The power of Tungsten Clustering for MySQL / MariaDB is its built-in intelligent MySQL proxy, known as the Tungsten Connector. The Connector has built-in read-write splitting capabilities, and it is also possible to configure different algorithms which select the appropriate slave (i.e. Round-Robin or Lowest-Latency).
