[jira] [Created] (HIVE-25189) Cache the validWriteIdList in query cache before fetching tables from HMS

Steve Carlin created HIVE-25189:
-----------------------------------

             Summary: Cache the validWriteIdList in query cache before fetching tables from HMS
                 Key: HIVE-25189
                 URL: https://issues.apache.org/jira/browse/HIVE-25189
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2
            Reporter: Steve Carlin


For a small performance boost at compile time, we should fetch the validWriteIdList before fetching the tables.  HMS allows these to be batched together in one call.  This will avoid the getTable API from being called twice, because the first time we call it, we pass in a null for validWriteIdList.
