Kenneth Knowles updated BEAM-10595:
-----------------------------------
Status: Open (was: Triage Needed)
> 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
> Priority: P2
>
> 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.
