----------------------------------
Summary: Consumer group coordinator should take commit requests as
effective as heartbeats
Key: KAFKA-3470
URL: https://issues.apache.org/jira/browse/KAFKA-3470
Project: Kafka
Issue Type: Improvement
Reporter: Zaiming Shi
Group coordinator does not reset heartbeat timer when commit request is
received.
This may lead to unnecessary session timeouts when a consumer sends
sync commit requests so frequently that causes heartbeat requests to be
delayed.
Presumably (as I do not know Kafka code well):
Commit requests (v1/v2) have all data fields for a heartbeat request,
If they are taken as effective as heartbeat requests, we should have
better group stability.
[For reference]
previous discussions in: [email protected]
mail title: consumer group, why commit requests are not considered as
effective heartbeats?
