Persistent in-memory Python object for nginx/uwsgi server

Question

I doubt this is even possible, but here is the problem and proposed solution (the feasibility of the proposed solution is the object of this question):

You said nothing about writing this data back, is it static? In this case, the solution is every simple, and I have no clue what is up with all the "it's not feasible" responses.

Uwsgi workers are always-running applications. So data absolutely gets persisted between requests. All you need to do is store stuff in a global variable, that is it. And remember it's per-worker, and workers do restart from time to time, so you need proper loading/invalidation strategies.

If the data is updated very rarely (rarely enough to restart the server when it does), you can save even more. Just create the objects during app construction. This way, they will be created exactly once, and then all the workers will fork off the master, and reuse the same data. Of course, it's copy-on-write, so if you update it, you will lose the memory benefits (same thing will happen if python decides to compact its memory during a gc run, so it's not super predictable).
