[jira] [Created] (CALCITE-1129) Extend JoinUnionTransposeRule to match Union instead of LogicalUnion

Vasia Kalavri created CALCITE-1129:
--------------------------------------

             Summary: Extend JoinUnionTransposeRule to match Union instead of LogicalUnion
                 Key: CALCITE-1129
                 URL: https://issues.apache.org/jira/browse/CALCITE-1129
             Project: Calcite
          Issue Type: Improvement
          Components: core
            Reporter: Vasia Kalavri
            Assignee: Julian Hyde
            Priority: Minor


The {{JoinUnionTransposeRule}} is fired if one of the operands is a {{Union}}, but inside the {{onMatch()}} method, the code checks if one of the operands is an instance of {{LogicalUnion}}. External implementations would benefit from changing the rule to match {{Union}} instead.
