No, there's no change for messages 9+. So, I think your understanding is correct. When client and server are using the same compression codec, it won't do conversion. What you need to do now is to make sure the "server" and the "topic" is not using the compression codec. You can try to describe the topic to check if the compression.type config is set. The default value for `compression.type` is `producer`, which means, it'll store what it got from producer, won't do conversion. https://kafka.apache.org/documentation/#brokerconfigs_compression.type Thank you.
