21 世纪以来,伴随着互联网和通信技术的不断发展以及电子商务实践的不断深入,电子商务平台正在展现出前所未有广阔的前景.同时,网络购物快速发展的同时也出现了一些亟待解决的实际难题,用户的增多,商品的繁多,电商平台模式已经进入了大数据时代,及时再强大的单个数据库也无法支持,解决方式就是分布式数据库[1],近几年分布式成为热门的话题,也成为大型Web应用系统必备良药,而在数据库方面应用更加广泛.通过采用普通廉价的设备构建出高可用性和高扩展的集群目的.从而摆脱了大型设备的依赖,一个好的分布式数据库架构可以比较方便达到高可用性有可以达到向外扩展的能力.但是分布式存储就必须面临分布式事务,本文提出一种方法能够避免分布式事务带来的效率问题.%since twenty-first Century,along with the continuous development of Internet and communication technology and the continuous development of e-commerce,e-commerce platform is showing unprecedented broad prospects.At the same time,with the rapid development of online shopping,there are some problems to be solved.With the increasing of the number of users and a wide variety of goods,business platform model has entered the era of big data.Timely and powerful single database can not support.The solution is a distributed database.Distribution in recent years has not only become a hot topic,but also become a large Web application system.And the application is more extensive in the database.High availability and high expansion of the cluster are constructed by the use of common in-expensive devices.In order to get rid of the dependence of the large-scale equipment,a good distributed database structure can be more convenient to achieve high availability and it has the ability to reach out to expand.But distributed storage must be faced with distributed transactions.The paper proposes a method to avoid the efficiency of distributed transactions.
