About evQueue

evQueue is an open source job scheduler and queueing engine. It features an event-driven C++ engine and a ReactJS control interface (available as a browser plugin), which provides tasks monitoring and creation.

It provides both simple task execution and complex task chaining (workflow) using an easy to use drag & drop web interface. Workflow description includes output linking to input, conditions, loops... Queues management provides an easy way for task parallelization and resource control.

The network API provides an easy way, XML based, for synchronous or asynchronous workflow launching and control, allowing tasks to be launched from external applications or web pages. You can thus execute heavy tasks on a remote (dedicated) machine to save resources on your web frontends while providing live reporing of the treatment to you users.

evQueue is agentless (remote connection is made through SSH) and works on Linux environments. We provide debian packages. For other distributions you can compile from source or use our Docker images.

We now support clustering and high availability using any number of synchronized nodes. Schedules (like cron) can be launched on an elected node to guarantee high availability.

Workflows and tasks can be synchronized to a git repository to allow instant production deployment and history.

New version is shipped with a Websockets server, allowing fully event based frontend integration (default frontend is using ReactJS).
