Using phpMyAdmin, i noticed my tcm_grade_items_history table is HUGE at 949.9 MB and is by far the largest table I have.
Have I missed an important setting somewhere? Is this table supposed to be this large?
Help me tame the beast, please!
There are some admin settings relating to the retention of Grade Histories on the "cleanup" page.
Navigate to /admin/settings.php?section=cleanup
Depending upon version of Moodle ... there are Scheduled Task that one could run individually. Site Admin search for 'task'.
Also, how often are you running cron? Run the cron and watch for info related to target of 'cleaning up'. Could run cron from the web but must give a password now ... search for 'cron'.
