From what I understand as someone who's currently learning and using Iceberg, the add_files procedure is designed to quickly register external Parquet files into an Iceberg table, so it doesn't deeply parse the file contents. Instead, it only records basic information in the manifest, which is likely why column-level metadata like lower/upper bounds isn't included. I'm not a maintainer so I can't say for sure, but this could potentially be an area for improvement in the future — especially for optimizing filtering performance or catalog introspection. -- This is an automated message from the Apache Git Service.
