High availability: High availability is achieved through multiple readable and writable backups; Final consistency: fast and complete data synchronization is achieved through hash tree (data may be inconsistent in a short time); Easy expansion: capacity expansion can be carried out without interrupting services; High performance: asynchronous IO and high performance Key Value data Tokyo Cabinet ； Configurable availability and consistency: configured through N, W, R; Simple protocol: Memcached Compatible protocol, a large number of available clients.
