See https://docs.spring.io/spring-kafka/reference/html/_reference.html#_configuration[the Spring Kafka documentation].
To modify this behavior simply add a single `CleanupConfig` `@Bean` (configured to clean up on start, stop, or neither) to the application context; the bean will be detected and wired into the factory bean.
=== Kafka Streams topology visualization
Kafka Streams binder provides the following actuator endpoints for retrieving the topology description using which you can visualize the topology using external tools.
`/actuator/topology`
`/actuator/topology/<applicaiton-id of the processor>`
You need to include the actuator and web dependencies from Spring Boot to access these endpoints.
Further, you also need to add `topology` to `management.endpoints.web.exposure.include` property.
By default, the `topology` endpoint is disabled.
=== Configuration Options
This section contains the configuration options used by the Kafka Streams binder.
