name: Dispatch analytics

# PROCESS
#
# 1. Trade GitHub JWT token with AWS credentials for the analytics account
# 2. Invoke a Lambda function dispatcher synchronously with the read-only scoped JWT token
# 3. The dispatcher function will call GitHub APIs to read data from the last hour and aggregate for operational analytics

# USAGE
#
# NOTE: meant to use as a scheduled task only (or manually for debugging purposes).
