[jira] [Created] (CALCITE-3916) Apply rules bottom up by RelSet

Haisheng Yuan created CALCITE-3916:
--------------------------------------

             Summary: Apply rules bottom up by RelSet
                 Key: CALCITE-3916
                 URL: https://issues.apache.org/jira/browse/CALCITE-3916
             Project: Calcite
          Issue Type: Improvement
          Components: core
            Reporter: Haisheng Yuan


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.
