How to implement a microservice Event Driven architecture with Spring Cloud Stream Kafka and Database per service

Question

I think the proper way for implementing Event Sourcing is by having Kafka be filled directly from events pushed by a plugin that reads from the RDBMS binlog e.g using Confluent BottledWater (https://www.confluent.io/blog/bottled-water-real-time-integration-of-postgresql-and-kafka/) or more active Debezium (http://debezium.io/). Then consuming Microservices can listen to those events, consume them and act on their respective databases being eventually consistent with the RDBMS database.
