Jesus Camacho Rodriguez commented on HIVE-13068:
------------------------------------------------
Btw, we already needed to do something similar with PPD: we needed to create
SimplePredicatePushDown (HIVE-11865).
I will add comments to {{SimpleConstantReduction}} to clarify its coverage: I
just realized I did not do that.
