The main goal is to play with Kafka Connect and Streams. We have store-api that inserts/updates records in MySQL; Source connectors that monitor inserted/updated records in MySQL and push messages related to those changes to Kafka; Sink connectors that read messages from Kafka and insert documents in ES; Store-streams that listens for messages in Kafka, treats them using Kafka Streams and push new messages back to Kafka. - View it on GitHub
