[jira] [Updated] (HAWQ-864) Support ORC as a native file format

     [ https://issues.apache.org/jira/browse/HAWQ-864?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
