------------------------------------
Summary: Support fields that are not yet supported in StreamsGroup.
Key: KAFKA-20248
URL: https://issues.apache.org/jira/browse/KAFKA-20248
Project: Kafka
Issue Type: Task
Components: clients, streams
Reporter: sanghyeok An
Assignee: sanghyeok An
According to KIP-1071, the StreamsGroup protocol is required to support various
fields. However, at the client level, this is not fully implemented yet.
For example, as you can see in this code, KIP-1071 specifies that fields such
as {{rackId}} should be set when present, but they are not currently included
in the client request. {{rackId}} is an important factor in determining the
group epoch in the Streams protocol.
(https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/consumer/internals/StreamsMembershipManager.java#L295-L310)
Although these fields are explicitly defined in the KIP-1071 document, they are
not yet included in the actual client request. The goal of this ticket is to
support such fields that are defined in KIP-1071 but are still missing from the
client request.
