Look at the Raft protocol. In general you’d rather not integrate at the protocol layer; it’s standard to use a consistent store like etcd that implements Raft for the coordination/data that needs to be serializable. (Kubernetes uses etcd so it scales pretty well for a strongly-consistent k/v store.) You said “multiple datastores” so I’m assuming you have heterogenous data and something like CockroachDB isn’t an option. > I'm a beginner in this topic and I find this topic interesting. Not trying to gatekeepe but rolling your own is dangerous. See https://aphyr.com/ https://aphyr.com/ for the gold standard in testing (great educational material). You can use Jepsen to test your distributed systems. But better to just use datastores that Kyle has shown are solid.
