wgtmac opened a new pull request, #35499: URL: https://github.com/apache/arrow/pull/35499
### Rationale for this change Apache Orc has a per column attribute map and Apache Iceberg depends on this to encode its field metadata. However, the C++ Orc adapter does not know it which makes it difficult to support pyarrow and pyiceberg. ### What changes are included in this PR? Both reader and writer support Orc attributes conversion from/to arrow field metadata. ### Are these changes tested? Added two test cases to make sure the Orc adapter can preserve the attributes well. ### Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service.
