Yago

An asynchronous task runner built to be easy to use, safe and scalable. Powered by Node.js and TypeScript.

How it works

TaskRunner

It's a class that knows how to run a Task. Every new TaskRunner is registered using a new unique name and it's used to match which Tasks the runner can handle.

Task

A task is an instruction of something that has to be done at some time. Each task carries within the following information:

• An unique id
• A common name
• The expected date/time to start
• Payload: Additional information that can be used by the TaskRunner Every new task is first queued and will be processed when it's start date is reached. New tasks can be scheduled by:
• A cron settings
• Manually through the UI
• REST API
• yago-client (Node, Java, .Net, Python, etc.)

Queue

The queue holds a list of Tasks that are waiting to be processed. By default Yago supports two queue Implementation: InProcess and Redis.

• InProcessQueue: Useful when there's only one Yago instance and it's okay to lose the queue in case of a service outage.
• RedisQueue: The safer and best option for a bigger Yago implementation. Can handle cluster scenarios.
