------------------------------------
Summary: Fix bugs in handling piggyback acknowledgements in
ShareFetch
Key: KAFKA-18016
URL: https://issues.apache.org/jira/browse/KAFKA-18016
Project: Kafka
Issue Type: Sub-task
Reporter: Shivsundar R
Currently, when a ShareFetch is processed and response is received, we use the
fetchAcknowledgements map to determine the acknowledgements sent per partition
and call the callback accordingly. But there is a chance this map was updated
by the ShareFetchEvent before the response was processed.
This means we could potentially lose out on sending acknowledgements. This bug
was found while testing using the ShareRoundTripWorker with 100k records and a
target production rate of 1000 messages per second.
