Django async vs Celery

Django itself does not determine whether it runs in one or more threads . This is the job of the server running Django. The development server used to be single-threaded, but in recent versions it has been made multithreaded.

WSGI handles requests synchronously . When requests come in, they are processed sequentially or one after the other. They have to wait until the one before it finishes before switching to a new task.

First, to dispel a misconception about signals, they are not executed asynchronously . There is no background thread or worker to execute them. Like most of Django, they are fully “synchronous”.

Django itself is synchronous . each HTTP request will be handled completely synchronously. However you have extensions like django-channels ( https://github.com/django/channels ) , which are asynchronous and are intended for web sockets / etc.24 Eki 2019

Django has support for writing asynchronous (“async”) views, along with an entirely async-enabled request stack if you are running under ASGI. Async views will still work under WSGI, but with performance penalties, and without the ability to have efficient long-running requests.
