> Using IS NOT DISTINCT FROM as an equi condition in HashJoin produced
> incorrect results under the Enumerable convention. So in CALCITE-6904 , IS
> NOT DISTINCT FROM was treated as a non-equi condition.
> This work will fix the incorrect execution behavior and support IS NOT
> DISTINCT FROM as an equi condition of HashJoin.
