# Topology configuration

Topology configuration enables automatic server grouping and configuration change mirroring. It uses a primary and 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, and servers can be added to an existing topology at installation.
