Minion Task Engine

Overview

The Task Engine is responsible for:

• Providing a REST based API
• Handling requests from trusted components (eg the Web UI)
• Scheduling work across the available resources (ie plugins)
• Persisting data

Main Classes

TaskEngine

This is the guts of the task engine, and will implement (or control) all of the functionality.

It can be run 'inline' for testing / development purposes.

TaskEngineRestApi

This is a wrapper around the TaskEngine, and provides a simple REST API.

At some point this will become a 'proper' stand alone service.

TaskEngineClient

This provides the same interface as the TaskEngine, but communicates with a separate task engine process via the REST API.

Clients should be able to switch between the TaskEngine and the TaskEngineClient without having to make any changes.

Notes

• It should persist all data to a db and maintain as little data in memory as possible.
  • This will allow us to run multiple Task Engine servers for one service, with all of the synchronization happening via the db (which would probably be clustered).
• To start with we'll probably implement the minimum necessary functionality to get the basics working
• In future phases there will be significant functionality to implement here :)
