Topology configuration enables automatic server grouping and configuration change mirroring. It uses a master and slave architecture for mirroring shared data across the topology.
All writes and updates are forwarded to the master, 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.
Note:
To remove a server from the topology, you must uninstall it with the uninstall tool.
