Siddhi Distribution

Jenkins Build Status GitHub (pre-)release GitHub (Pre-)Release Date GitHub last commit License

Introduction

Siddhi is a Streaming and Complex Event Processing engine that listens to events from data streams, detects complex conditions described via a Streaming SQL language, and triggers actions. This repo contains necessary source code which creates the Siddhi runner and Siddhi tooling distributions by embedding Siddhi library in it.

Siddhi maintains two distributions as Siddhi-Runner and Siddhi-Tooling distribution.

  • Siddhi-Runner distribution bundles the Siddhi runtime which runs the Siddhi logic in a production environment.

  • Siddhi-Tooling distribution bundles the tooling editor profile which can be used for developing, testing and debugging Siddhi applications before moving to production.
