Auto Cascades

Auto Cascades

An auto cascade masks the primary key in a parent table and related foreign keys in child tables with the same value.
Tables with key constraints have auto cascades applied by default. You can manually disable or enable auto cascades. For example, you need to mask the employee ID in an employee master table and two child tables. The employee ID is a primary key in the master table. When you mask the employee ID in the employee table, the employee ID in the child tables receives the same masked value.
To use auto cascades, key constraints must exist between the parent and the child tables.
You cannot use auto cascades for XSD, MongoDB, and Cassandra data sources.
