Haisheng Yuan created CALCITE-3889: -------------------------------------- Summary: Add apply(Mappings.Mapping) to RelTrait and RelTraitSet Key: CALCITE-3889 URL: https://issues.apache.org/jira/browse/CALCITE-3889 Project: Calcite Issue Type: Improvement Components: core Reporter: Haisheng Yuan
RelTrait Collation, Distribution have key indices, when we pass down the traitset to child or propagate to parent operator, we have to remap these keys. It would be nice to have {{apply(Mappings.Mapping)}} on RelTrait and RelTraitSet. RelDistribution already has the method, but we may want it on every RelTrait except Convention. -- This message was sent by Atlassian Jira (v8.3.4#803005)
