                        ObjectId id)
        Adds a snapshot to batch. Optionally stores the object id for the snapshot. Note that snapshot can hold either the real values or the instances of java.util.Supplier that will be resolved to the actual value on the spot, thus allowing deferred propagated keys resolution.
