【摘要】 为解决Storm编程模型无法处理具有迭代结构的应用程序的问题,从迭代结构程序的特点出发,在Storm编程模型的基础上通过增加Receiver、IBolt、Checker组件组建迭代Topology,设计了一种可以处理迭代结构的编程模型,分析了这种模型实现原理,对这种模型的新增组件和其对应的应用程序接口进行介绍和分析,同时,在Storm系统架构基础上设计了一种迭代Topology的实现方案,描述了这种实现方式下解决具有迭代结构程序的具体过程,最后使用这种模型模拟实现K-Means算法,实例论证这种迭代模型的可行性。更多还原

【Abstract】 To resolve the problem that Storm programming model can not dispose the application program of iterative structures, this paper started with the characteristics of the program of iterative structures, constructed the iterative Topology by adding components Receiver, IBolt and Checker based on the Storm programming model, designed a new programming model which can deal with the iterative structures,analyzed the principle of this model,introduced the new components and itsApplication Programming Interfaces in detail, and made a design on its implementation, described the process of iterative structures programming. Finally simulated the implemention of the K-Means algorithm by the model, which proves its feasibility.更多还原
