During GSoC 2017, I worked on developing a Python Wrapper on Siddhi Complex Event Processor (Siddhi CEP) Java Library [GitHub, Release 3.1, Release 4.0, Wiki] developed by WSO2 Inc. The Python wrapper covered both versions 3.1.x and 4.x of Siddhi CEP by its two versions PySiddhi3 and PySiddhi4. Additionally, a REST API was developed for WSO2 Data Analytics Server (WSO2 DAS) 4.x as a feature of PySiddhi4.
