基于MongoDB的元数据管理研究

Research on metadata management based on MongoDB

在研究了众多NoSQL数据库以及元数据管理策略的基础上,文中实现了一套基于MongoDB的元数据管理方案。该方案利用MongoDB的高性能以及可扩展性,很好地解决了元数据服务的可扩展性问题以及性能瓶颈问题。并且,在元数据结构的设计上,每条元数据只依赖其父目录的ID,避免了目录属性的修改对其他元数据的影响。同时,利用MongoDB高效的索引机制提高了查询效率。实验表明,根据该方案实现的元数据管理系统具有较高的性能以及稳定性。

Based on the study of many NoSQL databases and metadata management strategies,this paper implements a set of metadata management scheme based on MongoDB. The program leverages MongoDB＇s high performance and scalability to solve the problem of the scalability issues and performance bottlenecks of metadata services. And in the design of the metadata structure,each metadata depends only on the ID of its parent directory,avoiding the effect of directory attribute modification on other metadata. At the same time,using MongoDB ＇s efficient indexing mechanism improves the query efficiency. The experiments show that the metadata management system is implemented according to the scheme,it has high performance and stability.
