SmartConnect allows the retrieval of only the information that has changed or amended inside Extender. This is achieved by auditing the changes to Extender tables using database level triggers.
When a map, built using an Extender change data source is run, it will automatically mark the tracking rows as processed to make sure that the same row is not processed more than once.
