----------------------------------
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).
