Xid
xid is a distributed unique identifier library designed to generate compact, globally unique, and k-sortable identifiers. It functions as a stateless generator that creates identifiers without requiring a central coordinator or network synchronization between instances.
The project converts binary identifiers into human-readable, case-insensitive Base32 strings, making the output suitable for use in URLs and web applications. It ensures uniqueness across different processes and hosts by combining high-resolution timestamps with machine identifiers.
These identifiers are designed for use as database primary keys to improve indexing and lookup performance. The system supports distributed systems coordination and backend scaling by providing identifiers that maintain approximate chronological order.
Features
