Django channels Sec WebSocket protocol

Python code runs at exactly the same speed whether it is written in sync or async style . Aside from the code, there are two factors that can influence the performance of a concurrent application: context-switching and scalability.

Since Django is a web framework built on top of Python, it’s not asynchronous either and that means there are issues like a view in a Django application getting stuck in a case where one or more operations take too much time to complete .

await is used to call asynchronous functions that perform I/O . async_to_sync is no longer needed when calling methods on the channel layer.

Channels is comprised of six packages:

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.

With the Django 3.1 release, Django now supports async views , so if you are running ASGI, writing async specific tasks is now possible! In this tutorial, we’ll build an example using the async view and compare it to a sync view using a mock HTTP request service.
