Biao Wu created HIVE-20199:
------------------------------
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.
