[jira] [Created] (DRILL-6053) Avoid excessive locking in LocalPersistentStore

Vlad Rozov created DRILL-6053:
---------------------------------

             Summary: Avoid excessive locking in LocalPersistentStore
                 Key: DRILL-6053
                 URL: https://issues.apache.org/jira/browse/DRILL-6053
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Vlad Rozov
            Assignee: Vlad Rozov


When query profiles are written to LocalPersistentStore, the write is unnecessary serialized due to read/write lock that was introduced for versioned PersistentStore. Only versioned access needs to be protected by read/write lock.
