Hi,

By looking at the indexes set for the table usr_preferences, it appears that UUID is going to be unique against the attribute column.
So if user A has a attribute of custom_parameter_Z and user B has the same attribute, then both UUIDs need to be different, right?
UUID can really be anything right? Its set to VARCHAR(64), so heck - a MD5 checksum against say a epoch timestamp would be fine.
I just want to confirm how unique each row (in respects to the UUID) it needs to be.

Thanks,
