I have a task that I need to run asynchronously from the web page that triggered it. This task runs rather long, and as the web page could be getting a lot of these requests, I'd like celery to only run one instance of this task at a given time.
Is there any way I can do this in Celery natively? I'm tempted to create a database table that holds this state for all the tasks to communicate with, but it feels hacky.
