Ruilong Huo closed HAWQ-864. ---------------------------- > 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: 2.5.0.0 > > > 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. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
