Time-Ordered IDs
Version 1 UUIDs are generated from a timestamp and a node ID. Because they are time-based, successive IDs generated on the same machine are monotonic and useful for sorting.
Space-Time Uniqueness
By combining a high-resolution timestamp with a unique hardware identifier (or random node), v1 UUIDs provide a robust guarantee of uniqueness across distributed systems.
