面向海量数据的分布式用户态文件系统研究与设计

云计算、物联网、互联网技术的迅猛发展,使社会进入了大数据时代。随着数据量的指数增长,面对海量数据的高效存储与访问成为目前人们面临的主要问题。使用分布式存储作为底层数据存储系统,基于用户空间文件系统fuse,结合MongoDB数据库管理元数据,研究设计出一种面向分布式存储的用户态文件系统。相对于传统分布式对象存储系统的数据访问,设计的文件系统具有很高的灵活性和可扩展性,同时对于用户有着可操作性强、易于管理等优点,使其更适用于现代海量数据的访问与管理。

Research and Design of Massive Data-oriented Distributed User-state File System

The rapid development of cloud computing,IoT(Internet of Things),and Internettechnologies has brought society into the era of big data.With the exponential growth of data volume,efficient storage and access to massive data has become a major problem that demands prompt solution.Byusing distributed storage as the blue ocean storage system,based on the user space file system fuse,and combined with MongoDB database to manage metadata,a user-state file system for distributed storage is explored and designed.Compared to the traditional distributed object storage system for data access,the designed bfs-fuse system has high flexibility and scalability,and possesses the advantages of strong operability and easy management for users,thereby making it more suitable for the access and management of modern massive data.
