    Description

      Commit c0f3727 added an optimization to push predicate evaluation into the CFile decoders without fully materializing the contents of each cblock. It did this with dictionary-encoded blocks, but the optimization can be applied to any other encoding types too.

      KUDU-736 also notes that we may be able to apply some predicates on bitshuffled data.
