> RuleMatchVisualizer should merge sets when the planner detects their
> equivalence
> --------------------------------------------------------------------------------

> Key: CALCITE-6886

> Project: Calcite
> Issue Type: Improvement
> Reporter: Thomas Rebele
> Priority: Minor
> Attachments: CALCITE-6886.png
>
>
> If the planner merges two sets when they have been determined to be
> equivalent, the RuleMatchVisualizer does not merge them in the visualization.
> Instead, it keeps the second set with the subsets but no RelNode inside.
> To reproduce the issue, apply the RuleMatchVisualizer to
> VolcanoPlannerTest.testSetMergeMatchSubsetRule().
