Gearman Driver

This driver works with Gearman queues.

Configuration example:

return [
    'bootstrap' => [
        'queue', // The component registers its own console commands
    ],
    'components' => [
        'queue' => [
            'class' => \yii\queue\gearman\Queue::class,
            'host' => 'localhost',
            'port' => 4730,
            'channel' => 'my_queue',
        ],
    ],
];

Console

Console commands are used to process queued tasks.

yii queue/listen

listen command launches a daemon which infinitely queries the queue. If there are new tasks they're immediately obtained and executed. This method is most efficient when command is properly daemonized via supervisor or systemd.

yii queue/run

run command obtains and executes tasks in a loop until queue is empty. Works well with cron.

run and listen commands have options:

• --verbose, -v: print executing statuses into console.
• --isolate: each task is executed in a separate child process.
• --color: highlighting for verbose mode.
