Getting Started 23 Celery Documentation consume tasks from. The worker can be told to consume from several queues at once, and this is used to route messages to specific workers as a means for Quality of Service, separation of concerns, and prioritization supports simple routing where messages are sent to named queues. The task_routes setting enables you to route tasks by name and keep everything centralized in one location: app.conf.update( task_routes = {
