-----------------------------------
Summary: Idempotent producer: a producerId reset causes
undesirable behavior for inflight batches to other partitions
Key: KAFKA-5870
URL: https://issues.apache.org/jira/browse/KAFKA-5870
Project: Kafka
Issue Type: Bug
Affects Versions: 0.11.0.0
Reporter: Apurva Mehta
Assignee: Apurva Mehta
Fix For: 1.0.0
Currently, if we have to reset the producer id for any reason (for instance if
batches to a partition get expired, if we get an
{{OutOfOrderSequenceException}}, etc) we could cause batches to other
--healthy-- partitions to fail with a spurious {{OutOfOrderSequenceException}}.
This is detailed in this PR discussion:
https://github.com/apache/kafka/pull/3743#discussion_r137907630
Ideally, we would want all inflight batches to be handled to completion rather
than potentially failing them prematurely. Further, since we want to tighten up
the semantics of the {{OutOfOrderSequenceException}}, at the very least we
should raise another exception in this case, because there is no data loss on
the broker when the client gives up.
