dejankrak-db commented on PR #17918: URL: https://github.com/apache/iceberg/pull/17918#issuecomment-6069474879
The Parquet and ORC format rows require the reserved field IDs on the sub-fields. Is an Iceberg reader expected to resolve the sub-fields by ID only, or may it fall back to the sub-field names when the IDs are absent? Delta writes the IDs only when column mapping is enabled, and resolves the sub-fields by name otherwise, so it matters which data files a reader must accept. -- This is an automated message from the Apache Git Service.
