-----------------------------------------
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.
