Hi, Andrew,
Partition pruning for ORC is not addressed in PIG-3558. We will need
to do partition pruning for both ORC and Parquet in a new ticket.
Curently there is no interface to deal with this kind of pushdown
(LoadMetadata.setPartitionFilter push the filter to loader, but remove
the filter statement, for ORC/Parquet, filter is a hint, and we need
to do the filter again in Pig even it is pushed to loader), we will
need to define a new interface for that. You are welcome to initiate
the work. I know Aniket is also interested in doing that, so be sure
the talk with him about this work.
