Where event processing is going in 2020, and how it will make the world proactive?

Kolloquium Angewandte Informatik


While event processing is considered as an emerging technology in enterprise computing, it barely scratched the surface of its potential. This talk will describe our vision for the next generation of event processing in where it is used everywhere, consumed by everybody (enterprises as well as consumers) and used for reactive as well as proactive purposes. These topics reflect some of the areas in which the event processing activities within IBM Research deal with.

The presentation starts with the vision of event processing of the future and its associated research challenges and surveys three related research projects we are doing in IBM Haifa Research Lab.

Proactive applications: The processing of events enabled the shift from responsive mode (the system responds to the user's request) to reactive mode (the system reacts to detected events), proactive applications enable the next phase of this evolution: the computerized system predicts that it will get to undesired state, and should get automatic decision of how best to re-plan it actions before this undesired state actually happens. In the presentation the proactive notion with multiple examples and give an overview of our architecture and solution

Specifying applications correctness: Higher level languages and Graphical user interfaces make it easy to develop applications, however event processing adds the time dimension to application, where temporal properties of events and orders of execution can generate results that are not consistent with the users' intuition. Ensuring correctness as part of the application specification is a major challenge and can reduce the conceptual gap between non-technical users and the ability to develop event processing applications. In the presentation we illustrate some correctness issues and explain possible solutions.

Optimization of event processing networks: Survey of current work on optimizations of event processing networks including black-box and white-box optimizations. We'll describe in detail recent work that deals with optimization of complex event patterns using pattern rewriting techniques.
