Open edX是目前主流的三大慕课平台之一,它利用非关系型数据库MongoDB支持其大量教学数据的高速存储和高并发访问。该文重点分析了MongoDB内置的GridFS文件系统特点,提出调整存储关键参数等优化方法,搭建安全可靠的分布式数据存储,实现慕课教学资源存储的合理优化。
As one of the three most popular MOOC platforms,Open edX ensures high speed storage and high concurrent accessing of mass teaching data with the help of NoSQL database MongoDB.This paper analyses the advantages of GridFS on storage and accessing huge amounts of unstructured data,and researches into some key-value configurations for further improvement on data storage and high reliability accessing of MOOC.
