--------------------------------------
Summary: Try complete actions after callback
Key: KAFKA-15380
URL: https://issues.apache.org/jira/browse/KAFKA-15380
Project: Kafka
Issue Type: Sub-task
Reporter: Justine Olshan
Assignee: Justine Olshan
KIP-890 part 1 introduced the callback request type. It is used to execute a
callback after KafkaApis.handle has returned. We did not account for
tryCompleteActions at the end of handle when making this change.
In tests, we saw produce p99 increase dramatically (likely because we have to
wait for another request before we can complete DelayedProduce). As a result,
we should add the tryCompleteActions after the callback as well. In testing,
this improved the produce performance.
