[jira] [Created] (IMPALA-11274) CNF Rewrite causes a regress in join node performance

Qifan Chen created IMPALA-11274:
-----------------------------------

             Summary: CNF Rewrite causes a regress in join node performance
                 Key: IMPALA-11274
                 URL: https://issues.apache.org/jira/browse/IMPALA-11274
             Project: IMPALA
          Issue Type: Bug
          Components: Frontend
            Reporter: Qifan Chen


It appears that cnf rewrite can generate more predicates and presumably cause the same query to execute slower.
