    Description

      As for now, PXF has HiveORC format which supports reading ORC files with leveraging ORC's file advantages(column projections, predicate push-downs).
      The only drawback of this profile - it still operates on a single row. So the idea is to implement a profile for reading ORC files, but operate on batches of rows, which supposed to be faster on reading and resolution phases.
