What business areas/problems is Esper best suited for?
Esper is best suited for real-time event driven applications. Typical application areas are business process management and automation, finance, network and application monitoring and sensor network applications. Esper take much of the complexity out of developing applications that detect patterns among events, filter events, aggregate time or length windows of events, join event streams, trigger based on absence of events etc. A primary difference with system relying on classical SQL databases is that we do not query a repository for events matching some conditions, but instead trigger customized actions as the flow of events come in matching event conditions – hence drastically reducing the latency.
