Description: 

The DrupalQueue system was refactored to use a different factory, for consistency with other similar subsystems (cache, db).

Drupal 7

<?php
$queue
= DrupalQueue::get('update_fetch_tasks');
?>

Drupal 8

<?php
$queue
= Drupal::queue('update_fetch_tasks');
?>

By default, the queue service uses the queue.database implementation, which can be controlled by the following $settings in settings.php:

queue_reliable_service_' . $name: A reliable queue for the $name queue
queue_service_' . $name: A queue for the $name queue
queue_default: The default queue backend service, defaults to queue.database
