Temporary queue made in Celery

Question

I am using Celery with RabbitMQ. Lately, I have noticed that a large number of temporary queues are getting made.

So, I experimented and found that when a task fails

Answer 1

amqp backend creates a new queue for each task. If you want to avoid it, you can use rpc backend which keeps results in a single queue.

In your config, set

CELERY_RESULT_BACKEND = 'rpc'
CELERY_RESULT_PERSISTENT = True

You can read more about this on celery docs.
