To conserve space in the database, create a cleanup task on Windows or a cleanup job on Linux and UNIX.
To mask stored procedures, Dynamic Data Masking dynamically creates tables and temporary stored procedures in a temporary database that you define in the accelerator security rules. After the Rule Engine applies masking rules to the SQL statement, it creates a temporary stored procedure and sends the request to the tables in the temporary database. If you do not create a cleanup job, you must manually drop the tables and stored procedures in the temporary database.
