I guess I was expecting that the Column expression would preserve field metadata, and all other expressions would continue to do what they currently do. Part of the challenge is that ProjectionExec can be used for more than just basic column projection due to its formulation in terms of expressions. This isn't necessarily a problem, but I'd just like to be able to project a schema without losing field metadata - as within IOx we use this for additional field type information -- This is an automated message from the Apache Git Service.
