Connecting to multiple clusters spring kafka

Question

I would like to consume messages from one kafka cluster and publish to another kafka cluster. Would like to know how to configure this using spring-kafka?

Answer 1

Simply configure the consumer and producer factories with different bootstrap.servers properties.

If you are using Spring Boot, see

https://docs.spring.io/spring-boot/docs/current/reference/html/appendix-application-properties.html#spring.kafka.consumer.bootstrap-servers

and

https://docs.spring.io/spring-boot/docs/current/reference/html/appendix-application-properties.html#spring.kafka.producer.bootstrap-servers

If you are creating your own factory @Beans, set the properties there.
