A Survey of the State-of-the-art in Event Processing

Applications that require real-time or near-real-time processing of high-volume of data streams are pushing the limits of traditional data processing infrastructures. These event-based applications include market feed processing and electronic trading on financial markets, network and infrastructure monitoring, cloud computing applications, fraud detection, and command and control in military environments. Furthermore, great changes were caused by cheap micro-sensor technology. This ubiquity of sensors in the real world can lead to a big field of novel monitoring and control applications with high-volume and low-latency processing requirements. This survey aims to review the state-of-the-art in event processing systems. A set of the most significant weaknesses and limitations is discussed at a high level, and we also outline requirements that a system should meet to excel at a variety of event processing applications.
