Using Siddhi CEP as a Java library


WSO2 Complex Event processor uses Siddhi as the Backend Runtime Engine, which was initially developed at http://siddhi.sourceforge.net/, and its development is now being continued as a commons project of WSO2 Inc.
Siddhi under Apache License V2, and its a product designed for real time processing both in standalone mode and in distributed mode.

Siddhi is basically a Java library that's embedded in WSO2 CEP server to provide enterprise integration for Complex Event Processing.

Since Siddhi is just a java library here are some samples demonstrating siddhi’s capabilities as a library.

You can find the WSO2 CEP product from: 

You can find the Documentation for WSO2 CEP from: 

You can find the Documentation for Siddhi Language Specification from:

  2. Yes, you can add that using the following Maven dependency configuration

    <dependency>
    <groupId>org.wso2.siddhi</groupId>
    <artifactId>siddhi-api</artifactId>
    <version>2.0.0-wso2v1</version>
    </dependency>
    <dependency>
    <groupId>org.wso2.siddhi</groupId>
    <artifactId>siddhi-core</artifactId>
    <version>2.0.0-wso2v1</version>
    </dependency>
    <dependency>
    <groupId>org.wso2.siddhi</groupId>
    <artifactId>siddhi-query</artifactId>
    <version>2.0.0-wso2v1</version>
    </dependency>

    and by adding the following WSO2 public Maven2 repository

    <repositories>
    <repository>
    <id>wso2-maven2-repository</id>
    <name>WSO2 Maven2 Repository</name>
    <url>http://dist.wso2.org/maven2</url>
    </repository>
    </repositories>

  3. This information should be made available in the WSO2 CEP user guide.

  4. Hi,

    Don't suppose you know where I can get the source code for 2.0.0-wso2v4? Using it within a java project and trying to debug it is a nightmare without it! Thanks
