Summary: Broker fixes for smooth concurrent fetches on share
partition
Key: KAFKA-17210
URL: https://issues.apache.org/jira/browse/KAFKA-17210
Project: Kafka
Issue Type: Sub-task
Reporter: Abhinav Dixit
Assignee: Abhinav Dixit
Identified a couple of reliability issues with broker code for share groups -
# Broker seems to get stuck at times when using multiple share consumers due
to a corner case where the second last fetch request did not contain any topic
partition to fetch, because of which the broker could never complete the last
request. This results in a share fetch request getting stuck.
# Since persister would not perform any business logic around sending state
batches for a share partition, there could be scenarios where it sends state
batches with no AVAILABLE records. This could cause a breach on the limit of
in-flight messages we have configured, and hence broker would never be able to
complete the share fetch requests.
