/**
This is the ID of a notification, optional
*/
union {null, long} id; // optional, should be changed in the future to mandatory!
/** This is the message of the notification */
union {null, string} message;
}
}
```
The same can be done on the `NotificationSentEvent.avdl`:
```
@namespace("com.trivadis.kafkaws.avro.v1")
protocol NotificationSentEventProtocol {
import idl "Notification.avdl";
/**
This is the Notification Event structure which uses an embedded Notification object.
*/
record NotificationSentEvent {
/** the Notification embedded object */
Notification notification;
}
}
```
Not let's regenerate the code
```bash
mvn compile
```
and we will find the comments also in the generated Java classes, here showing parts of the `Notification` class as an example:
```java
/** Notification structure defining a message to be sent as a notification.
Will be used to notify users of a problem. */
@org.apache.avro.specific.AvroGenerated
public class Notification extends org.apache.avro.specific.SpecificRecordBase implements org.apache.avro.specific.SpecificRecord {
private static final long serialVersionUID = 3582798745986381455L;
...
/** This is the ID of a notification, optional */
private java.lang.Long id;
/** This is the message of the notification */
private java.lang.String message;
...
/**
* Gets the value of the 'id' field.
* @return This is the ID of a notification, optional
*/
public java.lang.Long getId() {
return id;
}
/**
* Sets the value of the 'id' field.
* This is the ID of a notification, optional
* @param value the value to set.
*/
public void setId(java.lang.Long value) {
this.id = value;
}
```
## Adding deprecation to Avro IDL
Let's say we in the process of replacing an existing field in Avro with a new field. In order to be compatible, we need to support the old field for some time in parallel to the new field.
But of course we would like to notify all the users of the deprecation of the field. That's where the `@deprecated` comment can be used, as shown below. Let's say we replace the single string-typed `message` field with an array-typed `messages` field. We can deprecate the `message` field by adding `@deprecated` to the documentation together with a deprecation note:
```
@namespace("com.trivadis.kafkaws.avro.v1")
protocol NotificationProtocol {
/**
Notification structure defining a message to be sent as a notification.
Will be used to notify users of a problem.
deprecated
*/
record Notification {
/**
This is the ID of a notification, optional
*/
union {null, long} @javaAnnotation("Deprecated") id; // optional, should be changed in the future to mandatory!
/** This is the message of the notification
@deprecated use the new array-based "messages" field instead
*/
union {null, string} message;
/** This are the messages of the notification
*/
union {null, array<string>} messages;
}
}
```
The `@deprecated` comment will end up in the generated Java class both in the property definition as well as in the getter and setter methods:
```java
@org.apache.avro.specific.AvroGenerated
public class Notification extends org.apache.avro.specific.SpecificRecordBase implements org.apache.avro.specific.SpecificRecord {
private static final long serialVersionUID = 2885908480528460301L;
...
/** This is the message of the notification
@deprecated use messages instead */
private java.lang.String message;
...
/**
* Gets the value of the 'message' field.
* @return This is the message of the notification
@deprecated use the new array-based "messages" field instead
*/
public java.lang.String getMessage() {
return message;
}
/**
* Sets the value of the 'message' field.
* This is the message of the notification
@deprecated use the new array-based "messages" field instead
* @param value the value to set.
*/
public void setMessage(java.lang.String value) {
this.message = value;
}
...
```
if you now run
```bash
mvn clean compile -Dmaven.compiler.showWarnings=true -Dmaven.compiler.showWarnings=true
```
to compile the source code, you will see the deprecation warning for usage of the old field.
```bash
[INFO] --- maven-compiler-plugin:2.5:compile (default-compile) @ java-kafka-avro-idl ---
[INFO] Compiling 6 source files to /Users/guido.schmutz/Documents/GitHub/gschmutz/kafka-workshop/04b-working-with-avro-idl-and-java/src/java-kafka-avro-idl/target/classes
[WARNING] bootstrap class path not set in conjunction with -source 8
/Users/guido.schmutz/Documents/GitHub/gschmutz/kafka-workshop/04b-working-with-avro-idl-and-java/src/java-kafka-avro-idl/src/main/java/com/trivadis/kafkaws/producer/KafkaProducerAvro.java:[43,24] [deprecation] setMessage(String) in Builder has been deprecated
```
In our case it's in the `KafkaProducerAvro` class.
Depending on the IDE used, the usage will also nicely flagged visually. Bellow how it is shown in IntelliJ

In this workshop we will learn how to use the [confluent-kafka-go](https://github.com/confluentinc/confluent-kafka-go) to produce and consume to/from Kafka from the Go language.
You can find many examples of using Kafka with Go [here](https://github.com/confluentinc/confluent-kafka-go/tree/master/examples) in the GitHub project.
This guide assumes that you already have the Go language tools installed.
## Setup
### Creating the necessary Kafka Topic
We will use the topic `test-node-topic` in the Producer and Consumer code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
Connect to the `kafka-1` container
```
docker exec -ti kafka-1 bash
```
and execute the necessary kafka-topics command.
```
kafka-topics --create \
--replication-factor 3 \
--partitions 8 \
--topic test-golang-topic \
--bootstrap-server kafka-1:19092
```
Cross check that the topic has been created.
```
kafka-topics --list \
--bootstrap-server kafka-1:19092
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing the **Kafka Producer** which uses Avro for the serialisation.
