摘要 该文提出了一种改进的分布式数据存储策略。该文的改进策略基于一致性哈希数据分布算法,采用虚拟节点的方式进行数据的分布式存储,并实时监控各存储节点的负载率进行均衡调整。该策略采用标注优先级的方式快速提升新增存储节点的利用率,有效地优化了整个存储系统的性能,提高了负载均衡的整体效果。 This paper presents an improved distributed data storage strategy.In this paper,the improved method based on the consistency hash data distribution algorithm,the use of virtual nodes in the way of distributed data storage,and real-time monitoring of the load rate of each storage node to adjust the load rate.In this method,the utilization of the new storage nodes is rapidly improved by means of the method of priority,and the performance of the whole storage system is optimized,and the whole effect of load balancing is improved.
