Delta processing allows you to synchronize identities faster by processing only data that has changed in the source and target connected systems since the last synchronization run.
By offering both full synchronization or quick delta processing methods between two data systems, Synchronization Service provides you the flexibility of choosing the appropriate method for your synchronization tasks.
NOTE: This feature is only supported by certain data systems. For more information, see the relevant data connector documentation in the Active Roles Synchronization Service Administration Guide.
