A high-performance unique numeric ID generator library implementing an optimized Snowflake ('drift') algorithm, natively available in C#, Java, Go, Rust, C, JavaScript, TypeScript, Python, Pascal, and more via FFI. It generates short, monotonically increasing 64-bit IDs suitable for distributed database primary keys, with automatic WorkerId registration in container environments like Kubernetes.
Use cases
- generate unique primary keys for distributed databases
- generate short snowflake-style IDs that fit in JavaScript Number
- generate unique IDs across sharded databases
- auto-register worker IDs when scaling in kubernetes
- generate monotonic IDs at very high concurrency
- replace GUIDs with shorter sortable numeric IDs
- handle clock rollback when generating IDs
When to choose
- you need compact, time-ordered numeric IDs for distributed systems or sharded tables
- you need extremely high ID generation throughput (hundreds of thousands per second)
- you want a dependency-free ID generator usable across many programming languages
- you deploy in containers and need automatic WorkerId registration
- you need to keep generated IDs within JavaScript's Number.MAX_SAFE_INTEGER for decades
When to avoid
- you need UUID/GUID-format identifiers or string IDs
- you require strictly consecutive (gap-free) sequential IDs
- your system cannot guarantee a globally unique WorkerId per instance
- you depend on an external service like Redis for ID allocation and prefer that model
