In a Celery task module, I have the following code: # someapp/tasks.py from celery import shared_task from celery . utils . log import get_task_logger logger = get_task_logger ( __name__ ) @shared_task () def foo (): logger . info ( 'Test output: %s' , u "测试中" ) I use the initd script here to run a Celery worker.

I know which task needs to run in what timezone when the task is being scheduled. Is it possible to specify a different timezone for each of the tasks?

I have been sending thousands of messages to the queue and they are being processed successfully and everything is working just fine. However, the number of messages in several rabbitmq queues are growing quite large (hundreds of thousands of items in the queue). The queues are named celeryev.[...] (see screenshot below). Is this appropriate behavior? What is the purpose of these queues and shouldn't they be regularly purged? Is there a way to purge them more regularly, I think they are taking up quite a bit of

I just configured my airflow.cfg file to use the CeleryExecutor , I pointed my sql_alchemy_conn to my postgresql database that's running on the same master node, I've set the broker_url to use AWS SQS (I didn't set the access_key_id or secret_key since it's running on an EC2-Instance it doesn't need those), and I've set the celery_result_backend to my postgresql server too. I saved my new airflow.cfg changes, I ran airflow initdb , and then I ran airflow scheduler

Let's see simple example below from myqueue import Queue @perodic_task(run_every=timedelta(minutes=1)) def process_queue(): queue = Queue() uid, questions = queue.pop() if uid is None: return job = group(do_stuff(q) for q in questions) job.apply_async() def do_stuff(question): try: ... except: ... raise As you can see in the example above, i use celery to run async task, but (since it's a queue) i need to do queue.fail(uid) in case of exception in do_stuff or queue.ack(uid) otherwise.
