> ------------------------------------------------------------------------
>
> Key: KAFKA-15278
> URL: https://issues.apache.org/jira/browse/KAFKA-15278
> Project: Kafka
> Issue Type: Sub-task
> Components: clients, consumer
> Reporter: Kirk True
> Priority: Major
> Labels: consumer-threading-refactor, kip-848,
> kip-848-client-support
>
> The protocol introduces three new RPCs that the client uses to communicate
> with the broker:

> The necessary Java code that represents the {{ConsumerGroupHeartbeatRequest}}
> and {{ConsumerGroupHeartbeatResponse}} are already present in the codebase.
> It is assumed that the scaffolding for the other two will come along in time.
> * Implement {{ConsumerGroupRequestManager}}
> * Ensure that {{DefaultBackgroundThread}} correctly calculates I/O timeouts
> so that the heartbeat occurs within the {{group.consumer.session.timeout.ms}}
> interval regardless of other {{RequestManager}} instance activity
> This task is part of the work to implement support for the new KIP-848
> consumer group protocol.
