--------------------------------------

I chat I had with Tom Jenkinson:

clebert: tomjenkinson: but now you have compatibility issues to deal
[08:56am] clebert: tomjenkinson: what if you start a new version...
[08:56am] clebert: you didn't have the data there.. then you will add it

[08:56am] clebert: tomjenkinson: you would have to only set the UUID if there is no data folder.. no Objects pending at all

[08:57am] clebert: tomjenkinson: well.. you can easily do a check on.. if (objects.counts() == 0) and ID=default, ID = new UUID, store it on the folder and recover on restart

> It shouldn't be needed to assign the node-id manually IMO.
> You could store the node-id on a file and recover it for subsequent starts.
> On hornetQ for instance, we look for the nodeID on a file, if the file doesn't exist we assign a UUID and write to the file.
> In our previous experience UUID would be a best fit to assign the nodes since that was the only way we could guarantee unique IDs between the nodes.
