> I think a good approach might be to have the cast part of the logical planner, so the join expression becomes in the form `col1::TEXT = col2 AND col2::`. That shouldn't be really very join specific > > I believe we should already have most of the logic there for casting to a common type for expressions. Yes, that is something we discussed with @alamb, that other sql engines have cast as part of planner if join arms are not the same datatype but still castable. So what your idea @Dandandan, to try move cast into the planner? -- This is an automated message from the Apache Git Service.
