At the moment, I think the answer is yes. The old broker will not support the InitProducerId request, so the producer will immediately fail. Similar to the handling of old message formats mentioned above, we probably need to change this so that we just revert to old producer semantics if the broker can't support idempotence. -Jason On Fri, Aug 18, 2017 at 8:48 AM, Manikumar <manikumar.re...@gmail.com> wrote: > > > > 3.
