GUIDs / UUIDs are the most widely supported identifiers across databases, APIs and programming languages. However, some high-scale distributed systems use Snowflake ID (Twitter's identifier format) as an alternative to achieve compact 64-bit storage, time-ordering and distributed generation with machine coordination.
For the safest, standards-based choice, use GUID / UUID v4 (fully random) or GUID / UUID v7 (time-ordered for databases). Consider Snowflake ID only when you operate at very large scale and have infrastructure for machine coordination.
