[jira] [Created] (CALCITE-5679) HepPlanner#buildFinalplan: do not clear metadata cache if RelNode has not changed

Ruben Q L created CALCITE-5679:
----------------------------------

             Summary: HepPlanner#buildFinalplan: do not clear metadata cache if RelNode has not changed
                 Key: CALCITE-5679
                 URL: https://issues.apache.org/jira/browse/CALCITE-5679
             Project: Calcite
          Issue Type: Improvement
          Components: core
            Reporter: Ruben Q L
             Fix For: 1.35.0


{{HepPlanner#buildFinalplan}} clears the metadata cache info of the impacted RelNode after replacing its inputs, but in the cases where the RelNode does not change (e.g. when it has no inputs) this clear cache should not be necessary (unless I'm missing something).
