> 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.
