Not sure I would call that setup simple, but it is interesting. I have honestly never heard of ‘Raft’ or the Raft Consensus Protocol or bknr.datastore, so always happy to learn something on a Friday night.
I agree, the infrastructure required to make this happen eventually gets quite complicated. But the developer experience is what's super simple. If somebody had to take all our infrastructure and just use it to build their next big app, they can get the simplicity without worrying about the internal plumbing.
Raft is fantastic and most modern systems with more than one node are built on Raft. It is actually proven to be equivalent to Paxos, but the semantics of it are closer to what you would prefer as a software writer and the implementation is much simpler.
