UUID v4
UUID (Universally Unique Identifier) v4 is a 128-bit identifier generated from cryptographically secure random numbers. It is guaranteed to be unique with overwhelming probability. UUIDs are written in the form xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx and are the industry standard for unique record identifiers.
ULID
ULID (Universally Unique Lexicographically Sortable Identifier) is a 128-bit identifier that encodes a millisecond-precision timestamp in the first 10 characters, followed by 16 random characters. Unlike UUID, ULIDs sort lexicographically by creation time, making them efficient for use as database primary keys.
