数字图书馆大数据分布式存储架构模式与策略研究

Study on the Big Data Distributed Storage Architecture Model and Policies of the Digital Library

数字图书馆传统的关系数据库数据存储方式已不能满足大数据存储与处理需求,为解决传统关系型数据库在海量数据存储和访问效率中的瓶颈问题,论文提出了一种数字图书馆安全、有效的大数据公布式存储架构。该存储架构具有良好的可扩展性、容错性和存储性能,尤其针对海量的非结构化、半结构化数据,其性能优势更加明显。

Storing and processing big data by using ordinary relational database comes across some problems in the digital library. To solve the bottleneck problems of the traditional relationship database in big data storage and access efficiency, this paper presents a secure and efficient big data distributed storage architecture for the digital library, which has better scalability, fault tolerance and enhanced storage performance. Especially for the mass unstructured and semi-structured data, the performance advantage is more obvious.
