摘要
NoSQL数据库以其支持数据高并发读写,海量数据高效率存储和访问,以及高扩展性和高可用行的特点在分布式存储系统中得到了广泛的应用。通过对分布式存储系统负载均衡的研究,提出了使用一致性哈希函数来实现系统负载均衡,并通过添加为集群节点添加虚拟节点的方式来增加缓存的命中率。
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.
