| 摘 要： | 在分析分布式ETL中负载均衡重要性的基础上,针对传统ETL应用于分布式数据仓库中效率低的缺陷,提出一种根据ETL节点所抽取的数据类型不同对分布式ETL节点抽取的数据进行分割的策略,以及一种新的负载均衡模型—链网模型和Routers相结合的R-CN模型。在此基础上提出一种基于ETL数据分片和R-CN模型相结合的分布式ETL节点负载调度和均衡策略。此策略使ETL节点的数据处理能力有了很大的提高,有效地提高了分布式ETL的效率。

| Abstract: | After analyzing the importance of load balancing in distributed ETL,aiming at the limitation of traditional ETL used in distributed data warehouse,a new strategy that the data extracted from ETL node are divided according to the type of data is proposed,and then presents a new model of load balancing R-CN model that is combined by chain network model and Routers.On the basis of that presents a new load balancing strategy based on the data segment strategy and R-CN model.The strategy improves the ability of ... |
