UUID v4 — Random

Fully random 128-bit identifier. Best general-purpose choice for database primary keys, session IDs, and correlation IDs.

UUID v7 — Time-ordered

Embeds a millisecond-precision Unix timestamp in the high bits, making UUIDs sortable by creation time. Ideal for indexed database columns where insert order matters.
