----------------------------------
Summary: Enable batching in FindCoordinator
Key: KAFKA-7206
URL: https://issues.apache.org/jira/browse/KAFKA-7206
Project: Kafka
Issue Type: Improvement
Components: admin
Reporter: Yishun Guan
To quote [~guozhang]
"The proposal is that, we extend FindCoordinatorRequest to have multiple
consumer ids: today each FindCoordinatorRequest only contains a single consumer
id, so in our scenario we need to send N request for N consumer groups still.
If we can request for coordinators in a single request, then the workflow could
be simplified to:
# send a single FindCoordinatorRequest to a broker asking for coordinators of
all consumer groups.
1.a) note that the response may still succeed in finding some coordinators
while error on others, and we need to handle them on that granularity (see
below).
# and then for the collected coordinator, group them by coordinator id and
send one request per coordinator destination.
Note that this change would require the version to be bumped up, to
{{FIND_COORDINATOR_REQUEST_V3}}for such protocol changes, also the RESPONSE
version should be bumped up in order to include multiple coordinators."
