Latest Released Version 4.2.0.

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.

##Features

####Process data in motion, and analyze in real time.

• Powerful, extensible language for stream processing, powered by WSO2 Siddhi.
• SQL like query language providing intuitive and complex event processing support.
• Supports filtering by conditions, the ability to create and join event streams, execute temporal queries using various windows, event tables and partitions, and identifies sequences of event occurrences.
• Visualize, monitor and act in real time

####Template based, configuration driven execution plan design

• Event tracing, try-it, event flow visualization and event simulation capabilities
• Built-in collection and monitoring of standard access and performance statistics
• Effective real time dashboard with support for gadget generation
• Connect and integrate with anything.

####Support for many transport receivers, including for the Internet of Things (IoT)

• Data publisher agents to plug into enterprise systems
• Easily extend for scalability and high availability

####Extensible use case driven toolbox support including fraud detection, time series, geo fencing and natural language processing plugin.

• Supports high availability deployment.
• Supports distributed event processing with Apache Storm and Siddhi.
• Supports long running queries via persistence support
