A High Performance Engine for Concurrent CEP in Erlang

  • Bill Karakostas
Part of the Studies in Computational Intelligence book series (SCI, volume 446)


This paper describes the architecture, prototype implementation and performance analysis of a complex event processing engine that can meet soft real time constraints, and scale up to many thousands of concurrent events. We have avoided the resource overheads associated with the processing of large numbers of concurrent events (such as, for example, those generated by user sessions in a web site) by using lightweight Erlang processes and a ‘shared nothing’ architecture. We demonstrate how this approach can achieve predictable event processing times under varying loads, using only modest hardware resources in an SMP architecture.
