摘要
CDN对于动态Web应用的加速通常采用数据缓存或复制技术。针对论坛、博客服务提供商等为注册用户提供个人信息发布平台的网站,提出了一种基于用户的数据分割方法:将数据按所属注册用户进行分割,分布到离该用户最近的数据库系统中。将数据库UID操作分散到多个数据库系统,消除了单个数据库系统的I/O瓶颈。
Content Delivery Network (CDN) adopts data replication or data caching methods to accelerate dynamic Web applications. A user-based data partition method especially for Websites that provide personal information publishing was proposed, such as forum, Web log service providers: partitions data into many parts according to users it belongs to, distributes to database systems near users. This method achieves better scalability because the write database queries are assigned to different databases.
