dgvj-work opened a new pull request, #1241: URL: https://github.com/apache/arrow-go/pull/1241
### Rationale for this change The canonical Variant extension type name is `arrow.parquet.variant`. arrow-go still writes `parquet.variant`, which predates https://github.com/apache/arrow/pull/47456. That makes Variant IPC unreadable by other Arrow implementations, and vice versa. C++ already made this change in apache/arrow#49082. Fixes #1203 ### What changes are included in this PR? - `VariantType.ExtensionName()` now returns `arrow.parquet.variant` - Keep `parquet.variant` registered so older arrow-go IPC still deserializes as `VariantType` - Parquet schema conversion recognizes both names ### Are these changes tested? - `go test ./arrow/extensions` - `go test ./parquet/pqarrow -run 'TestConvertSchemaParquetVariant|TestShreddedVariantSchema'` ### Are there any user-facing changes? Yes — newly written IPC/Flight metadata uses `arrow.parquet.variant`. Existing `parquet.variant` data still reads.
