摘要
介绍基于键值存储的优点以及发展趋势,提出键值存储模型中支持事务的方法。新型的键值存储数据库应该具备传统数据库的事务能力,新型数据库实现事务控制,需要与传统关系型数据库不同的策略,本文描述使用写前日志WAL(Write-ahead Log)和并发版本系统CVS(Concurrent Versions System)的事务控制,满足ACID特性。
This article describes the advantages and development trends based on key-value storage. It also proposes ways to support transactions in the key-value storage model. New key-value storage database should have the ability of traditional database transac- tion and the new database transaction control requires a different strategy from traditional relational database. This paper describes the use of write-ahead log (WAL) and concurrent versions system (CVS) transaction control to meet the ACID properties.
