The LUYA admin module is required.

Since LUYA Admin version 2.0, the (Yii Queue component is automatically registered and configured properly and is ready to handle jobs. The queue is also known as scheduler in admin context.

The component is configured as adminqueue based on the Database yii\queue\db\Queue integration.

The admin module has a default integration for scheduling jobs when working with selects (dropdowns) and checkbox, so you are able to schedule those changes out of the box! See Checkbox (ToggleStatus) luya\admin\ngrest\plugins\ToggleStatus::$scheduling and Select luya\admin\ngrest\plugins\Select::$scheduling.

Configure to run

There are 3 different options to enable to adminqueue, by default the admin queue is not configured to process jobs unless activated.

  • "Fake Cronjob": On request in the frontend and admin the queue will be processed each 26 minutes.
  • Cronjob: Setup a cronjob which will run every minute (or less) to process the queue.
  • Realtime Listen: The queue/listen commands runs a seperate service and processed the queue in realtime.

"Fake Cronjob" (Auto Bootstrap Queue)

The fake cron job will run each 25 minutes whether users request the websites in the frontend or sites are visited in the administration area. This is called a "fake cronjob" and should not be taken for large queue jobs. So take into account that frontend users might visit the website and process the queue. In order to enable the fake cronjob set luya\admin\Module::$autoBootstrapQueue to true, in the admin module config:

'modules' => [
    'admin' => [
        'class' => 'luya\admin\Module',
        // ...
        'autoBootstrapQueue' => true,

The fake cronjob won't be executed on console (cli) commands. The information about last run timestamp is stored in luya\admin\models\Config with identifier luya\admin\models\Config::CONFIG_QUEUE_TIMESTAMP.

Cronjob (admin/queue Command)

In shared hosting enviroments the best usage for the admins queue scheduler system is to setup a cronjob which runs every 5 minutes (ary at any other frequents depending on your needs). Make sure that luya\admin\Module::$autoBootstrapQueue is disabled un setup a cronjob with runs the luya\admin\commands\QueueController as admin/queue command:

/vendor/bin/luya admin/queue

Realtime Listen

Since version 2.0.4 the native implementation of the Yii Queue is bootstraped, therefore you might run all the commands from the original component. The most common use case is to process the queue in realtime, therfore the queue/listen command is used:

./vendor/bin/luya queue/listen --verbose=1

The verbose option helps to debug and should be disabled in production.

The original queue/listen command won't store any timestamp information about last run in the luya\admin\models\Config like the fake cronjob does.

When using the queue/listen command its recommend to enable luya\admin\storage\BaseFileSystemStorage::$queueFilters because this option will process the image filter creation in the queue instead of the users browser. This will therefore moved the large memory load from the webserver to the instance which is running the queue/listen command. Add all your application [[/guide/app/filters]] to the luya\admin\storage\BaseFileSystemStorage::$queueFiltersList list, as only the listed filters will be generated.

Push a Job into the Queue

In order to push a certain job into the built in admin queue you can use Yii::$app->adminqueue->push(new MyCustomJob()) or if you like to delay the execution use for certain seconds, use Yii::$app->adminqueue->delay(3600)->push(new MySuperJob()).

The response from the push method is always the queue id, so you can check or store the status of the job with Yii::$app->queue->isDone($id).

Retry & Errors

The Queue is by default conigured to allow 5 retrys of an error job each 5 minutes. So assuming the exectued job fails (throws a luya\Exception for instance) the queue waits 5 minutes until a next try is executed. This will be repeated until 5 trys are processed, then the job will be removed from the queue with status failed.

An exception is therefore the expected error format to ensure the job will retry again. If the exception is part of your application ensure to surround the job logic with a try catch block.

Queue Image Filters

Since version 4.0 of Admin Module its possible to queue the generating of image filters, this means that when a new image is uploaded, the filter versions of this image will be created in the queue and not in realtime when the image is uploaded, this can usefull to remove the load from the webserver and move it to the queue application which is running. Here is an example config of the storage system to generate the listed filters in the queue:

$config->component('storage', [
    'class' => 'luya\aws\S3FileSystem',
    // ... more s3 config details
    // enable the queue filters
    'queueFilters' => true,
    // defines which filters should be created in the queue, its recommend to add the default filters and also maybe some project specific filters
    'queueFiltersList' => ['tiny-crop', 'medium-thumbnail', 'teaser', 'detail'],

See luya\admin\storage\BaseFileSystemStorage::$queueFilters for more details.
