Simple replication is often used when a read only version of an existing datastore is needed or a remote hot backup is desired. The Apply Engine provides an easy to implement simple replication solution requiring very few instructions. It will also automatically detect out of sync conditions that have occurred due to issues outside of SQData's control and perform compensation by converting updates to inserts (if the record does not exist in the target), inserts to updates (if the record already exists in the target) and drop deletes, if the record does not exist in the target.
Note: This section assumes two things: First, that the environment on the target platform fully supports the type of datastore being replicated. Second, that a Connect CDC (SQData) Change Data Capture solution for the source datastore type has been selected, configured and tested.