## Create a Go Project
Create a new directory anywhere you’d like for this project:
```bash
mkdir golang-kafka && cd golang-kafka
```
Initialize the Go module and download the Confluent Go Kafka dependency:
```
go mod init golang-kafka
go get github.com/confluentinc/confluent-kafka-go/kafka
```
# Create Kafka Producer
Next we are going to create the producer application by pasting the following Go code into a file named `producer.go`.
```go
package main
import (
"fmt"
"strconv"
"github.com/confluentinc/confluent-kafka-go/kafka"
"os"
"time"
)
func main() {
sendMessageCount, err := strconv.Atoi(os.Args[1])
waitMsInBetween, err := strconv.Atoi(os.Args[2])
id, err := strconv.Atoi(os.Args[3])
p, err := kafka.NewProducer(&kafka.ConfigMap{"bootstrap.servers": "dataplatform:9092",
"acks": "all"})
if err != nil {
fmt.Printf("Failed to create producer: %s\n", err)
os.Exit(1)
}
fmt.Printf("Created Producer %v\n", p)
// Listen to all the events on the default events channel
go func() {
for e := range p.Events() {
switch ev := e.(type) {
case *kafka.Message:
// The message delivery report, indicating success or
// permanent failure after retries have been exhausted.
// Application level retries won't help since the client
// is already configured to do that.
m := ev
if m.TopicPartition.Error != nil {
fmt.Printf("Delivery failed: %v\n", m.TopicPartition.Error)
} else {
fmt.Printf("Delivered message to topic %s [%d] at offset %v\n",
*m.TopicPartition.Topic, m.TopicPartition.Partition, m.TopicPartition.Offset)
}
case kafka.Error:
// Generic client instance-level errors, such as
// broker connection failures, authentication issues, etc.
//
// These errors should generally be considered informational
// as the underlying client will automatically try to
// recover from any errors encountered, the application
// does not need to take action on them.
fmt.Printf("Error: %v\n", ev)
default:
fmt.Printf("Ignored event: %s\n", ev)
}
}
}()
topic := "test-golang-topic"
for i := 1; i <= sendMessageCount; i++ {
value := fmt.Sprintf("[%d] Hello Kafka #%d => %s", i, i, time.Now().Format(time.RFC3339))
if id == 0 {
err = p.Produce(&kafka.Message{
TopicPartition: kafka.TopicPartition{Topic: &topic, Partition: kafka.PartitionAny},
Value: []byte(value),
Headers: []kafka.Header{{Key: "myTestHeader", Value: []byte("header values are binary")}},
}, nil)
} else {
err = p.Produce(&kafka.Message{
TopicPartition: kafka.TopicPartition{Topic: &topic, Partition: kafka.PartitionAny},
Key: []byte(strconv.Itoa(id)),
Value: []byte(value),
Headers: []kafka.Header{{Key: "myTestHeader", Value: []byte("header values are binary")}},
}, nil)
}
if err != nil {
if err.(kafka.Error).Code() == kafka.ErrQueueFull {
// Producer queue is full, wait 1s for messages
// to be delivered then try again.
time.Sleep(time.Second)
continue
}
fmt.Printf("Failed to produce message: %v\n", err)
}
// Slow down processing
time.Sleep(time.Duration(waitMsInBetween) * time.Millisecond)
}
// Flush and close the producer and the events channel
for p.Flush(10000) > 0 {
fmt.Print("Still waiting to flush outstanding messages\n", err)
}
p.Close()
}
```
# Kafka Consumer
Next let's create the consumer by pasting the following code into a file named `consumer.go`.
```go
package main
import (
"fmt"
"github.com/confluentinc/confluent-kafka-go/kafka"
"os"
"os/signal"
"strconv"
"syscall"
"time"
)
func main() {
if len(os.Args) < 1 {
fmt.Fprintf(os.Stderr, "Usage: %s <wait-ms-in-between>\n",
os.Args[0])
os.Exit(1)
}
waitMsInBetween, err := strconv.Atoi(os.Args[1])
sigchan := make(chan os.Signal, 1)
signal.Notify(sigchan, syscall.SIGINT, syscall.SIGTERM)
c, err := kafka.NewConsumer(&kafka.ConfigMap{
"bootstrap.servers": "dataplatform:9092",
// Avoid connecting to IPv6 brokers:
// This is needed for the ErrAllBrokersDown show-case below
// when using localhost brokers on OSX, since the OSX resolver
// will return the IPv6 addresses first.
// You typically don't need to specify this configuration property.
"broker.address.family": "v4",
"group.id": "GoConsumer",
"session.timeout.ms": 6000,
"auto.offset.reset": "earliest",
"enable.auto.offset.store": false,
})
if err != nil {
fmt.Fprintf(os.Stderr, "Failed to create consumer: %s\n", err)
os.Exit(1)
}
fmt.Printf("Created Consumer %v\n", c)
topics := []string{"test-golang-topic"}
err = c.SubscribeTopics(topics, nil)
run := true
for run {
select {
case sig := <-sigchan:
fmt.Printf("Caught signal %v: terminating\n", sig)
run = false
default:
ev := c.Poll(100)
if ev == nil {
continue
}
switch e := ev.(type) {
case *kafka.Message:
fmt.Printf("%% Message on %s:\n%s\n",
e.TopicPartition, string(e.Value))
if e.Headers != nil {
fmt.Printf("%% Headers: %v\n", e.Headers)
}
_, err := c.StoreMessage(e)
if err != nil {
fmt.Fprintf(os.Stderr, "%% Error storing offset after message %s:\n",
e.TopicPartition)
}
case kafka.Error:
// Errors should generally be considered
// informational, the client will try to
// automatically recover.
