Luigi on Windows
^^^^^^^^^^^^^^^^

Most Luigi functionality works on Windows. Exceptions:

- Specifying multiple worker processes using the ``workers`` argument for
``luigi.build``, or using the ``--workers`` command line argument. (Similarly,
specifying ``--worker-force-multiprocessing``). For most programs, this will
result in failure (a common sight is ``BrokenPipeError``). The reason is that
worker processes are assumed to be forked from the main process. Forking is
`not possible <https://docs.python.org/dev/library/multiprocessing.html#contexts-and-start-methods>`_
on Windows.
- Running the Luigi central scheduling server as a daemon (i.e. with ``--background``).
Again, a Unix-only concept.
