  Celery is an open-source distributed task queue for Python. It allows you to run
  tasks asynchronously in the background, enabling scalable distributed systems
  with support for multiple message brokers (RabbitMQ, Redis, Amazon SQS) and
  result backends. Celery provides a rich set of Python programming APIs for
  defining tasks, composing workflows, scheduling periodic work, executing on
  workers, and monitoring execution.
