Question

I’m starting with Celery (integrated with Django).

I would like to schedule a task, every 5 minutes. This task can have a parameter which is the last task execution result (it acts as a context).

I found how to chain and schedule tasks but I can’t find the right way to provide this “context” to the next task.

Sorry if I missed something in the Celery’s documentation..

Thanks for your help,
Arnaud.

I think it would be better to use some persistent storage for this problem. But you can run delayed tasks in celery using eta or countdown parameters:

The ETA (estimated time of arrival) lets you set a specific date and
time that is the earliest time at which your task will be executed.
countdown is a shortcut to set eta by seconds into the future.
