The Unique Key Check additional parameter is used to determine whether the Rules Engine must perform unique key checks in the case of non-manual data entry, for example sql-script() functions. Allowed values are:

In this case, unique key checks are still performed by the RDBMS so that data integrity is ensured. For data entered manually, unique key checks continue to be performed by the Rules Engine.
When to use
Set this parameter to False only in time-critical situations where overall performance is a real issue.
