Subject [jira] [Created] (HIVE-5549) ql partition object may not be necessary; pruner might be able to return MPartition-s
Date Tue, 15 Oct 2013 18:42:47 GMT
Sergey Shelukhin created HIVE-5549:
--------------------------------------

             Summary: ql partition object may not be necessary; pruner might be able to return
MPartition-s
                 Key: HIVE-5549
                 URL: https://issues.apache.org/jira/browse/HIVE-5549
             Project: Hive
          Issue Type: Improvement
          Components: Metastore
            Reporter: Sergey Shelukhin
            Priority: Minor


For code cleanup, and to improve perf a bit, it is possible to get rid of ql Partition object
in many places. PrunedPartitionsList can have MPartitions inside; for many if not all users
of it, it will be sufficient.
If we find Partition objects is categorically needed somewhere we can convert inside it when
needed.
