Scheduled Jobs

This bundle also allows you to have scheduled jobs which are executed in certain intervals. This can either be achieved by implementing JMS\JobQueueBundle\Command\CronCommand in your command, or implementing JMS\JobQueueBundle\Cron\JobScheduler in a service and tagging the service with jms_job_queue.scheduler.

The jobs are then scheduled with the jms-job-queue:schedule command that is run as an additional background process. You can also run multiple instances of this command to ensure high availability and avoid a single point of failure.

Implement CronCommand

class MyScheduledCommand extends ContainerAwareCommand implements CronCommand
{
    // configure, execute, etc. ...

    public function shouldBeScheduled(\DateTime $lastRunAt)
    {
        return time() - $lastRunAt->getTimestamp() >= 60; // Executed at most every minute.
    }

    public function createCronJob(\DateTime $lastRunAt)
    {
        return new Job('my-scheduled-command');
    }
}

For common intervals, you can also use one of the provided traits:

class MyScheduledCommand extends ContainerAwareCommand implements CronCommand
{
    use ScheduleEveryMinute;

    // ...
}

Implement JobScheduler

This is useful if you want to run a third-party command or a Symfony command as a scheduled command via this bundle.

class MyJobScheduler implements JobScheduler
{
    public function getCommands(): array
    {
        return ['my-command'];
    }

    public function shouldSchedule($commandName, \DateTime $lastRunAt)
    {
        return time() - $lastRunAt->getTimestamp() >= 60; // Executed at most every minute.
    }

    public function createJob($commandName, \DateTime $lastRunAt)
    {
        return new Job('my-command');
    }
}
