摘要/Abstract

摘要： 随着云计算时代的到来，大型W cb应用的不断发展，海量数据不断增加，集中式的数据检索已不再满足需求。如何在分布式的环境中高效地处理数据检索成为亚待解决的问题。传统的关系型数据存储也无法完全适应云环境，NoSQL(Not only SQL)作为一种云存储形式应运而生，其中assandra的应用较为广泛。以分布式的多节点架构的索引构建为背景，提出了建立在分布可扩展的数据存储Cassandra之上的分布式反向索引(DII, Distributed Invcrtcd Index)，并给出了数据模型和查询处理流程的分析，最后给出了Cassandra的性能测试。

关键词: 云存储，分布式索引，反向索引，Cassandra

Abstract: As the age of cloud computing,giant Web-scale application and massive data exert big challenges on centralined data retrieval. It becomes a tricky issue to process efficiently data retrieval in distributed environment. Traditional relational database is not fully suitable to the cloud any more. As a novel cloud storage, NoSQL (Not only SQL) emerges, among which Cassandra is widely used. With the application of index building under the distributed multi-node architecture, a scalable distributed inverted index built on Cassandra was put forward to solve the problem. Besides, analysis on data model and processing flow, as well as a performance test about Cassandra, were proposed.