// But in this example we choose to terminate
// the application if all brokers are down.
fmt.Fprintf(os.Stderr, "%% Error: %v: %v\n", e.Code(), e)
if e.Code() == kafka.ErrAllBrokersDown {
run = false
}
default:
fmt.Printf("Ignored %v\n", e)
}
// Slow down processing
time.Sleep(time.Duration(waitMsInBetween) * time.Millisecond)
}
}
fmt.Printf("Closing consumer\n")
c.Close()
}
```

<file_sep># What to do when the Public IP address has been changed?
This short instruction shows what to do when you have a running Platys stack and the Public IP address of the Docker host has been changed (this can happen if your docker host is running in a cloud VM).
Some services of platys will no longer run correctly, if the IP address changes, therefore the stack has to be stopped and removed and then started again. Therefore you should **try to avoid a change of the IP address**, i.e. in the cloud by assigning a stack IP address!
You can check what your IP was when running the stack by showing the value of the PUBLIC_IP variable
```
echo $PUBLIC_IP
```
In the code blocks below we assume that the `DATAPLATFORM_HOME` variable is set and points to the `docker` folder where the metadata on the docker compose stack is located (the folder holding the `docker-compose.yml` file).
Navigate into the stack and stop and remove all the services. Be aware that all the data inside your running container will be removed!
```
cd $DATAPLATFORM_HOME
docker-compose down
```
Change the environment variables to hold the new IP address
```
export PUBLIC_IP=$(curl ipinfo.io/ip)
export DOCKER_HOST_IP=$(ip addr show ${NETWORK_NAME} | grep "inet\b" | awk '{print $2}' | cut -d/ -f1)
```
Check that the value of the variable is the correct IP address
```
echo $PUBLIC_IP
```
Update the `.bash_profile` script to relect the new IP address (so that after a new login it will be correct).
Open the file with an editor (change the username variable to your current user)
```
export USERNAME=ubuntu
nano /home/$USERNAME/.bash_profile
```
Save the file with **Ctrl-O** and exit with **Ctrl-X**.
Restart the stack
```
cd $DATAPLATFORM_HOME
docker-compose up -d
```
Check the log files
```
docker-compse logs -f
```

<file_sep># Kafka from Spring Boot using Cloud Stream with Avro & Schema Registry
In this workshop we will learn how to use the **Spring Cloud Stream** with Avro message serialization from within a Spring Boot application. We will implement both a consumer and a producer. We are using the same Avro schema and reuse the `meta` project from [Workshop 5a: Kafka from Spring Boot with Avro & Schema Registry](../05a-working-with-avro-and-springboot).
We will create two Spring Boot projects, one for the Producer and one for the Consumer, simulating two independent microservices interacting with eachother via events.
Before you can go further, make sure to create and build the [meta](https://github.com/gschmutz/kafka-workshop/tree/master/05a-working-with-avro-and-springboot#create-the-avro-metadata-project) project as demonstrated in [Workshop 5a: Kafka from Spring Boot with Avro & Schema Registry](../05a-working-with-avro-and-springboot).
## Create the Spring Boot Producer Project
First we create an test the Producer microservice using Spring Cloud Stream abstraction.
### Creating the Spring Boot Project
First, let’s navigate to [Spring Initializr](https://start.spring.io/) to generate our project. Our project will need the Spring Cloud Stream support.
Select Generate a **Maven Project** with **Java** and Spring Boot **2.6.5**. Enter `com.trivadis.kafkaws` for the **Group**, `spring-boot-cloud-stream-kafka-producer-avro` for the **Artifact** field and `Kafka Producer with Avro project for Spring Cloud Stream` for the **Description** field.
Click on **Add Dependencies** and search for the **Spring Cloud Stream** depencency.
Select the dependency and hit the **Enter** key. You should now see the dependency on the right side of the screen.
Click on **Generate Project** and unzip the ZIP file to a convenient location for development.
Once you have unzipped the project, you’ll have a very simple structure.
Import the project as a Maven Project into your favourite IDE for further development.
### Extend the Maven POM with some configurations
In oder to use the Avro serializer and the class generated above, we have to add the following dependencies to the `pom.xml`.
```xml
<dependencies>
...
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream-binder-kafka</artifactId>
</dependency>
<dependency>
<groupId>io.confluent</groupId>
<artifactId>kafka-avro-serializer</artifactId>
<version>${confluent.version}</version> <exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>io.confluent</groupId>
<artifactId>kafka-schema-registry-client</artifactId>
<version>${confluent.version}</version>
</dependency>
<dependency>
<groupId>com.trivadis.kafkaws.meta</groupId>
<artifactId>meta</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
```
Add the version of the Confluent Platform to use as an additional property
```xml
<properties>
...
<confluent.version>7.0.0</confluent.version>
</properties>
```
We also have to specify the additional Maven repository
```xml
<repositories>
<repository>
<id>confluent</id>
<url>https://packages.confluent.io/maven/</url>
</repository>
</repositories>
```
### Implement a Kafka Producer in Spring
Now create a simple Java class `KafkaEventProducer` within the `com.trivadis.kafkaws.springbootkafkaproducer ` package, which we will use to produce messages to Kafka.
