Setting Universal Format (UniForm) table properties not possible

[HectorPascual]

Description

I'd like to know whether it's possible to set the table properties required to have UniForm in delta tables created through delta-rs.

https://docs.delta.io/latest/delta-uniform.html

I've given it a few attempts with the python interface for delta-rs and also through Polars, but I've been unable to create a table with the properties :

"delta.enableIcebergCompatV2": "true",
"delta.universalFormat.enabledFormats": "iceberg"

Attempting to create a table with above properties results in the following error below :

DeltaError: Kernel: Generic delta kernel error: Error parsing property 'delta.enableIcebergCompatV2':'true'

Code for reproducing :

from deltalake import DeltaTable, Field, Schema


_default_table_properties: dict[str, str] = {
        "delta.enableIcebergCompatV2": "true",
        "delta.universalFormat.enabledFormats": "iceberg"
}

DeltaTable.create(
    table_uri='.',
    schema=Schema([Field("x", "integer")]),
    mode="overwrite",
    name='test',
    configuration=_default_table_properties,
)

I also tested creating the table and setting the propeties later but same error was thrown :

dt.alter.set_table_properties(_default_table_properties)

Environment

Python 3.12
DeltaLake 0.24.0

Once we switch to kernel-rs we can support parsing these (not sure though whether kernel-rs supports it further than that)
