UUID v4Default cho database row IDs khi không cần sort theo thời gian. 128-bit random.

UUID v7Nên dùng cho DB primary key — sortable theo timestamp, btree index hiệu quả. Mới (RFC 9562, 2024).

ULID26 ký tự, base32 Crockford (không có I, L, O, U). Sort theo time, copy-paste an toàn (case insensitive).

NanoIDURL-safe, ngắn hơn UUID. 21 char = entropy ~126 bits. 12 char = ~74 bits (đủ cho 10M IDs).
