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