Subject [jira] [Updated] (CRUNCH-450) Adding ORC file format support in Crunch
Date Tue, 12 Aug 2014 21:50:13 GMT

     [ https://issues.apache.org/jira/browse/CRUNCH-450?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhong Wang updated CRUNCH-450:
------------------------------

    Description: 
This JIRA adds ORC (Optimized Row Columnar) file format support in Crunch. Three modes are
supported for ORC serialization/deserialization:
--
1) Orcs.orcs(): using OrcStructs as the deserialized objects to provide high performance
2) Orcs.reflects(): using Java reflection to support POJOs as the deserialized objects
3) Orcs.tuples(): using Crunch Tuples as the deserialized objects to leverage performance
and user-friendliness
