The Table Cleaner feature in ServiceNow helps delete old or unwanted data in batches, ensuring minimal impact on performance. To create a new Table Cleaner, go to sys_auto_flush_list.do, click New, and complete required fields like Table Name, Matchfield (e.g., sys_created_on), and Age in seconds. You can set conditions for deletion or remove all records of a specified age. Finally, click Submit to save and activate the rule, which will run with the next Table Cleaner job.
