Subject Re: Merge vectorization branch to trunk
Date Mon, 09 Sep 2013 17:50:09 GMT
Hi Brock,
   I will merge latest trunk to the branch and run all the tests again, and
provide you the run time difference. Trunk has moved ahead since the last
merge, therefore test results are a bit stale right now.

  No new dependencies have been added.

  Yes, there is boolean hive.vectorized.execution.enabled flag. If it is
false, vectorization optimization is completely ignored. By default, we
intend to keep it false for now, so that users who don't care about
vectorization don't have to change anything.
