Geospatial event analytics leveraging reactive programming

In this paper, we present a solution to this year's DEBS Grand Challenge based on concepts from reactive systems. Reactive systems is a system architecture style with the following properties: Responsive, resilient, elastic, and message driven. When systems are built based on these properties, they tend to be more flexible, loosely-coupled, and scaleable. In this paper, we describe how to combine the operators given in the ReactiveX API to realize the individual challenge queries using asynchronous data-flows and evaluate the performance.