```java
package com.trivadis.kafkaws.springcloudstreamkafkaproducer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.stream.messaging.Processor;
import org.springframework.kafka.support.KafkaHeaders;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Service;
@Service
public class KafkaEventProducer {
private static final Logger LOGGER = LoggerFactory.getLogger(KafkaEventProducer.class);
@Autowired
private Processor processor;
@Value("${topic.name}")
String kafkaTopic;
public void produce(Integer id, Long key, String value) {
long time = System.currentTimeMillis();
Message<String> message = MessageBuilder.withPayload(value)
.setHeader(KafkaHeaders.MESSAGE_KEY, key)
.build();
processor.output()
.send(message);
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) time=%d\n",key, value,elapsedTime);
}
}
```
We no longer use `String` as type for the value but the `Nofification` class, which has been generated based on the Avro schema above.
### Create the necessary Topics through code
Spring Kafka can automatically add topics to the broker, if they do not yet exists. By that you can replace the `kafka-topics` CLI commands seen so far to create the topics, if you like. This code is exactly the same as in workshop 4 with the non-avro version.
```java
package com.trivadis.kafkaws.springcloudstreamkafkaproduceravro;
import com.trivadis.kafkaws.avro.v1.Notification;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.stream.messaging.Processor;
import org.springframework.kafka.support.KafkaHeaders;
import org.springframework.messaging.Message;
import org.springframework.messaging.support.MessageBuilder;
import org.springframework.stereotype.Component;
@Component
public class KafkaEventProducer {
private static final Logger LOGGER = LoggerFactory.getLogger(KafkaEventProducer.class);
@Autowired
private Processor processor;
@Value("${topic.name}")
String kafkaTopic;
public void produce(Integer id, Long key, Notification notification) {
long time = System.currentTimeMillis();
Message<Notification> message = MessageBuilder.withPayload(notification)
.setHeader(KafkaHeaders.MESSAGE_KEY, key)
.build();
processor.output()
.send(message);
long elapsedTime = System.currentTimeMillis() - time;
System.out.printf("[" + id + "] sent record(key=%s value=%s) time=%d\n",key, notification,elapsedTime);
}
}
```
We again refer to properties, which will be defined later in the `application.yml` config file.
### Add Producer logic to the SpringCloudStreamKafkaProducerAvroApplication class
We change the generated Spring Boot application to be a console appliation by implementing the `CommandLineRunner` interface. The `run` method holds the same code as the `main()` method in [Workshop 4: Working with Kafka from Java](../04-producing-consuming-kafka-with-java). The `runProducer` method is also similar, we just use the `kafkaEventProducer` instance injected by Spring to produce the messages to Kafka.
```java
package com.trivadis.kafkaws.springcloudstreamkafkaproducer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.stream.annotation.EnableBinding;
import org.springframework.cloud.stream.messaging.Processor;
import java.time.LocalDateTime;
@SpringBootApplication
@EnableBinding(Processor.class)
public class SpringCloudStreamKafkaProducerApplication implements CommandLineRunner {
private static Logger LOG = LoggerFactory.getLogger(SpringCloudStreamKafkaProducerApplication.class);
@Autowired
private KafkaEventProducer kafkaEventProducer;
public static void main(String[] args) {
SpringApplication.run(SpringCloudStreamKafkaProducerApplication.class, args);
}
@Override
public void run(String... args) throws Exception {
LOG.info("EXECUTING : command line runner");
if (args.length == 0) {
runProducer(100, 10, 0);
} else {
runProducer(Integer.parseInt(args[0]), Integer.parseInt(args[1]), Long.parseLong(args[2]));
}
}
private void runProducer(int sendMessageCount, int waitMsInBetween, long id) throws Exception {
Long key = (id > 0) ? id : null;
for (int index = 0; index < sendMessageCount; index++) {
String value = "[" + id + "] Hello Kafka " + index + " => " + LocalDateTime.now();
kafkaEventProducer.produce(index, key, value);
// Simulate slow processing
Thread.sleep(waitMsInBetween);
}
}
}
```
The difference here to the non-avro version is, that we are using the builder of the generated `Nofification` class to create an instance of a notification, which we then pass as the value to the `produce()` method.
### Configure Kafka through application.yml configuration file
First let's rename the existing `application.properties` file to `application.yml` to use the `yml` format.
Add the following settings to configure the Kafka cluster and the name of the topic:
```yml
topic:
name: test-spring-cloud-stream-topic-avro
replication-factor: 3
partitions: 12
spring:
cloud:
stream:
kafka:
bindings:
output:
producer:
configuration:
value.serializer: io.confluent.kafka.serializers.KafkaAvroSerializer
schema.registry.url: http://${DATAPLATFORM_IP}:8081
bindings:
output:
destination: ${topic.name}
producer:
useNativeEncoding: true
kafka:
bootstrap-servers: ${DATAPLATFORM_IP}:9092
```
Here again we switch the value-serializer from `StringSerializer` to the `KafkaAvroSerializer` and add the property `schema.registry.url` to configure the location of the Confluent Schema Registry REST API.
For the IP address of the Kafka cluster we refer to an environment variable, which we have to declare before running the application.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
### Build the application
First lets build the application:
```bash
mvn package -Dmaven.test.skip=true
```
### Use Console to test the application
In a terminal window start consuming from the output topic:
```bash
kafkacat -b $DATAPLATFORM_IP -t test-spring-avro-topic -s avro -r http://$DATAPLATFORM_IP:8081 -o end
```
### Run the application
Now let's run the application
```bash
mvn spring-boot:run
```
Make sure that you see the messages through the console consumer.
