The goal of this project is to play with Kafka, Debezium and ksqlDB. For this, we have: research-service that inserts/updates/deletes records in MySQL; Source Connectors that monitor change of records in MySQL and push messages related to those changes to Kafka; Sink Connectors and kafka-research-consumer that listen messages from Kafka and insert/update documents in Elasticsearch; finally, ksqlDB-Server that listens to some topics in Kafka, does some joins and pushes new messages to new topics in Kafka.
