xndai opened a new pull request #1543: [Calcite-3455] Redundant rule firing for both logical and physical nodes
URL: https://github.com/apache/calcite/pull/1543
 
 
   For ProjectMergeRule, EnumerableLimitRule and SortRemoveConstantKeysRule, once they are done with the transformation on logical nodes, there's no need to fire these rules on physical nodes again. So limit these rule matching to be with logical nodes only. This can noticeably speed up optimization latency.
