> I think a good first step would be figuring out how to abstract out the partition columns so that the existing ListingTable can work without any special code in core. I agree -- this would make a lot of sense. Maybe we could do something like pul `PartitionColumnProjector` out of `FileStream`: https://github.com/apache/datafusion/blob/3e086643ec79a01bb9614f2a3ab2d580a011171c/datafusion/datasource/src/file_stream.rs#L61-L62 And then making another stream wrapper that did the projecting ```rust /// Adds partitoning columns to an inner stream pub struct PartitionColumnStream<S> { pc_projector: PartitionColumnProjector, inner: S } ``` 🤔 -- This is an automated message from the Apache Git Service.
