Subject [jira] [Commented] (HIVE-5538) Turn on vectorization by default.
Date Tue, 03 Jun 2014 01:10:02 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14016115#comment-14016115

Edward Capriolo commented on HIVE-5538:
---------------------------------------

To be clear we need a long term solution to rigorously test both code paths. Defaulting vectorization
on could lead to rot in non vectorized code paths.

> Turn on vectorization by default.

>   Vectorization should be turned on by default, so that users don't have to specifically
enable vectorization. 
>   Vectorization code validates and ensures that a query falls back to row mode if it
is not supported on vectorized code path.
