Scalable Distributed Inverted Index Built on Cassandra

As the age of cloud computing,giant Web-scale application and massive data exert big challenges on centra-lized 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.
