Why version 7?
UUID v7: time ordering and privacy
The same UUID format, with a timestamp up front.
When should I choose UUID v7?
Consider v7 for database identifiers where time ordering and index locality matter. Its first 48 bits encode a Unix millisecond timestamp. Check that your database and libraries support it.
Does UUID v7 reveal its creation time?
Yes. Its timestamp can be read from the identifier. Choose UUID v4 if you do not want an embedded generation time. Neither version is a substitute for an authentication secret.
