Description

If I have a rule to match pattern with Filter-RelSubset, VolcanoPlanner only matches 1 RelSubset in the RelSet, instead of all the subsets.

         if (operand.getMatchedClass() == RelSubset.class) {
            // If the rule wants the whole subset, we just provide it
            successors = ImmutableList.of(subset);  
          } else {
            successors = subset.getRelList();
          }
