--------------------------------------
Summary: Trigger rules for existing RelSubset when it becomes
delivered
Key: CALCITE-3966
URL: https://issues.apache.org/jira/browse/CALCITE-3966
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Haisheng Yuan
Fix For: 1.23.0
Existing RelSubset may be first created by parent trait request, so its state
is required. But when there is a new RelNode in the same RelSet can deliver the
same traitset, we mark the subset as derived/delivered too, in which case, we
should fire rule for the subset too.
