As a referred in the following spring cloud documentation:
https://cloud.spring.io/spring-cloud-stream-binder-kafka/spring-cloud-stream-binder-kafka.html#kafka-producer-properties

Particularly this phrase

To avoid repetition, Spring Cloud Stream supports setting values for all channels, in the format of spring.cloud.stream.default.=.

I want to configure kafka producer for all channels using the "default" prefix but this is not functioning. I found a solution which is not respecting the official documentation, please see below the configuration the 2 configurations

correct configuration respecting documentation but not functioning

spring.cloud.stream.default.producer.sync=false
spring.cloud.stream.default.producer.batchTimeout=60000
spring.cloud.stream.default.producer.compression=gzip

functioning configuration but not respecting documentation

spring.cloud.stream.kafka.default.producer.sync=false
spring.cloud.stream.kafka.default.producer.batchTimeout=60000
spring.cloud.stream.kafka.default.producer.compression=gzip

Please confirm that the second configuration is correct and in this case update the official documentation.

I'm using the last version of spring cloud
<spring-cloud.version>2023.0.0</spring-cloud.version>

Thanks
