| 摘 要： | 最终一致性作为衡量NoSQL数据库性能的重要指标，对NoSQL的应用与发展起着重要作用。针对最终一致性解决方案存在的问题，提出基于向量时钟的最终一致性模型。模型为数据加入了版本的概念，通过版本向量和时间戳的引入，为数据标识了版本信息，同时给出了冲突检测和处理方案。对比分析表明，方案很好地解决了问题，提高了最终一致性的性能，在NOSQL数据库的设计过程中具有较好的应用价值。

| Abstract: | Eventual consistency is an important indicator when measuring the performance of NoSQL database, it has a signifi- cant influence in the development of NoSQL. In order to solve the problems of eventual consistency, this paper proposes a model based on vector clocks. The model adds a version to data. By importing vector and timestamp, it can mark data with the version. Furthermore, a solution of solving conflicts is presented. By comparative analysis, the solution improves the performance of eventual consistency and has a good application value in the design process of NoSQL database. |
