Topology synchronization is triggered whenever there is a change in topology of an underlying domain. But SAM may import only a subset of the topology from the underlying domain based on dxa configuration. As a result, topology synchronization may be triggered even though the imported topology has not changed in the underlying domain. Such topology synchronizations are not useful as no change is propagated to SAM and can be avoided by disabling autosync mode. Instead topology synchronizations can be triggered manually at regular intervals. One of the easiest ways to identify redundant syncs is to find out number of instances added or deleted during topology synchronizations. If it is zero, then it is likely that redundant syncs are triggered between SAM and underlying domain.
