I'm interested in this as well; however, I'm new to DataFusion development and I am not sure I have a handle on what the barriers are here (e.g., Is support for this blocked by lack of support in arrow-rs? Is there opposition to this on principle or is it just a matter of development time?). A few more (albeit geospatial) reasons to add support for this are (not-quite-merged!) support for spatial data in Iceberg and Parquet. As currently written, those proposals include type-level metadata (notably: the CRS), which would mean that reading Parquet files with those types would loose information. There are also other [Arrow canonical extension types](https://arrow.apache.org/docs/format/CanonicalExtensions.html) that have type-level metadata (which to my current reading, means that canonical extension types are not usable in DataFusion?). -- This is an automated message from the Apache Git Service.
