-----------------------------------
Summary: The producerId can be reset unnecessarily
Key: KAFKA-5897
URL: https://issues.apache.org/jira/browse/KAFKA-5897
Project: Kafka
Issue Type: Improvement
Affects Versions: 0.11.0.0, 1.0.0
Reporter: Apurva Mehta
Currently, we expire batches and reset the producer id in cases where we don't
need to.
For instance, if a batch which has been previously sent is expired in the
accumulator, the producerId is reset (or the transaction aborted)
unconditionally. However, if the batch failed with certain error codes like
{{NOT_LEADER_FOR_PARTITION}}, etc., which definitively indicate that the write
never succeeded, we don't need to reset the producer state since the status of
the batch is not in doubt.
Essentially, we would like an 'reset based on failure mode' logic which would
be a bit smarter.
