Subject [jira] [Commented] (HIVE-3585) Integrate Trevni as another columnar oriented file format
Date Tue, 13 Nov 2012 21:10:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13496546#comment-13496546

He Yongqiang commented on HIVE-3585:
------------------------------------

Although it is so similar to RCFIle, i did not see any reference to RCFile in its doc. I assume
that will help avoid confusion for its users. But as part of Hive, if we got two formats that
are so similar to each other, the confusion will be thrown to all hive users.

SerDe,seems fastutil is a good choice.the shark project use fastutil library as columnar serde
library but it seems too large (almost 15m) for just a few primitive array collection.
