针对区域图书馆数字特色资源的分布式云存储研究

Research on Cloud Storage of Digital Feature Library Resource Based on HDFS

在图书馆数字特色资源向大数据发展的趋势下,探讨更科学有效的存储管理系统,从而提升图书馆特色数字资源服务质量。应用基于HDFS的云存储技术,设计一套针对海量的图书馆数字特色资源的云存储框架,通过对HDFS涉及的技术细节,包括元数据存储策略,数据存储策略以及数据容错机制展开具体分析。用户不需要考虑HDFS背后运作的技术细节,只需要熟悉用户界面的相关操作,理论上具有良好的用户体验度,该模型已经在技术上实现并应用于贵州省内的图书馆数字特色资源公共服务平台,效果还有待进一步研究探讨。

In the trend of developing from digital library resource to the big data, this paper explored more scientific and effective storage management system, so as to promote the service quality of digital library resource. It applied the cloud storage technology based on HDFS to design a set of cloud storage framework for massive digital library resource,and made the deep analysis on the related technology detail of HDFS, including metadata storage strategy, data storage strategy and data fault-tolerant mechanism. Users need to be familiar with the operation of user interface without the consideration of technical detail of the HDFS behind, which in theory showed a good user experience degrees. It has realized in the technical implementation and been applied in the digital library resource public service platform in Guizhou, and its effect still needs further research.
