Replica nodes are read-only copies of a primary database that provide high availability, load balancing, and disaster recovery for Vultr Managed Databases.

Replica nodes are read-only copies of the primary node in a Vultr Managed Database. They maintain a near real-time copy of the database through asynchronous replication, which ensures that data written to the primary node is propagated to the replicas. Replica nodes can be used to distribute read traffic, reduce the load on the primary node, and improve overall performance for read-heavy workloads.
You can create replica nodes during the initial cluster provisioning or add them later by selecting Add Read-Only Replica Node in the Actions menu on your cluster's Overview page in the Vultr Customer Portal. Replica nodes are automatically synchronized with the primary node, and any changes to it are reflected on all replicas.
