[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.
