摘要
在简要说明数据库复制技术目标的基础上,本文重点展开论述了数据库复制中的核心问题、解决方法与研究现状。通过对已有复制协议从不同侧面的分类,本文分析了各种协议不同的性能和可用性特点;通过对lazy和eager两种模式下复制协议的深入分析,揭示了技术发展的历史脉络和当前进展;对新兴应用需求进行归纳,得出了数据库复制技术可能的新发展方向。
This paper firstly introduces the objectives of database replication in brief, mainly focuses on discussing the key problems, solutions, and the present situation of research on database replication. Based on classifying the existing replication protocols from different angles, we analyze their respective performance and availability features; based on analyzing the replication protocols under lazy and eager modes, we discover their lineage and current evolution; based on summing up the burgeoning application requirements, we conclude the possible future research issues of database replication.
