Can we introduce `state_fields` and `fields` for `AggregateUDFImpl`. We can see that types in `AggregateUDFImpl` are for building fields, why not just return fields directly, we can not only define the types but also the `field name` and `is_nullalbe`. https://github.com/apache/arrow-datafusion/blob/e337832946fc69f6ceccd14b96a071cc2cd4693d/datafusion/physical-plan/src/udaf.rs#L86-L106 -- This is an automated message from the Apache Git Service.
