Answer 1

You need a function that the worker should run. Otherwise the worker would be quite unnecessary.

For example with the function the_tasks, you add it to the functions argument of the worker:

arq import Worker

async def the_task(ctx):
    print('running the task')
    return 42

w = Worker(functions=[the_task],
    redis_settings=WorkerSettings.redis_settings(),
    max_jobs=1000,
    keep_result_forever=True,
    job_timeout=86000,
    max_tries=1000)
w.run()
