> Otherwise, Streams app that run with 2.8 and before might not be compatible with Streams 3.0 because the retention time of the changelog topics created with older Streams apps will be smaller than the assumed retention time for Streams apps in 3.0. Why would this be fatal? It seems in 3.0 the retention time would potentially become _larger_ (if a new changlog topic is created). And for any existing application, we won't reconfigure the topic config. While I agree that we should keep the behavior in-sync, I don't see how there could be data loss? -- This is an automated message from the Apache Git Service.
