-----------------------------------
Summary: Move static request validation from GroupMetadataManager
to GroupCoordinatorService
Key: KAFKA-17745
URL: https://issues.apache.org/jira/browse/KAFKA-17745
Project: Kafka
Issue Type: Sub-task
Reporter: David Jacot
At the moment, we validate the request in the GroupMetadataManager. It means
that the validation runs within the group coordinator threads. In case of rogue
requests, it would unnecessarily use resources from those threads. It would be
better to do the static validation in the GroupCoordinatorService while still
running in the request handler threads. I haven't looked into all the details
but it seems feasible.
