wuid
An extremely fast globally unique number generator that produces 64-bit integers using Redis, MySQL, MongoDB, or custom callbacks.
What is wuid?
WUID is a universal unique identifier generator designed for high-performance applications. It generates sequential 64-bit integers, with the high 28 bits loaded from a data source like Redis, MySQL, or MongoDB, ensuring uniqueness across distributed instances. It solves the need for extremely fast, distributed, and sequential ID generation without the overhead of traditional UUIDs.
Developers building distributed systems, microservices, or high-throughput applications that require fast, unique, and sequential identifier generation, such as those using Go for backend services.
Developers choose WUID for its extreme performance—capable of generating 100 million IDs per second per instance—and its flexibility in supporting multiple data sources for distributed uniqueness, offering a lightweight, lock-free alternative to slower UUID implementations.
