Abstract: Database cluster is an effective architecture,which can increase database throughput and decrease transaction response time.In this paper,we research and implement a type of common share-nothing database cluster,which includes a lot of heterogeneous dtabase node.Cluster support horizontal partition and replication.TPC-C test prove that this architecture has high price performance ratio and extensibility.

摘要： 数据库集群是提高数据库系统事务吞吐率,降低响应时间的有效机制。研究并实现了一种通用的无共享的数据库集群,集群由异构的节点数据库组成。系统支持水平数据划分和数据复制,系统具有性价比高,可扩展性好等特点。
