Getting Started Scheduling Tasks with Celery
Introduction to Celery
The purpose of Celery is to allow you to run some code later, or regularly according to a schedule.
Why might this be useful? Here are a couple of common cases.
First, suppose a web request has come in from a user, who is waiting for the request to complete so a new page can load in their browser. Based on their request, you have some code to run that’s going to take a while (longer than the person might want to wait for a web page), but you don’t really need to run that code before responding to the web request. You can use Celery to have your long-running code called later, and go ahead and respond immediately to the web request.