To run the producer with custom parameters (for example to specify the key to use), use the `-Dspring-boot.run.arguments`:
```bash
mvn spring-boot:run -Dspring-boot.run.arguments="100 10 10"
```
## Create the Spring Boot Consumer Project
Now let's create an test the Consumer microservice.
### Creating the Spring Boot Project
Use again the [Spring Initializr](https://start.spring.io/) to generate the project.
Select Generate a **Maven Project** with **Java** and Spring Boot **2.6.5**. Enter `com.trivadis.kafkaws` for the **Group**, `spring-boot-cloud-stream-kafka-consumer-avro` for the **Artifact** field and `Kafka Consumer with Avro project for Spring Cloud Stream` for the **Description** field.
Click on **Add Dependencies** and search for the **Cloud Stream** depencency.
Select the dependency and hit the **Enter** key. You should now see the dependency on the right side of the screen.
Click on **Generate Project** and unzip the ZIP file to a convenient location for development.
Once you have unzipped the project, you’ll have a very simple structure.
Import the project as a Maven Project into your favourite IDE for further development.
### Extend the Maven POM with some configurations
In oder to use the Avro deserializer and the Avro generated classes, we have to add the following dependencies to the `pom.xml`.
```xml
<dependencies>
...
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-stream-binder-kafka</artifactId>
</dependency>
<dependency>
<groupId>io.confluent</groupId>
<artifactId>kafka-avro-serializer</artifactId>
<version>${confluent.version}</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>io.confluent</groupId>
<artifactId>kafka-schema-registry-client</artifactId>
<version>${confluent.version}</version>
</dependency>
<dependency>
<groupId>com.trivadis.kafkaws.meta</groupId>
<artifactId>meta</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
```
Add the version of the Confluent Platform to use as an additional property
```xml
<properties>
...
<confluent.version>7.0.0</confluent.version>
</properties>
```
We also have to specify the additional Maven repository
```xml
<repositories>
<repository>
<id>confluent</id>
<url>https://packages.confluent.io/maven/</url>
</repository>
</repositories>
```
### Implement a Kafka Consumer in Spring
Start by creating a simple Java class `KafkaEventConsumer` within the `com.trivadis.kafkaws.springbootkafkaconsumer` package, which we will use to consume messages from Kafka.
```java
package com.trivadis.kafkaws.springcloudstreamkafkaconsumeravro;
import com.trivadis.kafkaws.avro.v1.Notification;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.cloud.stream.annotation.StreamListener;
import org.springframework.cloud.stream.messaging.Processor;
import org.springframework.kafka.support.KafkaHeaders;
import org.springframework.messaging.Message;
import org.springframework.stereotype.Component;
@Component
public class KafkaEventConsumer {
private static final Logger LOGGER = LoggerFactory.getLogger(KafkaEventConsumer.class);
@StreamListener(Processor.INPUT)
public void receive(Message<Notification> msg) {
Notification value = msg.getPayload();
Long key = (Long)msg.getHeaders().get(KafkaHeaders.RECEIVED_MESSAGE_KEY);
LOGGER.info("received key = '{}' with payload='{}'", key, value);
}
}
```
This class uses the `Component` annotation to have it registered as bean in the Spring context and the `KafkaListener` annotation to specify a listener method to be called for each record consumed from the Kafka input topic. The name of the topic is specified as a property to be read again from the `application.yml` configuration file.
In the code we only log the key and value received to the console. In real life, we would probably inject another bean into the `KafkaEventConsumer` to perform the message processing.
### Add @EnableBinding to Application class
Add the following annotation to the `SpringCloudStreamKafkaConsumerAvroApplication` class
```yml
@EnableBinding(Processor.class)
public class SpringCloudStreamKafkaConsumerAvroApplication {
...
```
### Configure Kafka through application.yml configuration file
First let's rename the existing `application.properties` file to `application.yml` to use the `yml` format.
Add the following settings to configure the Kafka cluster and the name of the two topics:
```yml
topic:
name: test-spring-cloud-stream-topic-avro
spring:
cloud:
stream:
kafka:
bindings:
input:
consumer:
configuration:
value.deserializer: io.confluent.kafka.serializers.KafkaAvroDeserializer
schema.registry.url: http://${DATAPLATFORM_IP}:8081
specific.avro.reader: true
bindings:
input:
destination: ${topic.name}
consumer:
useNativeEncoding: true
kafka:
bootstrap-servers:
- ${DATAPLATFORM_IP}:9092
- ${DATAPLATFORM_IP}:9093
```
For the IP address of the Kafka cluster we refer to an environment variable, which we have to declare before running the application.
```bash
export DATAPLATFORM_IP=nnn.nnn.nnn.nnn
```
### Build the application
First lets build the application:
```bash
mvn package -Dmaven.test.skip=true
```
### Run the application
Now let's run the application
```bash
mvn spring-boot:run
```

Let's redo the simple message filtering process of the previous workshop, using Kafka Streams instead of KSQL.
## Create the project in Eclipse IDE
Start the Eclipse IDE if not yet done.
Create a new [Maven project](../99-misc/97-working-with-eclipse/README.md) and in the last step use `com.trivadis.kafkastreams` for the **Group Id** and `kafka-streams-truck` for the **Artifact Id**.
Navigate to the **pom.xml** and double-click on it. The POM Editor will be displayed.
You can either use the GUI to edit your pom.xml or click on the last tab **pom.xml** to switch to the "code view". Let's do that.
You will see the still rather empty definition.
```xml

Refresh the project in Eclipse to re-read the project settings.
## Create log4j settings
Let's also create the necessary log4j configuration.
