This is what we’re talking about by the way https://github.com/kedro-org/kedro-plugins/pull/95/files And you can use the pandas equivalent to see how we did that: https://kedro.readthedocs.io/en/stable/_modules/kedro/extras/datasets/pandas/generic_dataset.html#GenericDataSet The bit that’s important is that we included an exclusion list of

NON_FILE_SYSTEM_TARGETS

so we didn’t support writing in certain directions. With polars we could possibly do this dynamically and simply check what suffixes are available 🙂
