zeroshade opened a new pull request, #293: URL: https://github.com/apache/arrow-go/pull/293
### Rationale for this change Discovered while fixing https://github.com/apache/iceberg-go/issues/309 we didn't correctly propagate the field-id metadata to children of List or Map fields, only structs. ### What changes are included in this PR? A new MapType creator for constructing MapTypes from arrow fields for the Key and Items for easier construction, and fixing the `pqarrow` schema manifest creation to correctly propagate the child metadata field IDs for the children. ### Are these changes tested? Unit test is added. ### Are there any user-facing changes? Usage of pqarrow reading List/Map typed fields will now correctly contain the `PARQUET:field_id` metadata key in the schema produced. -- This is an automated message from the Apache Git Service.
