GaussDB Kernel database objects include DATABASE, USER, SCHEMA, and TABLE. You can change the value of this parameter to audit only the operations on required database objects. In scenarios where a standby node is forcibly elected as primary, you are advised to set audit_system_object to the maximum value and audit all DDL objects. Improper modification of this parameter will cause loss of DDL audit logs. Contact the customer service to change the parameter value."
