spring-cloud-stream - producer.headerMode default value

Question

probably anyone know which value is default for spring.cloud.stream.bindings.<bindingName>.producer.header-mode in spring-cloud-stream-kafka-binder?

The problem is because in spring-cloud stream documentation we have

Default: Depends on the binder implementation.

Answer 1

Default is headers for the Apache Kafka binder.

In general, you can assume that for middleware that supports headers natively (e.g. Kafka since 0.11.0.0), the default will be headers; for middleware that has no support for headers, it will be embeddedHeaders or none depending on what the developer chose.
