I want to make sure I'm not missing something that already exists; otherwise, hoping to get a quick thumbs up / thumbs down on a potential proposal before spending more time on it.
It would be nice to know what Iceberg schema a writer used (/assumed) when writing a DataFile. Oftentimes, this information is written into the parquet file's metadata, but it would be great if Iceberg provided this directly. A schema_id on DataFile would be nice, I think. Thanks, -Devin
