Russell Melick commented on HIVE-1644:
--------------------------------------
We also spoke about changing the re-entrant query construction to live within
the IndexHandler class. Unfortunately, the Index object can only give us
access to the Handler's name as a string, not an instance of it
(IndexWhereProcessor.rewriteForIndex). I looked through the codebase some to
figure out how classes are loaded from strings, and found several examples of
using Class.forName(...). Any suggestions here?
> use filter pushdown for automatically accessing indexes

> HIVE-1226 provides utilities for analyzing filters which have been pushed
> down to a table scan. The next step is to use these for selecting available
> indexes and generating access plans for those indexes.
