Sergey Shelukhin commented on HIVE-5391:
----------------------------------------
Discussed out of bounds... summary: the same predicates as for normal reading;
ORC currently only uses predicates during row-group loading, so no
vectorization specific code should be necessary during row processing.
> make ORC predicate pushdown work with vectorization
