Traefik conf for server-side events

ANSWER

Answered 2022-Mar-21 at 15:17

It turns out that Django's view that responded with the sse was setting 2 identical headers and that makes Traefik bristle.

Complete explanation on the issue.

Once fixed the headers everything worked.

QUESTION

Uvicorn async workers are still working synchronously

Asked 2022-Feb-07 at 18:39

Question in short

I have migrated my project from Django 2.2 to Django 3.2, and now I want to start using the possibility for asynchronous views. I have created an async view, setup asgi configuration, and run gunicorn with a Uvicorn worker. When swarming this server with 10 users concurrently, they are served synchronously. What do I need to configure in order to serve 10 concurrent users an async view?

Question in detail

This is what I did so far in my local environment:

I am working with Django 3.2.10 and Python 3.9.
I have installed gunicorn and uvicorn through pip
I have created an asgi.py file with the following contents

When running the gunicorn command, you can try to add workers parameter with using options -w or --workers.

It defaults to 1 as stated in the gunicorn documentation. You may want to try to increase that value.

So figured out what was wrong. I am using docker-compose and on creating the containers, I never shared the DB variables in the environment of the daphne server. As I was focused on the websockets it never arose until I tried to access the db via the Django model. Anyways all is good now but I'll leave this here in case someone was as silly as I was!

When running, I can see that Poetry is installed correctly, and that Poetry installs the packages in my pyproject.toml, including Django.
