Redis task queue for Python 3 heavily inspired by Celery and RQ.

Distinctive features:

• Threaded and asyncio workers
• At-least-once or at-most-once delivery per task
• Periodic tasks without an additional process
• Concurrency limits on queued jobs
• Scheduling of tasks in batch
• Integrations with Flask, Django, Logging, Sentry and Datadog <https://spinach.readthedocs.io/en/stable/user/integrations.html>_
• Embeddable workers for easier testing
• See design choices <https://spinach.readthedocs.io/en/stable/user/design.html>_ for more details

Quickstart

Install Spinach with pip::

pip install spinach

Create a task and schedule a job to be executed now:

.. code:: python

from spinach import Engine, MemoryBroker

spin = Engine(MemoryBroker())


@spin.task(name='compute')
def compute(a, b):
    print('Computed {} + {} = {}'.format(a, b, a + b))


# Schedule a job to be executed ASAP
spin.schedule(compute, 5, 3)

print('Starting workers, ^C to quit')
spin.start_workers()
