Generate Universally Unique Lexicographically-sortable Identifiers (ULIDs). ULIDs are a modern alternative to UUIDs, designed to be time-sortable, URL-safe, and highly unique.
ULIDs are excellent for use as primary keys in distributed databases. Their time-based nature ensures that new records can be sorted chronologically without needing a separate timestamp column, which simplifies queries and can improve performance. They are also URL-safe and case-insensitive, making them ideal for use in APIs and web applications.
