      Description

      This issues was introduced with the change to serialize keys (vs whole rows) when partitioning (see HPCC-13791).

      The LHS keys are serialized to the slaves to partition the RHS, but if n LHS key serializer was generated, the code default to use the RHS compare() operator, when it should have used the LHS compare().
