I'm just coming back to web/API development Python after 7-8 years working on distributed systems in Go. I just built a Django+Celery MVP given what I knew from 2017 but I see a lot of "hate" towards Celery online these days. What issues have you run into with Celery? Has it gotten less reliable? harder to work with?

Celery + RabbitMQ is hard to beat in the Python ecosystem for scaling. But the vast, vast majority of projects don't need anywhere that kind of scale and instead just want basic features out of the box - unique tasks, rate limiting, asyncio, future scheduling that doesn't cause massive problems (they're scheduled in-memory on workers), etc. These things are incredibly annoying to implement over top of Celery.

Yeah that list right there. That's exactly it.

We don't hate Celery at all. It's just a bit harder to get it to do certain things and requires a bit more coding and understanding of celery than what we want to invest time and effort in.

Again, no hate towards Celery. It's not bad. We just want to see if there are better options out there.

For an even lighter system than Celery, I'm a big fan of

https://python-rq.org/

It's super low on the dependencies and integrates nicely as a library into python applications. It's very bare bones.

Most Django projects just need a basic way to execute timed and background tasks. Celery requires seperate containers or nodes, which complicates things unnecessarily. Django 6.0 luckily has tasks framework -- which is backported to earlier django versions has well, which can use the database. https://docs.djangoproject.com/en/6.0/topics/tasks/

Django 6's tasks framework is nice but so far it is only an API. It does not include an actual worker implementaiton. There is a django-tasks package which does a basic implementation but it is not prod ready. I tried it and it is very unreliable. Hopefully the community will come out with backends for it to plug celery, oban, rq etc.

I like celery but I started to try other things when I had projects doing work from languages in addition to python. Also I prefer the code work without having to think about queues as much as possible. In my case that was Argo workflows (not to be confused with Argo CD)
