Elastic complex event processing
Thomas Heinze · 2011
Complex Event Processing (CEP) systems are designed to process large amount of information by simultaneously evaluating multiple queries over event streams. Two main requirements imposed by the users of the CEP systems are: (1) ability to process high throughput event data and (2) ability to answer queries with very low latency. In order to meet above requirements CEP systems are becoming increasingly distributed. Distribution of queries as well as event streams across multiple nodes facilitates increasing the throughput of CEP systems while simultaneously maintaining low response times.