In the code we are using the [Log4J Logging Framework](https://logging.apache.org/log4j/2.x/), which we have to configure using a property file.
Create a new file `log4j.properties` in the folder **src/main/resources** and add the following configuration properties.
```bash
log4j.rootLogger=OFF, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d] %p [%t] %m (%c)%n
# Enable for debugging if need be
#log4j.logger.org.apache.kafka.streams=DEBUG, stdout
#log4j.additivity.org.apache.kafka.streams=false
# Squelch expected error messages like:
# java.lang.IllegalStateException: This consumer has already been closed.

### Creating the necessary Kafka Topic
We will use the topic `dangerous_driving_kstreams` in the Kafka Streams code below. Due to the fact that `auto.topic.create.enable` is set to `false`, we have to manually create the topic.
Connect to the `broker-1` container
```bash
docker exec -ti broker-1 bash
```
and execute the necessary `kafka-topics` command.
```bash
kafka-topics --bootstrap-server kafka-1:19092,kafka-2:19093 --create --topic dangerous_driving_kstreams --partitions 8 --replication-factor 2
```
Cross check that the topic has been created.
```bash
kafka-topics --list --bootstrap-server kafka-1:19092,kafka-2:19093
```
This finishes the setup steps and our new project is ready to be used. Next we will start implementing the **Kafka Streams Topology**.
## Create a Kafka Streams Topology
First create a new Java Package `com.trivadis.kafkastreams` in the folder **src/main/java**.
Create a new Java Class `TruckPosition ` in the package `com.trivadis.kafkastreams ` just created.
```java
package com.trivadis.kafkastreams;
import org.apache.commons.lang3.StringUtils;
import org.apache.kafka.streams.KeyValue;
public class TruckPosition {
public Long timestamp;
public Integer truckId;
public Integer driverId;
public Integer routeId;
public String eventType;
public Double latitude;
public Double longitude;
public String correlationId;
public TruckPosition() {
}
public static TruckPosition create(String csvRecord) {
TruckPosition truckPosition = new TruckPosition();
String[] values = StringUtils.split(csvRecord, ',');
truckPosition.timestamp = new Long(values[0]);
truckPosition.truckId = new Integer(values[1]);
truckPosition.driverId = new Integer(values[2]);
truckPosition.routeId = new Integer(values[3]);
truckPosition.eventType = values[4];
truckPosition.latitude = new Double(values[5]);
truckPosition.longitude = new Double(values[6]);
truckPosition.correlationId = values[7];
return truckPosition;
}
public String toCSV() {
return timestamp + "," + truckId + "," + driverId + "," + routeId + "," + eventType + "," + latitude + "," + longitude + "," + correlationId;
}
public static boolean filterNonNORMAL(String key, TruckPosition value) {
boolean result = false;
result = !value.eventType.equals("Normal");
return result;
}
@Override
public String toString() {
return "TruckPosition [timestamp=" + timestamp + ", truckId=" + truckId + ", driverId=" + driverId + ", routeId=" + routeId
+ ", eventType=" + eventType + ", latitude=" + latitude + ", longitude="
+ longitude + ", correlationId=" + correlationId + "]";
}
}
```
Create a new Java Class `TruckFilterTopology` in the package `com.trivadis.kafkastreams ` just created.
Add the following code to the empty class to create a Kafka Producer.
```java
package com.trivadis.kafkastreams;
import java.util.Properties;
import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.common.serialization.Serde;
import org.apache.kafka.common.serialization.Serdes;
import org.apache.kafka.streams.KafkaStreams;
import org.apache.kafka.streams.KeyValue;
import org.apache.kafka.streams.StreamsBuilder;
import org.apache.kafka.streams.StreamsConfig;
import org.apache.kafka.streams.kstream.Consumed;
import org.apache.kafka.streams.kstream.KStream;
import org.apache.kafka.streams.kstream.Printed;
public class TruckFilterTopology {
public static void main(String[] args) {
// Serializers/deserializers (serde) for String and Long types
final Serde<String> stringSerde = Serdes.String();
final Serde<Long> longSerde = Serdes.Long();
final String bootstrapServers = args.length > 0 ? args[0] : "dataplatform:9092";
final Properties streamsConfiguration = new Properties();
// Give the Streams application a unique name. The name must be unique in the Kafka cluster
// against which the application is run.
streamsConfiguration.put(StreamsConfig.APPLICATION_ID_CONFIG, "kafka-streams-truck-filter");
// Where to find Kafka broker(s).
streamsConfiguration.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
streamsConfiguration.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "latest");
// Specify default (de)serializers for record keys and for record values.
streamsConfiguration.put(StreamsConfig.DEFAULT_KEY_SERDE_CLASS_CONFIG, Serdes.String().getClass().getName());
streamsConfiguration.put(StreamsConfig.DEFAULT_VALUE_SERDE_CLASS_CONFIG, Serdes.String().getClass().getName());
// In the subsequent lines we define the processing topology of the Streams application.
