alt Hacker NewsThe "world" runs on Kubernetes which is using Raft: https://pkg.go.dev/go.etcd.io/etcd/raft/v3
Are you saying that this implementation is wrong?
"This Raft library is stable and feature complete. As of 2016, it is the most widely used Raft library in production, serving tens of thousands clusters each day. It powers distributed systems such as etcd, Kubernetes, Docker Swarm, Cloud Foundry Diego, CockroachDB, TiDB, Project Calico, Flannel, Hyperledger and more."
One of the most popular distributed DB is Cockroach which is written in go and also uses Raft: https://github.com/cockroachdb/cockroach/tree/master/pkg/raf...

Surely the King is doing it, so that must be the correct way. Look, the King even wears clothes and is totally not naked at all.
That the world runs on Kubernetes is no qualitative statement about the correctness of its Raft implementation. You can say that it's clearly good enough to not matter most of the time, but that is a different statement. No matter who you look at, they're just cooking with gas like you do, and they can make mistakes in just the same way.
Now; I'm only attacking your argument. I do neither know nor particularly care about the correctness of that implementation itself. There's been better refutations of the claim you replied to in other answers anyway.
etcd has had numerous liveness and safety bugs, with one happening as recently as December of 2025. Would you consider that a correct implementation?
