Oleksandr Diachenko reassigned HAWQ-1446: ----------------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
