> Project: Kafka
> Issue Type: Sub-task
> Components: consumer
> Reporter: Onur Karaman
> Assignee: Onur Karaman
> Priority: Minor
> Fix For: 0.8.3
>
>
> Let's say every consumer in a group has session timeout s. Currently, if a
> consumer leaves the group, the worst case time to stabilize the group is 2s
> (s to detect the consumer failure + s for the rebalance window). If a
> consumer instead can declare they are leaving the group, the worst case time
> to stabilize the group would just be the s associated with the rebalance
> window.
> This is a low priority optimization!
