Relevant discussion: https://github.com/apache/calcite/pull/784#discussion_r245797826

It looks like all the subsets is not a valid option.

> 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 the rule wants the whole subset, we just provide it
>             successors = ImmutableList.of(subset);

>             successors = subset.getRelList();
