[jira] [Created] (HIVE-21787) Metastore table cache enhancement

Sam An created HIVE-21787:
-----------------------------

             Summary: Metastore table cache enhancement
                 Key: HIVE-21787
                 URL: https://issues.apache.org/jira/browse/HIVE-21787
             Project: Hive
          Issue Type: New Feature
          Components: Standalone Metastore
            Reporter: Sam An
            Assignee: Sam An


Metastore currently uses black/white list to specify patterns of tables to load into the cache. Cache is loaded in one shot "prewarm", and updated by a background thread. This is not a very efficient design. 

In this feature, we try to enhance the cache for Tables with LRU to improve cache utilization.
