Kafka Event Consumer

The grid is made up of multiple event stores. We have two primary ways of those events being generated:

• user action
  • HTTP Request via the REST API
• system reaction
  • Taking events from a queue

This modules focuses on the latter.

In principle all we have to do is:

• Take event from queue
• Discriminate based on operation type
• Forward to RestAPI
