JEPC: The Java Event Processing Connectivity

Abstract

Today, event processing (EP) is the first choice technology for analyzing massive event streams in a timely manner. EP allows to detect user-defined situations of interest, like in streaming position events for example, in near real-time such that actions can be taken immediately. Unfortunately, each specific EP system has its very own API and query language because there are no standards. The exchange of EP systems as well as their use within a federation is challenging, error-prone, and expensive. To overcome these problems, we introduce the Java Event Processing Connectivity (JEPC) that is a middleware for uniform EP functionality in Java. JEPC provides always the same API and query language for EP completely independent of the EP system beneath. Furthermore, we show in detail how JEPC can integrate database systems besides EP systems and evaluate the performance of EP powered by databases systems.
