Represents methods that the metadata storage service can call to determine whether to include an item in a change batch.
interface IChangeBatchCallback : IUnknown
Indicates whether the specified item should be included in a change batch.
This callback interface is passed to IReplicaMetadata::GetFilteredChangeBatch to perform filtered synchronization. The metadata storage service calls OnAddingItemToBatch one time for each item change that is detected during change detection. When OnAddingItemToBatch is called, it can inspect the item change metadata and indicate whether the change should be included in the change batch.
