----------------------------------
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.
