Subject Hive external indexes incorporation into Hive CBO
Date Thu, 21 Apr 2016 10:02:06 GMT

As we have discussed this few times, Hive external indexes (as opposed to
Store Indexes in ORC tables) are there but are not currently utilised.

For Hive to be effective it needs to use these indexes for a variety of
reasons and the CBO should leverage these indexes.

I am not sure how far we are down the road with Work In Progress on this.
However, I am happy to help with this.
