[jira] [Created] (BEAM-12009) Implement Calc splitting.

Kyle Weaver created BEAM-12009:
----------------------------------

             Summary: Implement Calc splitting.
                 Key: BEAM-12009
                 URL: https://issues.apache.org/jira/browse/BEAM-12009
             Project: Beam
          Issue Type: Sub-task
          Components: dsl-sql-zetasql
            Reporter: Kyle Weaver
            Assignee: Kyle Weaver


In order to use Java UDFs along with ZetaSQL built-in functions, we will need the ability to split a single LogicalCalc into multiple Beam Calc nodes (BeamCalcRel and/or BeamZetaSqlCalcRel). We might use [CalcRelSplitter|https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/rel/rules/CalcRelSplitter.java] as a starting point.
