> To bring up a new site or recover a failed site, I need an inter-site state transfer mechanism for synchronizing keys.
> Note that initially, this should a manual process that is invoked on one site to one of its configured backups.
> This should be based on the non-blocking state transfer mechanism for consistency.  
> The pseudo-design may look similar to the following:
> - Manually invokable, background thread
> - Since the bridge end is open, there are writes happening to keys.  Keep track of the puts/removes on the main data owner.
> - Iterate through the key set.
> - If the key has already been modified since the process started, discard.
> - Else synchronously write the key value in a TX context
