Yii2Queue. AMQP Interop driver

Note: This a copy of AMQP Interop doc from the yiisoft/yii2-queue repository.

The driver works with RabbitMQ queues.

In order for it to work you should add any amqp interop compatible transport to your project, for example enqueue/amqp-lib package.

Advantages:

• It would work with any amqp interop compatible transports, such as

  • enqueue/amqp-ext based on PHP amqp extension
  • enqueue/amqp-lib based on php-amqplib/php-amqplib
  • enqueue/amqp-bunny based on bunny
• Supports priorities
• Supports delays
• Supports ttr
• Supports attempts
• Contains new options like: vhost, connection_timeout, qos_prefetch_count and so on.
• Supports Secure (SSL) AMQP connections.
• An ability to set DSN like: amqp:, amqps: or amqp://user:pass@localhost:1000/vhost

Configuration example:

return [
    'bootstrap' => [
        'queue', // The component registers own console commands
    ],
    'components' => [
        'queue' => [
            'class' => \yii\queue\amqp_interop\Queue::class,
            'port' => 5672,
            'user' => 'guest',
            'password' => 'guest',
            'queueName' => 'queue',
            'driver' => yii\queue\amqp_interop\Queue::ENQUEUE_AMQP_LIB,

            // or
            'dsn' => 'amqp://guest:guest@localhost:5672/%2F',

            // or, same as above
            'dsn' => 'amqp:',
        ],
    ],
];

Console

Console is used to listen and 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.

listen command has options:

• --verbose, -v: print executing statuses into console.
• --isolate: verbose mode of a job execute. If enabled, execute result of each job will be printed.
• --color: highlighting for verbose mode.
