             Summary: SubQueryFilterRemoveRule failed to decorrelate subquery for TPCH q17
                 Key: CALCITE-3918
                 URL: https://issues.apache.org/jira/browse/CALCITE-3918

          Issue Type: Bug
          Components: core
            Reporter: Haisheng Yuan


Disable RelDecorrelator and run TpchTest.testQuery17(),  SubQueryFilterRemoveRule generates plan with Correlate, which is not expected.
