Frequently Asked Questions

How many nodes do you need in the control plane?

The cluster is healthy as long as the nodes in the control plane can reach a quorum to elect a new leader in case of failure. The quorum is (N-1)/2 where N is the initial number of nodes in the control plane. If the number of healthy nodes goes below this number, the cluster must recover before it resumes normal operations.

What happens if the control plane is unhealthy?

The data plane will continue to route the requests based on the latest known configuration.
