- [KEP4444, Traffic Distribution for Services][kep4444]
- In alpha since Kubernetes 1.30, beta since Kubernetes 1.31
- Supersedes topology aware routing
- Should eventually supersede topology aware routing
- Multiple values are supported
- Can be set to `PreferClose` (more values might be supported later)
- `PreferClose` (alpha since K8S 1.30, beta since K8S 1.31, stable since K8S 1.33)
- The meaning of `PreferClose` is implementation dependent
"try to route traffic to endpoints in the same zone as the client"
(with kube-proxy, it should work like topology aware routing: stay in a zone)
- `PreferSameZone` (beta since K8S 1.34)
"same as `PreferClose` but clearer about the intended semantics"
- `PreferSameNode` (beta since K8S 1.34)
"try to route traffic to endpoints on the same node as the client"
