I'm trying to understand how celery works
In my django application in tasks.py
file I have created one task:
@celery.shared_task(default_retry_delay=2 * 60, max_retries=2)
def my_task(param1, param2):
# There are some operations
I call this task by using this code:
my_task.delay(param1, param2)
Inside of this my_task
there is one condition where this task should be started again but after one minute delay
I have found that there are some kind of ETA and countdown for tasks, but their examples are only with apply_async
Is it possible to use some kind countdown for delay
?
From basic part of celery Calling documentation
delay(*args, **kwargs)
Shortcut to send a task message, but doesn’t support execution options.
So delay is clearly convenient, but if you want to set additional execution options you have to use apply_async.
As documentation states delay
cannot be used with additional options set so you should just convert your call into apply_async
If you want to add execution options, the docs suggest you use a signature. e.g:
my_task.s(arg1, arg2).apply_async(countdown=60)
