twuebi opened a new pull request, #1599: URL: https://github.com/apache/iceberg-go/pull/1599
Arrow has no extension-to-extension cast kernel. Projecting a column whose file and requested types are the same named extension with differing parameters fails with "cast_extension has no kernel matching input types", e.g. geoarrow.wkb spelling the same CRS as an SRID vs. an authority code. The values already carry the extension's storage encoding, so rewrapping that storage in the requested type is zero-copy and correct; storage is cast only on a width mismatch, and the requested type stays authoritative. -- This is an automated message from the Apache Git Service.