// used to be KStreamBuilder ....
final StreamsBuilder builder = new StreamsBuilder();
/*
* Consume TruckPositions data from Kafka topic
*/
KStream<String, String> positions = builder.stream("truck_position", Consumed.with(stringSerde, stringSerde));
/*
* Create a Stream of TruckPosition's by parsing the CSV into TruckPosition instances
*/
KStream<String, TruckPosition> positionsTruck = positions.mapValues(value -> TruckPosition.create(value.substring(7, value.length())));
positionsTruck.peek((k, v) -> System.out.println (k + ":" +v));
/*
* Non stateful transformation => filter out normal behaviour
*/
KStream<String, TruckPosition> positionsTruckFiltered = positionsTruck.filter(TruckPosition::filterNonNORMAL);
/*
* Convert the Truck Position back into a CSV format and publish to the dangerous_driving_kstreams topic
*/
positionsTruckFiltered.mapValues(value -> value.toCSV()).to("dangerous_driving_kstreams");
// Create the topology
final KafkaStreams streams = new KafkaStreams(builder.build(), streamsConfiguration);
// clean up all local state by application-id
streams.cleanUp();
streams.setUncaughtExceptionHandler((Thread thread, Throwable throwable) -> {
System.out.println("Within UncaughtExceptionHandler =======>");
System.out.println(throwable);
// here you should examine the throwable/exception and perform an appropriate action!
});
// Start the topology
streams.start();
// Add shutdown hook to respond to SIGTERM and gracefully close Kafka Streams
Runtime.getRuntime().addShutdownHook(new Thread(streams::close));
}
}
```
With these 2 classes in place, we can run the TruckFilterTopology as an Application from within the IDE.
After some time you should start seeing the output of the `peek` operation on the `positionsTruck` stream.
Now let's see that we actually produce data on that new topic by running a `kafka-console-consumer` or alternatively a `kafkacat`.
```bash
docker exec -ti broker-1 bash
```
```bash
kafka-console-consumer --bootstrap-server broker-1:9092 --topic dangerous_driving_kstreams
```
You should only see events for abnormal driving behaviour.

# Password Generator
Live URL: http://p2.jrwebdev.me
## Description
This project is a password generator inspired by the [xkcd comic](http://xkcd.com/936/).
The user can specify the number of words to use (from 1 to 5), and the number of special characters and/or digits.
When clicking on the *Generate!* button a new password is generated.
The words were taken by scraping a website with common english words.
It was built from scratch on PHP.
[View Screencast Demo](https://youtu.be/WgbifXGPJ28)
## Info for TA's
Please check the comment that starts with *NOTE for TA's* on the *logic.php* file.
## Things that can be improved/fixed
There is a small glitch when clicking the *Generate!* button that makes the main *div* shrink and grow back again.
Instead of scraping the web every time a user goes to the site, it would be better to scrape once for a large word base and save the words in a file for future use.

<file_sep># e-Progest Exercice PHP
J'ai utilisé le framework Symfony pour concevoir l'exercice en PHP.
### Les outils
* PHP 7.2
* MySQL
* Composer
### Installation du projet
```php
$ git clone git://github.com/Poniav/eProgestExo.git
$ cd eProgestExo
// Editer le fichier .env pour la connexion SQL
$ composer install
$ php bin/console doctrine:database:create
$ php bin/console make:migration ( development )
$ php bin/console doctrine:migrations:migrate
$ php bin/console server:run
```
## Base de données
Il y a deux façons de récupérer les utilisateurs dans la base de données. Soit en chargeant les fixtures avec la commande ci-dessous ou alors en récupérant le fichier SQL à la racine du projet dans DB.
```php
$ php bin/console doctrine:fixtures:load
```
## Infos
J'ai pas configuré la protection CSRF sur les formulaires.

# Aplicativo Me Responda: "Me faça uma pergunta?" :question::smiley:
Assista o vídeo a seguir:
[](http://www.youtube.com/watch?v=mFOracFClBg "<NAME>")
## Introdução:
. Você já quis estar mais próximo de brinquedos antigos que hoje em dia estão difíceis de achar?
Pois aqui está a sua chance de desfrutar de um dos brinquedos mais famosos de 1995, a Magic Ball.
. Este Repositório representa mais uma de minhas conquistas como desenvolvedora de apps. A partir dela eu pude desenvolver novas práticas e novos conhecimentos relacionados ao Android Studio, ao Kotlin e ao Design.
## Objetivo | "Desenho animado é coisa de criança?" :older_woman::older_man::girl::baby::man_with_gua_pi_mao:
A importância da animação vai além das fronteiras da infância. Ele tem uma relevância atemporal, pois promove a interação entre pessoas, sejam elas de gerações, lugares e/ou culturas diferentes.
Cabe ressaltar que, segundo a Flow (psicologia positiva), os desenhos animados, assim como, os curta-metragem e longa-metragem estimulam o lado criativo do indivíduo e desenvolvem o hábito de demonstrar as emoções de forma mais positiva. Por conta disso e de outros fatores, devemos ter em mente que o desenhos animados não são apenas para crianças, mas eles também são feitos para a nossa criança interna, ou seja, para os adultos.
A partir de uma cena da longa-metragem Toy Storie ,eu desenvolvi esse app! O meu objetivo é mostrar para os Devs, de todas as idades, que a tecnologia, assim como os desenhos, são apenas brinquedos que podemos utilizar para mudar o mundo de todas as formas possíveis e impossíveis!
## Este Projeto tem como base: :books:
. Kotlin;
. Android Studio;
. Figma.
## Interface do app: :calling:
## Indicação de filmes e desenhos para adultos e crianças desenvolverem a sua criatividade:
. Divertida Mente (<NAME> 2015 - 102 minutos);
. O menino e o mundo (Alê Abreu 2014 - 80 minutos);
. WALL-E (<NAME> 2008 - 103 minutos);
. Wallace e Gromit e a Batalha dos Vegetais (Nick Park 2005 - 95 minutos);
. Meu amigo Totoro (Hayao Miyaki 1988 - 86 minutos).

