Tracking issue for pyiceberg changes to achieve compatibility

[c-thiel]

Currently there are a few issues with pyiceberg compatibility. We should open issues for those:

• pyiceberg prepends warehouse-name to namespaces. This is against the Iceberg-Rest spec. https://github.com/apache/iceberg-python/blob/20b7b5339a1a0ab59d884c7d042c4bc96a166b11/pyiceberg/catalog/rest.py#L464
• If warehouse name is None, the first segment of Namespaces is missing: https://github.com/apache/iceberg-python/blob/20b7b5339a1a0ab59d884c7d042c4bc96a166b11/pyiceberg/catalog/rest.py#L356 (notice [1:] ...)
• FSSPEC does not honor "s3.signer.uri" property: https://github.com/apache/iceberg-python/blob/20b7b5339a1a0ab59d884c7d042c4bc96a166b11/pyiceberg/io/fsspec.py#L75
• Only vended credentials are supported even though remote signing via fsspec is also possible

Compatability will come with pyiceberg 0.7.0

It looks like pyiceberg 0.7.0 release it about to be cut, but without apache/iceberg-python#742.

Thanks for thinking about us. If we have to we can build around then on the catalog side as well. Glad that pyiceberg is running the extra round to harmonize across catalogs.

All pyiceberg-issues solved - thanks folks! Last one on our side for remote signing: https://github.com/hansetag/iceberg-catalog/pull/212
