What Is UUIDv7?
UUIDv7 is a modern version of the universally unique identifier (UUID) standard designed for time-based, sortable identifiers. Unlike traditional UUIDv4 (random) or UUIDv1 (MAC-based), UUIDv7 embeds a 48-bit Unix timestamp with millisecond precision, making each ID both globally unique and chronologically sortable. This makes it ideal for high-performance databases, distributed systems, and event logging.
