Kirk True updated KAFKA-15548:
------------------------------
Description:
Upon closing of the {{Consumer}} we need to:
# Complete pending commits
# Auto-commit if needed
# Send the last GroupConsumerHeartbeatRequest with epoch = -1 to leave the
group
# Close any fetch sessions on the brokers
# Poll the NetworkClient to complete pending I/O
There is a mechanism introduced in PR
[14406|https://github.com/apache/kafka/pull/14406] that allows for performing
network I/O on shutdown. The new method
{{DefaultBackgroundThread.runAtClose()}} will be executed when
{{Consumer.close()}} is invoked.
