> Support ORC as a native file format
> -----------------------------------
>
> Key: HAWQ-864
> URL: https://issues.apache.org/jira/browse/HAWQ-864
> Project: Apache HAWQ
> Issue Type: New Feature
> Components: Storage
> Affects Versions: 2.4.0.0
> Reporter: Lei Chang
> Assignee: Ruilong Huo
> Priority: Major
> Fix For: backlog
>
>
> ORC (Optimized Row Columnar) is a very popular open source format adopted in
> some major
> components in Hadoop ecosystem. It is also used by a lot of users. The
> advantages of
> supporting ORC storage in HAWQ are in two folds: firstly, it makes HAWQ more
> Hadoop native
> which interacts with other components more easily; secondly, ORC stores some
> meta info for
> query optimization, thus, it might potentially outperform two native formats
> (i.e., AO, Parquet) if it
> is available.
> The implementation can be based on the framework proposed in HAWQ-786.
