The Realization of Load Balancing in NoSQL

NoSQL database with its supporting data concurrent read and write,the high efficiency of mass data storage and access,as well as high scalability and high availability line features in a distributed storage system in a wide range of applications.Through the study of load balancing for distributed storage systems,the consistency of the hash function to the system load balancing,and by adding a way to add a vir tual node for the cluster nodes to increase the cache hit rate.
