[Kamailio-Users] UUID column in usr_preferences - How unique does it need to be?

[Graham Wooden]

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,

-graham
