[jira] [Created] (SPARK-27727) Asynchronous ElementStore cleanup should have only one pending cleanup per class

David C Navas created SPARK-27727:
-------------------------------------

             Summary: Asynchronous ElementStore cleanup should have only one pending cleanup per class
                 Key: SPARK-27727
                 URL: https://issues.apache.org/jira/browse/SPARK-27727
             Project: Spark
          Issue Type: Sub-task
          Components: Spark Core
    Affects Versions: 2.3.3
            Reporter: David C Navas
         Attachments: AsyncDefer.pdf

If ElementTrackingStore cleanup work takes too long to run, the asynchronous requests to run the cleanup can backup in the executor.  Although eventually these requests will do nothing (or very little), they are a potential source of semi-permanent memory use/leaks.
