You're right to be cautious about using Celery with Redis on Windows. Historically, Celery on Windows has had some compatibility issues, especially with its default prefork concurrency model, which doesn't play well with Windows due to how multiprocessing works on that platform. This is especially relevant if you're using Celery 4.x, which relies heavily on multiprocessing and may cause synchronization problems or poor performance on Windows.

If you need something simpler than Celery for small tasks like CSV uploads: multiprocessing or Django Q would be good choices, especially if you're looking for something that doesn’t require as much setup or infrastructure.
