::DeveloperApi::
A BaseRelation that can eliminate unneeded columns and filter using selected
predicates before producing an RDD containing all matching tuples as Row objects.
The pushed down filters are currently purely an optimization as they will all be evaluated
again. This means it is safe to use them with methods that produce false positives such
as filtering partitions based on a bloom filter.
