Symfony 2 Bundle for Eventio BBQ Library

Work in progress for Symfony2 Bundle for Eventio BBQ, Message Queue Abstraction Library for PHP.

Installation

Via composer.json

"require": {
    "eventio/bbq-bundle": "dev-master"
}

Configuration

Register the bundle in your AppKernel.php:

public function registerBundles()
{
    $bundles = array(
        // ...
        new \Eventio\BBQBundle\EventioBBQBundle(),
        // ...
    );
}

Configure each queue in your config.yml as follows:

eventio_bbq:
    queues:
        queue_id:
            type: directory
            directory: /tmp/directory

You can insert as many queues as you want below queues. See Queue Types below for detailed configuration reference.

Usage

After the bundle and queues are configured, access the BBQ instance and push/fetch jobs from the queues:

$bbq = $this->get('eventio_bbq'); // Instance of \Eventio\BBQ()
$bbq->pushJob('queue_id', 'Payload');

As each queue is registered as individual Symfony2 service, you can access them directly:

$queue = $this->get('eventio_bbq.queue_id'); // Instance of \Eventio\BBQ\Queue\DirectoryQueue();
$queue->pushJob(new StringPayload('Some payload'));

Queue Types

DirectoryQueue

type: directory

Parameters

• directory The directory acting as the queue storage

RedisTubeQueue

type: predis

Parameters

• key The Redis key for the queue
• predis_id The Predis connection id (default = default)
• config Further queue configuration (default = array())

Multiple Redis servers

Predis configuration can be customized under section predis_connections.

Default configuration (when nothing is defined) is as follows.

eventio_bbq:
    predis_connections:
        default:
            params: tcp://127.0.0.1:6379
            options: ~

Two different queues under different hosts could be configured like:

eventio_bbq:
    predis_clients:
        host1:
            params: tcp://192.168.1.1:6379
        host2:
            params: tcp://192.168.1.2:6379
    queues:
        queue1:
            predis_id: host1
            key: queue1_at_host1
        queue2:
            predis_id: host2
            key: queue2_at_host2

Usage of the two queues inside the application:

$bbq->pushJob('queue1', 'Job to redis server 1, queue "queue1_at_host1"');
$bbq->pushJob('queue2', 'Job to redis server 2, queue "queue2_at_host2"');

Master/Slave replication

params and options under predis_clients section are passed to \Predis\Client constructor as is. Therefore you can configure them freely, including master/slave setup:

eventio_bbq:
    predis_clients:
        master_slave:
            params: ["tcp://192.168.1.1:6379?alias=master", "tcp://192.168.1.2:6379?alias=slave"]
            options: [replication: true]
    queues:
        replicated_queue:
            predis_id: master_slave
            key: queue

See all possible Connection parameters (=params) and Client Options (=options)

PheanstalkTubeQueue

type: pheanstalk

Parameters

• tube The pheanstalk tube acting as the queue
• pheanstalk_id The pheanstalk connection id (default = default)

Multiple beanstalkd servers

Pheanstalk configuration can be customized under section pheanstalk_connections.

Default configuration (when nothing is defined) is as follows.

eventio_bbq:
    pheanstalk_connections:
        default:
            host: 127.0.0.1

Two different queues under different hosts could be configured like:

eventio_bbq:
    pheanstalk_connections:
        host1:
            host: 192.168.0.1
        host2:
            host: 192.168.0.2
    queues:
        queue1:
            pheanstalk_id: host1
            tube: tube_at_host1
        queue2:
            pheanstalk_id: host2
            tube: tube_at_host2

Usage of the two queues inside the application is simple:

$bbq->pushJob('queue1', 'Job to pheanstalk server 1, tube tube_at_host1');
$bbq->pushJob('queue2', 'Job to pheanstalk server 2, tube tube_at_host2');
