你能强制芹菜计划任务立即在apply_sync上运行吗？

Question

I have a scheduled task on Celery which runs after every three minutes. However, in some cases I'd want to run the task immediately when a high priority task comes in.

Eg You have a schedule to send batch emails every 3 minutes. However, when a high priority email comes in, I'd want to call send_email.apply_async() and run it immediately and send that specific high priority email only and exit.

What I've noticed is that when I call send_email.apply_async(kwargs=hig_priority_email_details) , I notice that it is not being executed immediately and its like its being sent to run after the 3 minutes. What could I be missing?

The scheduled task:

'engine.app_engine_v1_0.send_email.run-every-180-seconds': 
    {'task': 'engine.app_engine_v1_0.send_email',
     'schedule': timedelta(seconds=180),
     'kwargs': {'no_of_emails':60000, 'lock_expire':5, 'skip_lock':False}
     },

Answer 1

I had not ran the .delay() method which Celery offers for such a while that I forgot about it. Its explained in the Celery Basics guide . Its a Shortcut to send a task message, but it does not support execution options.

So in this case, all I needed to do was call send_email.delay(**high_priority_email_details) and it will be ran immediately.
