Subject [jira] [Commented] (HIVE-4642) Implement vectorized RLIKE and REGEXP filter expressions
Date Wed, 02 Oct 2013 04:58:28 GMT


Jitendra Nath Pandey commented on HIVE-4642:

+1 for the patch.
However, the vectorization work is now committed to trunk. Please rebase the patch against
trunk. All vectorization work is now happening directly on trunk.
