Is it possible to have the mapping of the relation between arrow's DataType and `LogicalType` without `TypeRelation`? As long as there is only one `LogicalType` for each `arrow::DataType`, we can build up the mapping via `From/Into` conversion. > I was thining that a `DFSchema` could still wrap an arrow `Schema` but translate to `LogicalType` We can then easily get the `LogicalType` from `DataType` inside `Schema`. Is there any type mapping is not possible without `TypeRelation` 🤔 ? In other words, is there any `arrow::DataType` that can be mapped to more than one `LogicalType`? -- This is an automated message from the Apache Git Service.
