What is the ULID Generator?

A ULID (Universally Unique Lexicographically Sortable Identifier) is a 26-character identifier that encodes a timestamp in its first 10 characters and entropy in the last 16. This makes them lexicographically sortable.

Q: Why choose ULID?

Unlike UUIDs, ULIDs can be sorted chronologically because they start with a millisecond timestamp prefix, improving database indexing.
