Stamatis Zampetakis commented on CALCITE-4003:
----------------------------------------------
I agree that we should solve these kind of problems. As we said in other
discussions most likely this rule should only match logical operators.
Nevertheless, if people want to write cross convention rules we shouldn't
remove this possibility.
> In MaterializationTest, FilterProjectTransposeRule matches with logical and
> physical convention
