A simple DB based queue, designed for situations where a server based queue is unnecessary.

This plugin requires Rails 2.* currently, and has only been tested on MySQL.

On rails 2.1 you can install straight from github:

ruby script/plugin install git://github.com/matthewrudy/rudeq.git

Else just check it out into your plugins directory:

git clone git://github.com/matthewrudy/rudeq.git vendor/plugins/rudeq

After you've installed it just run

rake queue:setup

matthew@iRudy:~/code/jbequeueing $ rake queue:setup
(in /Users/matthew/code/jbequeueing)
    exists  app/models/
    exists  spec/fixtures/
    exists  spec/models/
    create  app/models/rude_queue.rb
    create  spec/fixtures/rude_queues.yml
    create  spec/models/rude_queue_spec.rb
    exists  db/migrate
    create  db/migrate/029_create_rude_queues.rb

and you're done. Fully tested, fully indexed... BOOM!

Now run migrations, start up a console, and;

RudeQueue.set(:queue_name, RandomObject)
RudeQueue.get(:queue_name)
RudeQueue.fetch(:queue_name) do |data|
  process(data)
end

And, to keep the queue running fast, set up a cron job to run

rake queue:cleanup

the cleanup will remove any queued items which have been processed longer than an hour ago.

rake queue:cleanup CLEANUP_TIME=86,400

will clear processed queue items processed longer than 86,400 seconds ago (1 day)
