Stream Insight Sample Clauses

Stream Insight. Microsoft’s StreamInsight [17] is a temporal main-memory query processing engine over complex event streams integrated in the .NET framework. Program modules can be defined that reads streams of events and iteratively processes the events to produce new (derived) streams of events. Each event has an associated life span (time interval) and the processing is often based on transforming and aggregating such time oriented events. A library of window forming primitives transform the streams into windows of events over which queries can be stated using the procedural query language LINQ [11]. The system is extensible by allowing the programmer to define own operators and aggregate functions in C#. No L-ratings are reported.