title: "Road Safety - Accidents in UK, 2014"
output: html_document

```{r set-options, echo=FALSE, cache=FALSE}
options(width = 200)
```
___
#### *Authors:* <NAME> & <NAME>
#### *Date*: April 13, 2016
#### *The Dataset [Source](https://data.gov.uk/dataset/road-accidents-safety-data)*
___
### *Data Description*
- This file provide detailed road safety data about the circumstances of personal injury road accidents from 2014, UK, the types (including Make and Model) of vehicles involved and the consequential casualties.
- The statistics relate only to personal injury accidents on public roads that are reported to the police, and subsequently recorded, using the STATS19 accident reporting form.
- The relevant properties in the dataset:
Properties | Description
----------------------- | ------------------------------------------
*Accident_Index* | **ID** number of an accident
*Longitude* | The **longitude** of the place where the accident happened
*Latitude* | The **latitude** of the place where the accident happened
*Number_of_Vehicles* | The number of **vehicles** in the accident
*Number_of_Casualties* | The number of **casualties** in the accident
*Date* | The **date** on which the accident occurred
*Day_of_Week* | The **day** of week on which the accident occurred
*Time* | The **time** on which the accident occurred
___
### *Data Example - Reading first data records*
```{r include= TRUE, echo=FALSE}
library("downloader")
folder<-".\\data\\DfTRoadSafety_Accidents_2014.csv"
if(!file.exists(folder)){
# Download a csv file from the Internet:
fileURL <- "https://dl.dropboxusercontent.com/u/73991112/DfTRoadSafety_Accidents_2014.csv"
download.file(fileURL, destfile = folder)
# Always record the date
dateDownloaded <- date()
dateDownloaded
}
# Read from local drive
accidentsData <- read.csv(folder, sep = ",",header = T, row.names=NULL)[,c(1,4:5,8:12)]
# Reading the first records :
head(accidentsData)
```
___
### *Summary*
- Statistics on the number of **vehicles** and **casualties** that were involved in an accident:
```{r echo=FALSE}
summary(accidentsData[,c(4:5)])
```
___
### *Analysis of the Data by Various Criteria*
___
#### *The graph below shows the **distribution** of accidents in the **UK***
```{r include= TRUE, echo=FALSE, warning=FALSE}
library(MASS)
library(RgoogleMaps)
# Keep the lon and lat data
rawdata <- data.frame(as.numeric(accidentsData$Longitude), as.numeric(accidentsData$Latitude))
names(rawdata) <- c("lon", "lat")
# Mapping via RgoogleMaps
# Find map center and get map
center <- rev(sapply(rawdata, mean))
map <- GetMap(center=center, zoom=7)
# Translate original data
coords <- LatLon2XY.centered(map, rawdata$lat, rawdata$lon, 7)
coords <- data.frame(coords)
# Plot
PlotOnStaticMap(map)
points(coords$newX, coords$newY, pch=16, cex=0.3, col=heat.colors(12,0.1))
```
As can be seen from the graph, the majority of road accidents occur in **urban areas**.
This phenomenon is a logical result because:
- The **number of vehicles** in urban areas is higher than in non-urban areas.
- In urban areas there is **activity around the clock**, as opposed to areas that are not urban.
___
#### *The graph below shows the **distribution** of road accidents during **the week***
```{r include= TRUE, echo=FALSE, warning=FALSE}
# Pie Chart from data frame with Appended Sample Sizes
mytable <- table(accidentsData$Day_of_Week)
days<-c('Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday')
bls <- paste(days, "\n",mytable , sep="")
pie(mytable, labels =bls, main="Pie Chart of accidents during\ndays of the week",col=terrain.colors(7))
```
As can be seen from the graph:
- The **majority** of road accidents occur in **Friday**.
- The **minority** of road accidents occur in **Sunday**.
This phenomenon is a logical result because:
- Most people in UK drive on **Friday** to make arrangements ahead of the weekend, what creating congestion on the roads, which leads to a **high number of accidents** on this day.
- Most people in the UK do not drive on **Sunday** - it is a **day off** - so there are few cars on the road which leads a **small number of road accidents** on this day.
___
#### *The graph below shows the **distribution** of accidents in the during **the day***
```{r include= TRUE, echo=FALSE, warning=FALSE}
hist(as.numeric(substr(accidentsData$Time,1,2)),main="Histogram for Number of Accidents\nVS\nHour", xlab="Hour",col=terrain.colors(24), ylab="Number of Accidents",las = 1)
```
As can be seen from the graph:
- The **majority** of road accidents occur in **17:00-18:00**.
- The **minority** of road accidents occur in **03:00:04:00**.
This phenomenon is a logical result because:
- Most people in UK drive back home in **17:00-18:00**, what creating congestion on the roads, which leads to a **high number of accidents** on this day.
- Most people in the UK do not drive in **03:00:04:00**, so there are few cars on the road which leads a **small number of road accidents** on this day.
___
### *Summary, Conclusions and Recommendations for Further Research.*
In conclusion, this report shows that road accidents have common attributes, such as **day, time and location** - that can learn from and draw on some of the reasons why they happen.
Our recommendation for further research, is to cross-check between the common attributes that presented in this report and deduce information that could indicate **when and where** there is a likelihood that a road accident will happend.
After analyzing this information, it will be possible to increase the presence of police forces in order to reduce the quantity of traffic accidents and thereby save lives.
