MongoDB数据负载均衡的研究与优化
首发时间:2014-12-16
摘要:传统的关系型数据库已无法满足海量数据的存储与访问需求。针对这个问题,非关系型数据库(NOSQL)应运而生,本文主要研究了NOSQL家族中的优秀一员MongoDB。讨论了MongoDB的自动分片功能,研究了一致性哈希算法对于MongoDB负载均衡性能的改进。实际应用结果表明,该方法可以避免资源浪费及服务器过载。

Study and optimization of data load balancing in MongoDB
Abstract:The traditional relational database has been unable to meet the demand of massive data storage and access. Non relational database emerge as the times require, this paper mainly studies the MongoDB whitch is an outstanding member of Nosql family. Discusses the sharding in MongoDB , studies the consistent hashing to improve performance of data load balancing in MongoDB. The practical results show that, this algrithm can avoid the waste of resources and server overload.
Keywords: MongoDB load balancing consistent hashing
