> Add Label Name Swap Feature
> ---------------------------
>
> Key: S2GRAPH-12
> URL: https://issues.apache.org/jira/browse/S2GRAPH-12
> Project: S2Graph
> Issue Type: New Feature
> Reporter: Hyunsung Jo
> Labels: feature
>
> 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.
