> Operating live services on S2Graph, there are a few cases where interchanging two label names could come in handy.
> For example, assume that a social graph is being served under the label name _A_, and an updated graph has been loaded to _A'_.
> It would be nice if one can refer to the updated data of _A'_ while still making requests to the same label name _A_ so that no client-side code change is required.
> Obviously, this feature should have transaction support.
