I have a django project with various apps, which are completely independent. I’d like to make them run each one in their own process, as some of them spawn background threads to precalculate periodically some data and now they are competing for the CPU (the machine has loads of cores, but you know, the GIL and such…)
So, is there an easy way to split automatically the project into different ones, or at least to make each app live in its own process?
You can always have different settings files, but that would be like having multiple projects and even multiple endpoints. With some effort you could configure a reverse proxy to forward to the right Django server, based on the request’s path and so on, but I don’t think that’s what you want and it would be an ugly solution to your problem.
The solution to this is to move the heavy processing to a jobs queue. A lot of people and projects prefer Celery for this.
If that seems like overkill for some reason, you can always implement your own based on simple cron jobs. You can take a look at my small project that does this.
