One of the new feature that’s being developed with SQL Server 2016. If you are a DBA then you will like this feature very much. In the real world when you move the data from production to development or uat server we are supposed to obfuscate the data so that the developer wont see the actual live data. Till SQL Server 2016 we are achieving this with dynamic DML scripts which will mask the data. Based on the volume of records in the database we will end up long wait hours to obfuscate it.
