-----------------------------------------
Assignee: Oleksandr Diachenko (was: Ed Espino)
> 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: Oleksandr Diachenko
>
> 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.
