[jira] [Created] (KAFKA-9637) Create separate state directory to manage locks

Boyang Chen created KAFKA-9637:
----------------------------------

             Summary: Create separate state directory to manage locks
                 Key: KAFKA-9637
                 URL: https://issues.apache.org/jira/browse/KAFKA-9637
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Boyang Chen


https://issues.apache.org/jira/browse/KAFKA-9618

has exposed a race condition when the owned-by-other-thread state was trying to be deleted. We could create a directory like {{state_locks}} which maintains all the locks of state stores, so that the dir deletion won't affect the thread locking behavior.
