My oro_audit table is 4.007.603 and oro_audit_field 27.211.076 records big. I need to purge some old records and was hoping to get some of the best known methods for this task. Can i delete them directly from the database?
Out of the box, there are no methods to automatically remove old audit data.
You can purge old records manually from the database tables or create a cron command to run it on time basis.
