---------------------------------
Summary: Implement client support for KIP-848
ConsumerGroupHeartbeat protocol RPC
Key: KAFKA-15278
URL: https://issues.apache.org/jira/browse/KAFKA-15278
Project: Kafka
Issue Type: Task
Components: clients, consumer
Reporter: Kirk True
Assignee: Kirk True
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.
