I have databases with over 750k entries using UUID for each row and have never ran into a collision -- over a 2 year period.

How do you know you've never had a collision? Are you checking, if so how?

And are you using Data::UUID? On Windows?

If you're using this to give every new record a unique id, why aren't you using an autoincrmenting primary key?
