[jira] [Created] (CALCITE-2942) Materialized view rewriting logic instantiates RelMetadataQuery each time the rule is triggered

Jesus Camacho Rodriguez created CALCITE-2942:
------------------------------------------------

             Summary: Materialized view rewriting logic instantiates RelMetadataQuery each time the rule is triggered
                 Key: CALCITE-2942
                 URL: https://issues.apache.org/jira/browse/CALCITE-2942
             Project: Calcite
          Issue Type: Improvement
            Reporter: Jesus Camacho Rodriguez


Performance penalty is similar to the one described in CALCITE-1812. An instance may be available in the cluster, hence we can use it; this is just an addendum to CALCITE-1812.
