Latest Released Version 4.0.0.

Welcome to the WSO2 Complex Event Processor.

WSO2 CEP is a lightweight, easy-to-use, open source Complex Event Processing server. It identifies the most meaningful events within the event cloud, analyzes their impact, and acts on them in real-time. It's built to be extremely high performing with WSO2 Siddhi and massively scalable using Apache Storm. CEP can be tightly integrated with WSO2 Data Analytics Server, by adding support for recording and post processing events with Map-Reduce via Apache Spark, and WSO2 Machine Learner for predictive analytics.
