[GitHub] [iceberg] Fokko commented on issue #7979: Pyiceberg StaticTable use the last metadata json URL when the full path is not provided

Thanks for raising this, I can see how this is confusing. How the table is written? Ideally, this information comes from a catalog. When using the HDFS, there is a `version-hint.txt` that could be used, but this is [optional](https://github.com/apache/iceberg/issues/1496).
Some context. By design, Iceberg forbids list operations on the filesystem. This is because Iceberg is object-store-oriented, and list operations are expensive. S3 and GCS don't have a notion of a directory, and if you do a list, it might return a lot of files (which will be fetched paged, so this will result in many requests).
