[jira] [Created] (BEAM-10595) Remove rules that not work well with Java UDF

Rui Wang created BEAM-10595:
-------------------------------

             Summary: Remove rules that not work well with Java UDF
                 Key: BEAM-10595
                 URL: https://issues.apache.org/jira/browse/BEAM-10595
             Project: Beam
          Issue Type: Improvement
          Components: dsl-sql-zetasql
            Reporter: Rui Wang
            Assignee: Rui Wang


In order to support Java UDF, we need both BeamZetaSqlCalcRel and BeamCalcRel. It is 
because BeamZetaSqlCalcRel can execute ZetaSQL built-in functions while BeamCalcRel
can execute UDFs. So during planning, we expect both Filter and Project are converted to
 a Calc before merging with other Projec/Filter/Calc. Thus we should not add FilterCalcMergeRuleand ProjectCalcMergeRule.
