With respect to the retries. There is currently a known error where if we produce using an idempotent producer we can get stuck in a retry loop. 1. Request A with sequence 0 fails with a retriable error 2. Request B with sequence 1 succeeds. Because we currently don't assert the sequence is 0 on the first records written (or any records written when we don't yet have producer state, this will succeed) 3. Request A will be retried and will always fail with a retriable OutOfOrderSequence error. Imagine at step 2, we have a request C that fails with a non-retriable error. Will we get stuck waiting for Request A until the retries run out? The default is pretty high so this will go on for some time. BTW this issue is https://issues.apache.org/jira/browse/KAFKA-14359, and we are still considering the best way to fix it. -- This is an automated message from the Apache Git Service.
