> Thanks for working on this. The plan-visible CoerceSchemaExec approach looks good, and I like that it removes the schema restamping from UnionExec::execute() and InterleaveExec::execute() while keeping the coercion explicit in the plan. I wonder if instead of using an entirely new exec, we could use the existing ProjectionExec operator with Cast exprs? In theory it should already be capable of doing the schema tranformation (assuming the physical CastExpr can have a field -- not just a DataType) Thank you for follow up on this @dariocurr and @kosiew -- This is an automated message from the Apache Git Service.
