Lei Chang updated HAWQ-864:
---------------------------
Description:
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.
