INSERT INTO some_audit_table (&hellip;) COMMIT</p> <p>Does the SQL properly increment global status variables, etc?</p> <p>Also your triggers access the information schema a lot. Consider reading from STATUS_VARIABLES/GLOBAL_VARIABLES and pulling multiple values at once. The entire structure is materialized when you access the table so you might as well access as much data as you can in one pass.</p>
