Rui Wang commented on BEAM-7146:
--------------------------------
[~sridharG]
This is the big feature I mentioned to you. A general code generator would be
very useful. Right now we cannot execute SELECT * FROM A JOIN B on A.col + 1 =
B.col. It is because code generation (thus function execution) is deeply
coupled with Projection (in BeamCalcRel). Within Join condition we have no way
to execution any operator (e.g +, -) or function.
> Code generator is accessible from all RelNode

> Priority: Major

> Right now code generation is used in Projection (in BeamCalcRel). However,
> code generation can be used in all places that might need to execute a
> function. Therefore, this JIRA propose to have a layer (called code
> generator) that could be used in other rels: join, aggregation, etc.
