             Summary: Missing Index on Hive metastore query
                 Key: HIVE-7906
                 URL: https://issues.apache.org/jira/browse/HIVE-7906
             Project: Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 0.13.1

When it comes to SELECT statement on a table with large number of partitions, the query in the word document below causes major performance degradation. Adding this missing index to turn index scan into seek.
