»Enhanced Read Scalability with Non-Voting Servers
This feature requires Consul Enterprise with the Global Visibility, Routing, and Scale module.
Consul Enterprise provides the ability to scale clustered Consul servers to include voting and non-voting servers. Non-voting servers still receive data from the cluster replication, however, they do not take part in quorum election operations. Expanding your Consul cluster in this way can scale reads without impacting write latency.
