> Consumer group coordinator should take commit requests as effective as

> ---------------------------------------------------------------------------------
>
> Key: KAFKA-3470
> URL: https://issues.apache.org/jira/browse/KAFKA-3470
> Project: Kafka
> Issue Type: Improvement
> Reporter: Zaiming Shi
> Assignee: Jason Gustafson
> Fix For: 0.10.0.0
>
>
> 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 and 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?
