The use case is simple. I want to run a pipeline upto a dateset, but I don't want to write it anywhere. The

session.run

only returns an empty dict, and from what I understand, only datasets with some catalog issues are returned. from the session.run docstring:

Returns:
    Any node outputs that cannot be processed by the ``DataCatalog``.
    These are returned in a dictionary, where the keys are defined
    by the node outputs.
