------------------------------

             Summary: Improved filtering performance for a large number of partitions in a single table.
                 Key: HIVE-20199
                 URL: https://issues.apache.org/jira/browse/HIVE-20199
             Project: Hive
          Issue Type: Improvement
          Components: Metastore
            Reporter: Biao Wu
            Assignee: Biao Wu


eg:
{code:sql}
select * from test where dt = '20180606'
{code}
The filter 'dt=20180606' will be pushed down to mysql for execution, but the test table contains a large number of partitions, this is a poor performance.
