Laljo John Pullokkaran commented on HIVE-11865:
-----------------------------------------------
[~jcamachorodriguez] SimplePredicatePushDown seems to be brute force and could
be refined.
SimpleFilterPPD shouldn't it check for DPP also. Now it seems like it would
process always.
Also SimplePredicatePushDown would re evaluate predicates that might have been
evaluated before and deemed unfit for push down.
This is not ideal.
