LifeStream:一个高性能的周期流处理引擎

LifeStream: A High-Performance Stream Processing Engine for Periodic Streams

Anand Jayarajan, Kimberly Hau, Andrew Goodwin, Gennady Pekhimenko

摘要:

世界各地的医院每天都从患者那里收集大量的生理数据。最近,人们对这些数据进行统计分析以获得更多见解并提供更好的医疗诊断的研究兴趣有所增加。这种分析需要对大量数据进行复杂的计算,需要高效的数据处理系统。本文表明,目前可用的数据处理解决方案,要么无法满足性能要求,或缺乏简单,灵活的编程接口。为了解决这个问题,我们提出了\emph{LifeStream},一个高性能的生理数据流处理引擎。LifeStream通过提供丰富的时间查询语言支持实现了编程的轻松性,通过采用利用生理数据周期性的优化实现了性能。我们证明,LifeStream实现了端到端性能高达$7.5\times$高于国家的最先进的流引擎和$3.2\times$比手工优化的数值库在现实世界的数据集和工作负载。

英文摘要:

Hospitals around the world collect massive amounts of physiological data from their patients every day. Recently, there has been an increase in research interest to subject this data to statistical analysis to gain more insights and provide improved medical diagnoses. Such analyses require complex computations on large volumes of data, demanding efficient data processing systems. This paper shows that currently available data processing solutions either fail to meet the performance requirements or lack simple and flexible programming interfaces. To address this problem, we propose \emph{LifeStream}, a high-performance stream processing engine for physiological data. LifeStream hits the sweet spot between ease of programming by providing a rich temporal query language support and performance by employing optimizations that exploit the periodic nature of physiological data. We demonstrate that LifeStream achieves end-to-end performance up to $7.5\times$ higher than state-of-the-art streaming engines and $3.2\times$ than hand-optimized numerical libraries on real-world datasets and workloads.
