>             Project: Calcite
>          Issue Type: Improvement
>          Components: core

> Apply rules by leaf RelSet -> root RelSet order. For every RelNode in a RelSet, rule is matched and applied sequentially. No RuleQueue and DeferringRuleCall is needed anymore. This will make space pruning and rule mutual exclusivity check possible.
> Rule that use AbstractConverter as operand is an exception, to keep backward compatibility, this kind of rule still needs top-down apply.
> This should be done after CALCITE-3896.
