To initiate a task a client puts a\nmessage on the queue, the broker then delivers the message to a worker.\n\nA Celery system can consist of multiple workers and brokers, giving way\nto high availability and horizontal scaling.\n\nCelery is written in Python, but the protocol can be implemented in any\nlanguage. In addition to Python there's node-celery_ for Node.js,\na `PHP client`_, `gocelery`_, gopher-celery_ for Go, and rusty-celery_ for Rust.\n\nLanguage interoperability can also be achieved by using webhooks\nin such a way that the client enqueues an URL to be requested by a worker.\n\n.. _node-celery: https://github.com/mher/node-celery\n.. _`PHP client`: https://github.com/gjedeer/celery-php\n.. _`gocelery`: https://github.com/gocelery/gocelery\n.. _gopher-celery: https://github.com/marselester/gopher-celery\n.. _rusty-celery: https://github.com/rusty-celery/rusty-celery\n\nWhat do I need?\n===============\n\nCelery version 5.5.x runs on:\n\n- Python (3.8, 3.9, 3.10, 3.11, 3.12, 3.13)\n- PyPy3.9+ (v7.3.12+)\n\n\nThis is the version of celery which will support Python 3.8 or newer.\n\nIf you're running an older version of Python, you need to be running\nan older version of Celery:\n\n- Python 3.7: Celery 5.2 or earlier.\n- Python 3.6: Celery 5.1 or earlier.\n- Python 2.7: Celery 4.x series.\n- Python 2.6: Celery series 3.1 or earlier.\n- Python 2.5: Celery series 3.0 or earlier.\n- Python 2.4: Celery series 2.2 or earlier.\n\nCelery is a project with minimal funding,\nso we don't support Microsoft Windows but it should be working.\nPlease don't open any issues related to that platform.\n\n*Celery* is usually used with a message broker to send and receive messages.\nThe RabbitMQ, Redis transports are feature complete,\nbut there's also experimental support for a myriad of other solutions, including\nusing SQLite for local development.\n\n*Celery* can run on a single machine, on multiple machines, or even\nacross datacenters.\n\nGet Started\n===========\n\nIf this is the first time you're trying to use Celery, or you're\nnew to Celery v5.5.x coming from previous versions then you should read our\ngetting started tutorials:\n\n- `First steps with Celery`_\n\n    Tutorial teaching you the bare minimum needed to get started with Celery.\n\n- `Next steps`_\n\n    A more complete overview, showing more features.\n\n.. _`First steps with Celery`:\n    https://docs.celeryq.dev/en/stable/getting-started/first-steps-with-celery.html\n\n.. _`Next steps`:\n    https://docs.celeryq.dev/en/stable/getting-started/next-steps.html\n\n You can also get started with Celery by using a hosted broker transport CloudAMQP. The largest hosting provider of RabbitMQ is a proud sponsor of Celery.\n\nCelery is...\n=============\n\n- **Simple**\n\n    Celery is easy to use and maintain, and does *not need configuration files*.\n\n    It has an active, friendly community you can talk to for support,\n    like at our `mailing-list`_, or the IRC channel.\n\n    Here's one of the simplest applications you can make:\n\n    .. code-block:: python\n\n        from celery import Celery\n\n        app = Celery('hello', broker='amqp://guest@localhost//')\n\n        @app.task\n        def hello():\n            return 'hello world'\n\n- **Highly Available**\n\n    Workers and clients will automatically retry in the event\n    of connection loss or failure, and some brokers support\n    HA in way of *Primary/Primary* or *Primary/Replica* replication.\n\n- **Fast**\n\n    A single Celery process can process millions of tasks a minute,\n    with sub-millisecond round-trip latency (using RabbitMQ,\n    py-librabbitmq, and optimized settings).\n\n- **Flexible**\n\n    Almost every part of *Celery* can be extended or used on its own,\n    Custom pool implementations, serializers, compression schemes, logging,\n    schedulers, consumers, producers, broker transports, and much more.\n\nIt supports...\n================\n\n    - **Message Transports**\n\n        - RabbitMQ_, Redis_, Amazon SQS, Google Pub/Sub\n\n    - **Concurrency**\n\n        - Prefork, Eventlet_, gevent_, single threaded (``solo``)\n\n    - **Result Stores**\n\n        - AMQP, Redis\n        - memcached\n        - SQLAlchemy, Django ORM\n        - Apache Cassandra, IronCache, Elasticsearch\n        - Google Cloud Storage\n\n    - **Serialization**\n\n        - *pickle*, *json*, *yaml*, *msgpack*.\n        - *zlib*, *bzip2* compression.\n        - Cryptographic message signing.\n\n.. _`Eventlet`: http://eventlet.net/\n.. _`gevent`: http://gevent.org/\n\n.. _RabbitMQ: https://rabbitmq.com\n.. _Redis: https://redis.io\n.. _SQLAlchemy: http://sqlalchemy.org\n\nFramework Integration\n=====================\n\nCelery is easy to integrate with web frameworks, some of which even have\nintegration packages:\n\n    +--------------------+------------------------+\n    | `Django`_          | not needed             |\n    +--------------------+------------------------+\n    | `Pyramid`_         | `pyramid_celery`_      |\n    +--------------------+------------------------+\n    | `Pylons`_          | `celery-pylons`_       |\n    +--------------------+------------------------+\n    | `Flask`_           | not needed             |\n    +--------------------+------------------------+\n    | `web2py`_          | `web2py-celery`_       |\n    +--------------------+------------------------+\n    | `Tornado`_         | `tornado-celery`_      |\n    +--------------------+------------------------+\n    | `FastAPI`_         | not needed             |\n    +--------------------+------------------------+\n\nThe integration packages aren't strictly necessary, but they can make\ndevelopment easier, and sometimes they add important hooks like closing\ndatabase connections at ``fork``.\n\n.. _`Django`: https://djangoproject.com/\n.. _`Pylons`: http://pylonsproject.org/\n.. _`Flask`: https://flask.palletsprojects.com/\n.. _`web2py`: http://web2py.com/\n.. _`Bottle`: https://bottlepy.org/\n.. _`Pyramid`: https://docs.pylonsproject.org/projects/pyramid/en/latest/\n.. _`pyramid_celery`: https://pypi.org/project/pyramid_celery/\n.. _`celery-pylons`: https://pypi.org/project/celery-pylons/\n.. _`web2py-celery`: https://code.google.com/p/web2py-celery/\n.. _`Tornado`: https://www.tornadoweb.org/\n.. _`tornado-celery`: https://github.com/mher/tornado-celery/\n.. _`FastAPI`: https://fastapi.tiangolo.com/\n\n.. _celery-documentation:\n\nDocumentation\n=============\n\nThe `latest documentation`_ is hosted at Read The Docs, containing user guides,\ntutorials, and an API reference.\n\n.. _`latest documentation`: https://docs.celeryq.dev/en/latest/\n\n.. _celery-installation:\n\nInstallation\n============\n\nYou can install Celery either via the Python Package Index (PyPI)\nor from source.\n\nTo install using ``pip``:\n\n::\n\n\n    $ pip install -U Celery\n\n.. _bundles:\n\nBundles\n-------\n\nCelery also defines a group of bundles that can be used\nto install Celery and the dependencies for a given feature.\n\nYou can specify these in your requirements or on the ``pip``\ncommand-line by using brackets.
