![]() ![]() Also, it allows you to group tasks in categories called channels, and define default settings for all the tasks under those channels.It has an option to force run any task in the list, in case you can’t wait for the next automated execution of that task.When it runs, it completely ignores tasks that don’t have to be ran at that time, making it more efficient from the performance standpoint.The Migrate Cron Scheduler module provides the functionality of executing the migrations on cronjob with option flags set at a particular time interval. It allows you to customize the schedule of every task, similar to a cron tab, where some tasks are executed every given minutes, others once a day, others once a week, etc. This means the module no longer has a dependency to migratetools and can now be used with Drupal 9+ and drush 10.4+.Also, say that you need to execute only one task every 15 minutes, you have to configure that value globally and apply it to all tasks to achieve that goal.Įlysia cron module is a solution to those problems, these are some of its benefits: On another note, Drupal cron doesn’t allow you to configure the task schedule in a granular way, hence all tasks are executed at the same time, leading to performance issues if you have too many expensive tasks in the list. With no visitors, the default Drupal cron won’t run. * Used to grab functionality from the container.Drupal 7 cron out of the box is kind of inefficient, because it depends on users visiting your website to trigger the action to verify if it’s time to be ran and execute all the background tasks scheduled in Drupal. You don't need to worry about removing the item from the queue once finished, this will be done for you. You can then access each property of the object and process the queue item as you need too. ![]() But you should bring in the functionality as needed.įinally add a function for processItem, which takes one parameter which is the queue item. ![]() In my below example queue worker, I am bringing in the Entity Type Manager and Database Connection functionality into the class via dependency injection. ![]() If there are still items to process, then when the cron job runs again, the queue worker will process some more and it will keep doing this until all items have been processed. The full class is below, but I want to first draw attention to an annotation towards the top of the class, this tells Drupal that we are adding a queue worker with the item of custom_queue, the human name of Custom Queue and that on cron, the queue worker should process as many items as it can in 60 seconds. In our example, the class would be called CustomQueue.php. Now inside your module, create a src folder with a folder called Plugin inside, then inside that folder create another folder called QueueWorker. Now create a new php file that will contain your queue worker php class. Worker plugins are used by some queues for processing the individual items in the queue. The queue worker generally processes items on cron, but you can use drush to work through the queue items. 2 Answers Sorted by: 2 Copied from \Drupal\Core\Annotation\QueueWorker, the annotation and placd where the QueueWorker annotation is documented. First of all, what are queue workers, they are designed to work through each item in the queue that the worker is assigned to and applies the supplied logic to each item as needed. ![]()
