»Enhanced Read Scalability with Read Replicas

Enterprise

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 servers and read replicas. Read replicas 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.

For more details, review the Consul server configuration documentation and the -read-replica configuration flag.
