Description
Summary:V elocity is one of the 4 Vs commonly used to characterize Big Data [5]. In this regard, Forrester remarked the following in Q3 2014 [8]: "The high velocity, white-water flow of data from innumerable real-time data sources such as market data, Internet of Things, mobile, sensors, click-stream, and even transactions remain largely unnavigated by most firms. The opportunity to leverage streaming analytics has never been greater." Example use cases of streaming analytics include, but not limited to: (a) visualization of business metrics in real-time (b) facilitating highly personalized experiences (c) expediting response during emergencies. Streaming analytics is extensively used in a wide variety of domains such as healthcare, e-commerce, financial services, telecommunications, energy and utilities, manufacturing, government and transportation. In this tutorial, we shall present an in-depth overview of streaming analytics -- applications, algorithms and platforms -- landscape. We shall walk through how the field has evolved over the last decade and then discuss the current challenges -- the impact of the other three V s, viz., V olume, V ariety and V eracity, on Big Data streaming analytics. The tutorial is intended for both researchers and practitioners in the industry. We shall also present state-of-the-affairs of streaming analytics at Twitter.
