A high performance engine for concurrent complex event processing

摘要

This paper describes the architecture, prototype implementation and performance analysis of a complexrnevent processing engine that can scale up to very large numbers of concurrent events while keeping thernrequirements on system resources predictable and low. The main innovation of this approach is that eachrninstantiated event pattern is handled by a dedicated Erlang process, instead of a single or shared operatingrnsystem thread. This in turn, reduces the latency in processing the event processing as it avoids the overheadsrnassociated with resource contention. We demonstrate how this approach can achieve linear event processingrntimes under high event loads, using modest computing resources.
