The job queue in MediaWiki is a system designed to handle tasks that are too time-consuming or resource-intensive to be performed during a normal web request-response cycle.
The job queue allows MediaWiki to defer tasks that do not need immediate execution. This includes operations like updating link tables when templates change, sending notification emails, re-rendering pages after template edits, or any batch processing tasks.
