Just like the 'sync' or 'deferred' connection, this is not a real queue. It is always fired immediately. The only difference is that the closure is sent to the background without waiting for the response. This package is more usable as an alternative for running incidental tasks in the background, without setting up a 'real' queue driver. It is similar to the 'deferred' connection, but it runs in a background process, so might be more suitable for long running tasks.
Note: Since v0.8 this uses the Concurrently::defer() method instead of the database queue. No database migrations tables are required now. The config can be simplified as below.
Require the latest version of this package with Composer
composer require barryvdh/laravel-async-queue
You should now be able to use the async driver in config/queue.php. Use the same config as for the database, but use async as driver.
'connections' => array(
    ...
    'async' => array(
        'driver' => 'async',
    ),
    ...
}
Set the default to async, either by changing to config or setting QUEUE_DRIVER in your .env file to async.
It should work the same as the sync driver, so no need to run a queue listener. Downside is that you cannot actually queue or plan things. Queue::later() is also fired directly. For more info see http://laravel.com/docs/queues
