基于键值存储的事务控制策略

摘要

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 .%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。
