Subject [jira] Created: (HIVE-1750) Remove Partition Filtering Conditions when Possible
Date Tue, 26 Oct 2010 02:49:19 GMT
Remove Partition Filtering Conditions when Possible
---------------------------------------------------

                 Key: HIVE-1750
                 URL: https://issues.apache.org/jira/browse/HIVE-1750
             Project: Hive
          Issue Type: Improvement
            Reporter: Siying Dong


For some simple queries, partition filtering constraints take 8% of CPU time (now 16% since
we filter twice) even if the result is always true. When possible, we should remove these
constraints to save CPU times.
