Supporting a spectrum of out-of-order event processing technologies: from aggressive to conservative methodologies

This demonstration presents a complex event processing system which focuses on out-of-order handling. State-of-the-art event stream processing technology experiences significant challenges when faced with out-of-order data arrival including huge system latencies, missing results, and incorrect result generation. We propose two out-of-order handling techniques, conservative and aggressive strategies. We will show the efficiency of our techniques and how they can satisfy various QoS requirements of different applications.
