    # Celery workers handle background tasks (such file imports or federation
    # messaging). The more processes a worker gets, the more tasks
    # can be processed in parallel. However, more processes also means
    # a bigger memory footprint.
    # By default, a worker will span a number of process equal to your number
    # of CPUs. You can adjust this, by explicitly setting the --concurrency
    # flag:
    #   celery -A funkwhale_api.taskapp worker -l INFO --concurrency=4
