摘要
近年来,分布式文件系统在海量数据存储领域得到了广泛的应用。当前主流的分布式文件系统大都采用文件数据与元数据解耦的分布式架构,元数据的管理机制直接影响着文件系统的整体性能,该文主要研究了分布式文件系统中元数据管理的不同机制,并对它们之间的优缺点进行了详细的对比,最后探讨了元数据管理所面临的问题和今后的发展趋势。
In recent years,distributed file system in the mass data storage areas has been widely used.he current mainstream of the distribut ed file system mostly adopts the file data and metadata decoupled distributed architecture,metadata management mechanism directly affects the overall file system performance,this paper mainly studies the different mechanisms adopted by distributed file system,and presents a de tailed analysis of the advantages and disadvantages of them,finally discusses the metadata management problems and future development trends.
