> I wonder if we could make type coercion part of "simplify_expressions" 🤔 that way it would always be called at the appropriate time 🤔 I think it is not a good way do this. `simplify_expressions` rule can be called many times, but the `type_coercion` just can do only once. We should do the `type_coercion` before all operation and optimization. I think it is most important: the right data type system is the base of the all things I submit a issue to talk about this thing https://github.com/apache/arrow-datafusion/issues/3582 @alamb -- This is an automated message from the Apache Git Service.
