This is really interesting. I wonder if etcd can benefit from this as it uses Raft for consensus and split-brain can be a problem depending on how its setup (usually when a Kubernetes control plane is initialized).

Yeah, for real. etcd is one of the biggest limitations to Kubernetes in my opinion. I would love to have a region-agnostic Kubernetes cluster.

I think all big cloud providers replaced etcd with a custom in house implementation in their K8s offerings for this reason

This is incorrect.

AWS, Azure, GCP still use etcd in their customer kubernetes services.

"EKS Ultra Scale" uses an in-house Journal

GKE uses spanner (with an etcd API layer) per the docs.
