work across threads or machines. A task queue’s input is a unit of work called a task. Dedicated worker processes constantly monitor task queues for new work to perform. Celery communicates via messages workers. To initiate a task, a client adds a message to the queue, which the broker then delivers to a worker. A Celery system can consist of multiple workers and brokers, giving way to high availability and second/minute/hour, or how long a task can be allowed to run, and this can be set as a default, for a specific worker or individually for each task type.
