Why is UUID v7 better than UUID v4 for databases?

UUID v4 is completely random, causing costly B-Tree page splits and index fragmentation in PostgreSQL and MySQL. UUID v7 embeds a 48-bit millisecond timestamp, ensuring sequential ordered inserts while maintaining 128-bit global uniqueness.

Can I decode the exact creation date from a UUID v7?

Yes. The first 48 bits encode the UNIX epoch timestamp in milliseconds. Our built-in inspector decodes and displays the exact creation date, time, and milliseconds.
