Requirements
Installation
First, install SlmQueue (instructions here). Then,
add the following line into your composer.json
file:
"require": { "slm/queue-amq": "0.4.*" }
Then, enable the module by adding SlmQueueAmq
in your application.config.php file. You may also want to
configure the module: just copy the slm_queue_amq.local.php.dist
(you can find this file in the config
folder of SlmQueueAmq) into your config/autoload folder, and override what you want.
Documentation
Before reading SlmQueueAmq documentation, please read SlmQueue documentation.
(Don't forget to first install Active MQ, and to run the daemon program on the server)
Setting the connection parameters
Copy the slm_queue_amq.local.php.dist
file to your config/autoload
folder, and follow the instructions.
Adding queues
A concrete class that implements the SlmQueue interface for Active MQ is included
as SlmQueueAmq\Queue\AmqQueue
and a factory is available to create the queue.
Therefore, if you want to have a queue called "email", just add the following line in your
module.config.php
file:
return array( 'slm_queue' => array( 'queue_manager' => array( 'factories' => array( 'email' => 'SlmQueueAmq\Factory\AmqQueueFactory' ) ) ) );
This queue can therefore be pulled from the QueuePluginManager class.
Operations on queues
push
Valid options are all constants on the SlmQueueAmq\Queue\AmqQueueInterface
interface:
AmqQueueInterface::DELAY
: the delay in milliseconds before a job become available to be popped (defaults to no delay)AmqQueueInterface::PERIOD
: in milliseconds, how much time a job can be running for before it's put back into the queueAmqQueueInterface::REPEAT
: the number of times the job should be repeatedly available (defaults to 1, no repeating jobs)AmqQueueInterface::CRON
: a CRON string to schedule the job via cronAmqQueueInterface::PERSIST
: set to true to send a persistent message
Example:
use SlmQueueAmq\Queue\AmqQueueInterface as Amq; $queue->push($job, array( Amq::CRON => '0 * * * *', Amq::DELAY => 1000, Amq::PERIOD => 1000, Amq::REPEAT => 9 ));
The above code will deliver the job 10 times, with a one second delay between each job, and this will happen every hour. See more explaination about the options in the Active MQ manual.
pop
Valid option is:
- timeout: by default, when we ask for a job, it will block until a job is found (possibly forever if new jobs never come). If you set a timeout (in seconds), it will return after the timeout is expired, even if no jobs were found
Executing jobs
SlmQueueAmq provides a command-line tool that can be used to pop and execute jobs. You can type the following command within the public folder of your Zend Framework 2 application:
php index.php queue amq <queue> [--timeout=]
The queue is a mandatory parameter, while the timeout is an optional flag that specifies the duration in seconds for which the call will wait for a job to arrive in the queue before returning (because the script can wait forever if no job come).
