ULID (Universally Unique Lexicographically Sortable Identifier) is a fast, robust alternative to UUID. It offers lexicographical sortability, enhancing database indexing and making it ideal for time-series data. With a compact 128-bit representation, ULIDs are URL-safe and human-readable, utilizing Crockford's Base32 encoding. The package ensures collision resistance even when generated rapidly, providing unique IDs across distributed systems and various applications where predictable ordering is critical.
