The DEBS 2014 grand challenge

Event processing systems in general and data stream processing systems in particular focus on processing of queries over unbounded event streams. The goal of the DEBS 2014 Grand Challenge is to provide a specific problem, originating from the domain of energy data management, which can be leveraged by both commercial and academic event processing systems. The problem provided by this year's challenge seeks to highlight the capability of event stream processing systems towards combining of the processing of live and historical event data as well as scaling out for coping with high velocity data streams and complex analysis.
