基于K-V模式的高可用性分布式存储技术研究

随着互联网的普及,用户量的日益增多,每天互联网上产生的数据高达T级别甚至P级别,因此对数据的存储提出了更高的要求。针对K-V模式的高可用分布式存储技术进行研究,重点分析Dynamo系统的高移植性、高可用性、高扩展性特点,并对Dynamo系统中涉及的分布式哈希算法、哈希树、Gossip协议进行阐述。

Research on High-Availability Distributed Storage Technology Based on K-V Mode

With the development of Intemet, computers become a common tool in daily life and more and more people enjoy surfing the Internet. With the increasing number of customers on Internet, companies have to deal with data in TB or even PB every day, resulting in higher requirement of database to cope with large scale data. This paper mainly focuses on the research on one of the distribute database, and distribute database will and must be applied widely in practice, due to its high availability, real-time, and great extensibility.
