[jira] [Created] (CALCITE-4819) SemiJoin operator is not skipped in materialized view-based rewriting algorithm

Jesus Camacho Rodriguez created CALCITE-4819:
------------------------------------------------

             Summary: SemiJoin operator is not skipped in materialized view-based rewriting algorithm
                 Key: CALCITE-4819
                 URL: https://issues.apache.org/jira/browse/CALCITE-4819
             Project: Calcite
          Issue Type: Bug
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


This had been solved in CALCITE-2277 but apparently it was broken in CALCITE-2696 (MaterializedViewRelOptRulesTest.testJoinMaterialization11 result was modified assuming the change was correct). The rewriting algorithm does not support semijoin so this can lead to incorrect results.
