[jira] [Created] (CALCITE-4952) Enable use of RelMetadataQuery using a simplistic & slow proxy path

Jacques Nadeau created CALCITE-4952:
---------------------------------------

             Summary: Enable use of RelMetadataQuery using a simplistic & slow proxy path
                 Key: CALCITE-4952
                 URL: https://issues.apache.org/jira/browse/CALCITE-4952
             Project: Calcite
          Issue Type: Improvement
          Components: core
            Reporter: Jacques Nadeau
            Assignee: Jacques Nadeau


As part of working on CALCITE-4882 and CALCITE-4928, it became clear that there should be a simple, non-janino implementation of RelMetadataQuery internals to help with debugging. I'm not sure when/how but as of right now the Reflective handlers can't be used with RelMetadataQuery without also using Janino.
