Ruben Q L updated CALCITE-5679:
-------------------------------
Description:
Minor optimization:
{{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).
