[jira] [Created] (BEAM-12010) CalcMergeRule should not merge BeamCalcRel and BeamZetaSqlCalcRel.

Kyle Weaver created BEAM-12010:
----------------------------------

             Summary: CalcMergeRule should not merge BeamCalcRel and BeamZetaSqlCalcRel.
                 Key: BEAM-12010
                 URL: https://issues.apache.org/jira/browse/BEAM-12010
             Project: Beam
          Issue Type: Improvement
          Components: dsl-sql-zetasql
            Reporter: Kyle Weaver
            Assignee: Kyle Weaver


Once we implement Calc splitting, CalcMergeRule will attempt to merge Calcs back together, which defeats the purpose of splitting them in the first place. We will need to narrow the merge conditions, to prevent incompatible Calcs from being merged.
