基于MR的高可靠分布式数据流统计模型
Statistical Model of Distrubuted Data Strem with High Reliability Based on MR
摘要
Abstract
According to the unique characteristics of the data stream,with consecutive grouping statistics based on window model in the data flow as application scenarios,combined with the advantages of mainstream stream data processing platform like Storm and Spark Streaming, we propose a distributed statistical model of data stream with high throughput and scalability as well as low latency,namely Mars. It solves the problems of strong throughput and low latency due to losing data easily and strong timelessness. On the fault-tolerant,Mars provides at-least-once semantic support against major errors. It is tested in real experiment environment and made a comparison with the currently pop-ular distributed flow processing platform Spark Streaming and Storm,which show that it is between them in real-time operation delay for da-ta. However,in terms of the scale of the cluster,Mars' throughput rate is significantly better than that of the two,and in terms of semantic accuracy,it achieves the semantic limits of the same level as Storm.关键词
