appengine-queue

h2. Overview

This demonstrates a simple Queue mechanism you can use in App Engine applications. It is based on code taken from "Jaikuengine":code.google.com/p/jaikuengine/ and then modified for a more generic purpose. Creating tasks is as simple as:

Where test is the name of the mapping in api.py, 1 is a unique identifier for the task and ['test argument 1'] is a list of arguments to pass to the test method.

Once you have a set of tasks in the queue you process them like so:

h2. Example

The main.py and api.py files contains a reference implementation. If you run the application you can visit "localhost:8080/seed":http://localhost:8080/seed to create a series of tasks and then "localhost:8080":http://localhost:8080/ to process a task at a time. In a real application you could set up an external cron to ping an end point to process items from the queue.

h2. Todo

• Jaikuengine has a test suite, some of which can be reused here. But I need to write a few test of my own to be sure everything is working.
• The whole codebase is in need of good comments to explain what's going on.
• Some variables have meaningless one or two letter names. This is a left over from the Jaikuengine code and just needs a bit of refactoring.
