[C++][Compute] Support SimplifyWithGuarantee(is_null(foo), is_valid(foo))

    XMLWordPrintableJSON

Details

    Description

      Simplifying a predicate using is_null with a guarantee using invert(is_null()) doesn't lead to any simplification.

      Once supported, tests should be added for Datasets to exercise row group filtering (and to generate the necessary clauses from statistics).
