Remarks
This delegate is passed to ReplicaMetadata.GetFilteredChangeBatch to perform filtered synchronization. The metadata storage service calls this delegate one time for each item change that is detected during change detection. When the delegate is called, it can inspect the item change metadata and indicate whether the change should be included in the change batch.
