# Topology configuration

Topology configuration enables grouping servers and mirroring configuration changes automatically.

Topology configuration uses a primary/secondary architecture for mirroring shared data across the topology. All writes and updates are forwarded to the primary, which forwards them to all other servers. Reads can be served by any server in the group.
