> Key: CALCITE-5679
> URL: https://issues.apache.org/jira/browse/CALCITE-5679
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Reporter: Ruben Q L
> Assignee: Ruben Q L
> Priority: Minor
> Labels: pull-request-available
> Fix For: 1.35.0

>
> 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).
