Starting from the 5.3.3 version, X-Cart can perform some long-processing tasks (such as email sending and image resizing) asynchronously, increasing the UI responsiveness and speeding up the store operations.
Please note that this feature is experimental and may be unstable.
As of now, the background jobs queue speeds up the following actions:
Order operations (placing, changing shipping and payment statuses, updating via AOM);
Any other actions which involve an email sending;
Amazon S3 image transfer.
You can enable the job queueing by setting the following config option in the etc/config.php file:
[queue] backgroundJobsSchedulingEnabled = true
After this, X-Cart will push every job to the message queue instead of executing on the stop. There are several ways of executing jobs placed on this queue:
Cron Task
If you have configured your server to run scheduled X-Cart tasks, X-Cart will process the job queue at the next cron run. Therefore, we advise scheduling cron tasks for the shortest period possible, e.g., 5 - 10 minutes.
Console Application
In case you to control the queue processing via an external script, you can start queue processing by running the following command in the X-Cart working dir:
php console.php --target=consumer --action=consumeAll
Browser Execution
You can also control and process pending jobs via the X-Cart Admin area page -admin.php?target=jobs. To be able to run this page, your X-Cart config should have the following option under the [queue] section:
jsRunnerForOnlineEnabled = true
This option is enabled by default in X-Cart 5.3.3.
