- { host: redis.example.com }
sqs:
class: Riverline\WorkerBundle\Provider\AwsSQS

amqp: ## WIP
class: Riverline\WorkerBundle\Provider\AMQP
semaphore:
class: Riverline\WorkerBundle\Provider\Semaphore
queues:
queue1:
name: ThisIsMyQueue
provider: predis
queue2:
name: https://eu-west-1.queue.amazonaws.com/xxxxxx/xxxx
provider: sqsYou can access any configured provider or queue through the Symfony Container
<?php
$provider = $this->get('riverline_worker.provider.predis');
$provider->put('ThisIsMyQueue', 'Hello World');
$queue = $this->get('riverline_worker.queue.queue1');
echo $queue->count()." item(s) in the queue";You can easily create Workers
<?php
// src/Acme/DemoBundle/Command/DemoWorkerCommand.php
namespace Acme\DemoBundle\Command;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;
use Riverline\WorkerBundle\Command\Worker;
class DemoWorkerCommand extends Worker
{
protected function configureWorker()
{
$this
// Queue name from the configuration
->setQueueName('queue1')
// Inhered Command methods
->setName('demo-worker')
->setDescription('Test a worker')
;
}
protected function executeWorker(InputInterface $input, OutputInterface $output, $workload)
{
$output->writeln($workload);
}
}Then you can launch your worker like any other command
$ php app/console demo-worker
Hello WorldYou can pass queue configurations.
$ php app/console --worker-wait-timeout=60 --worker-limit=10 --worker-exit-on-exceptionThis command wait 60 seconds for a workload from the queue, will process a maximum of 10 workloads and exit if the executeWorker() throw an exception
