> 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.
