[jira] [Created] (HAWQ-1446) Introduce vectorized profile for ORC

Oleksandr Diachenko created HAWQ-1446:
-----------------------------------------

             Summary: Introduce vectorized profile for ORC
                 Key: HAWQ-1446
                 URL: https://issues.apache.org/jira/browse/HAWQ-1446
             Project: Apache HAWQ
          Issue Type: New Feature
          Components: PXF
            Reporter: Oleksandr Diachenko
            Assignee: Ed Espino


As for now, PXF has HiveORC format which supports reading ORC files with leveraging ORC's file advantages(column projections, predicate push-downs).
 The only drawback of this profile - it still operates on a single row. So the idea is to implement a profile for reading ORC files, but operate on batches of rows, which supposed to be faster on reading and resolution phases.
