    It's curious that the project they based their server on ( ) supported class C long before Helum decided to be a LoraWAN provider. So, they actually throw out the code they were unable to adopt to their so-called "archictecture", and I'm not sure that they were thinking about (if they were thinking at all) at that moment.

    Disk works too, but if you're multi-node this means you now have a distributed database embedded in your system, which may or may not be your goal :)

    RabbitMQ does this, they developed a library for "persistent, fault-tolerant and replicated state machines" based on Raft:
