Evidently you don’t understand what people mean when they talk about stateless backend, so let me explain. The point there is regarding horizontal scaling. If your backend code is stateful then it has user context in memory, and requests for a particular user session have to be handled by the same instance of the service. With a stateless backend all the context lives on the client, and the requests can be handled by any instance on the backend. So now you can spin up as many instances of the service as you need, and you don’t need to care which one picks up the request. The fact that you might be persisting some data to the db in the process of handling the request is neither here nor there. Hope that helps you.
