Understand how Celery works by building a clone

I'm a newbie to background jobs and I have a question -

Whenever a user's action gets pushed to a background job how do you go about notifying the user about the status of the job?

Do you resort back to email or some kind of more complex websocket based solution?

I'm not quite thinking about long running jobs but more like the ones which take maybe 10 or 15 seconds. In the this kind of a scenario, wouldn't a simpler soliton be to just make the user wait? Maybe just show a spinner?

/me was really hoping this was going to be about the vegetable.

Me, too. I feel like I want my click back, damnit! :P

You may want to change _celery_ to _Celery_.

Ok, we've upgraded to C above. Good idea.
