             Summary: Improve KRaft add voter handling to tolerate waiting for delayed operations
                 Key: KAFKA-17147
                 URL: https://issues.apache.org/jira/browse/KAFKA-17147
             Project: Kafka
          Issue Type: Sub-task
          Components: kraft
            Reporter: José Armando García Sancio
            Assignee: José Armando García Sancio


The current implementation for AddVoter returns an REQUEST_TIMED_OUT error anytime it needs to wait for an invariant to be satisfied. From [https://cwiki.apache.org/confluence/display/KAFKA/KIP-853%3A+KRaft+Controller+Membership+Changes#KIP853:KRaftControllerMembershipChanges-Handling.3:]

 
 # Wait until there are no uncommitted VotersRecord. Note that the implementation may just return a {{REQUEST_TIMED_OUT}} error if there are pending operations.
 # Wait for the LeaderChangeMessage control record from the current epoch to get committed. Note that the implementation may just return a {{REQUEST_TIMED_OUT}} error if there are pending operations.
 # ...

This algorithm could be improved to wait for the invariant to become true instead of returning a timeout immediately.
