| 摘 要： | 随着云计算时代的到来,大型Web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亟待解决的问题.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Cassandra的应用较为广泛.以分布式的多节点架...

| 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. |
