django-celery is a Celery integration app for the Django framework.
django-celery provides Celery integration for Django; Using the Django ORM and cache backend for storing results, autodiscovery of task modules for applications listed in "INSTALLED_APPS", and more.
Celery is a task queue/job queue based on distributed message passing. It is focused on real-time operation, but supports scheduling as well.
The execution units, called tasks, are executed concurrently on a single or more worker servers. Tasks can execute asynchronously (in the background) or synchronously (wait until ready).
Celery is already used in production to process millions of tasks a day.
Celery is written in Python, but the protocol can be implemented in any language. It can also 'operate with other languages using webhooks'.
The recommended message broker is `RabbitMQ`_, but support for 'Redis' and databases ('SQLAlchemy' / 'Django') is also available.
