[jira] [Created] (KAFKA-8585) Controller should make LeaderAndIsr updates optimistically

Jason Gustafson created KAFKA-8585:
--------------------------------------

             Summary: Controller should make LeaderAndIsr updates optimistically
                 Key: KAFKA-8585
                 URL: https://issues.apache.org/jira/browse/KAFKA-8585
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jason Gustafson
            Assignee: Jason Gustafson


Before the controller updates LeaderAndIsr information for a set of partitions, it always first looks up the current state. We can skip this since the state is already cached on the controller. In the common case (e.g. controlled shutdown), the update will succeed. If there was a change which had not been propagated to the controller, we can retry (this logic exists already).
