Lianet Magrans updated KAFKA-16984:
-----------------------------------
Summary: New consumer should not complete leave operation until it gets a
response (was: New consumer should wait for leave group response to avoid
responses to disconnected clients)
> New consumer should not complete leave operation until it gets a response

> Key: KAFKA-16984
> URL: https://issues.apache.org/jira/browse/KAFKA-16984
> Project: Kafka
> Issue Type: Bug
> Components: clients, consumer
> Affects Versions: 3.8.0
> Reporter: Lianet Magrans
> Assignee: Lianet Magrans
> Priority: Major
> Labels: kip-848
> Fix For: 3.9.0
>
>
> When the new consumer attempts to leave a group, it sends a leave group
> request in a fire-and-forget mode, so it transitions to UNSUBSCRIBED as soon
> as it generates the requests (without waiting for a response. Note that this
> transition to unsubscribe marks the leave operation as completed. This makes
> that, when leaving a group while closing a consumer, the member sends the
> leave request and moves on to next operation, which is closing the network
> thread, so we end up with disconnected client receiving responses from the
> server. We should send leave group heartbeat, and transition to UNSUBSCRIBE
> (completes the leave operation) only when we get a response for it, which is
> a much more accurate confirmation that the consumer left the group and can
> move on with other operations
