随着物联网建设的不断发展,以实时传感数据为基础的各类流数据如何及时快速存储已成为当前急需解决的问题.面对连续不断到达的数据流,数据流存储系统必须及时快速将其存储到持久化介质中.针对这一需求,本文提出了一种基于缓存的分布式实时存储方法DRS.DRS方法依据窗口阈值,不间断地从缓存区接收数据,并结合一致性哈希算法将数据分布存储到数据服务器中.实验表明,该分布式存储方法能够实时地将数据存储到持久化介质中.

With the development of Internet of Things,the timely and fast storage of various types of streaming data based on real-time sensor data is becoming the urgent problem to the Internet of Things applications. Facing the arriving data stream continuous?ly, data stream storage system must store the results persistently in a timely way. In order to resolve the problem, we propose a new method, DRS(Distributed Real-Time Storage),which is based on cache. According to the threshold of the window ,DRS receive data from cache continuously and store data distributively in the data server with using the consistent hashing algorithm. Experiments show that DRTS can make the data store to the server in real time.
