摘　　要：提出一种基于主动TCP连接复制的高性能高可用MySQL数据库集群解决方案.该方案采用集群技术对并发的多个TCP连接进行原子多播转换和复制以达到连接容错的效果,同时,对连接流中的只读操作进行分流以达到提高性能的目的.该方案将对TCP连接进行复制的技术应用于MySQL数据库集群中,从而实现了数据库集群整体的高可用性和高性能.经过原型系统的实现和测试,证明了该方案在复制过程中对数据库写操作造成了较小的性能损耗,同时极大地提高了数据库集群的只读查询性能.In this paper, a scheme is presented, which builds high performance and high availability database cluster by using actively replicated TCP connections. The scheme forwards a technique that actively replicates a set of TCP connections by converting them into atomic multicasting and distributing read-only requests to different processing units. The technique is further used on MySQL database clusters and results in high performance and high availability. With the experiments conducted on the prototype systems, high performance on read-only database queries with little sacrifice on the update operations of the cluster is exhibited.
