摘要
在功能强大且分布性强的系统中,由于网络的延迟和中断可能导致属性更新被长时间的延迟,从而影响了系统工作的效率,重点属性在基于日志更新解决属性更新的技术中起到很大的作用.针对重点属性更新的特点,通过一个在线观看电影实例说明重点属性在属性更新中的应用及其如何进一步提高系统工作效率的.
The attributes update will be delayed for a long time by the network delay and network interruption in distribution system,thus affecting the work efficiency of the system.Key attributes play an important role in the attribute update technology based on logs update.In view of the characteristics of key attributes update,we tried to improve the key attributes updating optimization.We will illustrate the application of key attributes in attributes update with an on-line movie watching system,so as to further improve the system efficiency.
