> General comment independent of this change: Do we really need `FilterCalcMergeRule` and `ProjectCalcMergeRule`? They look a bit redundant in the presence of `FilterToCalcRule` `ProjectToCalcRule` and `CalcMergeRule`. `FilterCalcMergeRule` and `ProjectCalcMergeRule` produce only `LogicalCalc` also, it can make further optimizations more difficult. -- This is an automated message from the Apache Git Service.
