Snowflake is a distributed unique ID generation service designed to produce non-colliding, time-ordered identification numbers at high scale. It functions as a scalable ID issuer that creates distinct entity identifiers across multiple server nodes to avoid coordination bottlenecks. The system utilizes stateless identifier coordination, calculating unique IDs through a deterministic mathematical formula rather than relying on a central database to track the last issued number. This approach allows it to generate identifiers for distributed database primary keys and high-scale transaction trac

This project is a distributed unique ID generator designed to produce 64-bit globally unique and sortable identifiers across multiple nodes. It implements a Snowflake-compatible algorithm that prevents collisions by combining timestamps, worker identifiers, and sequence numbers into a single integer. The system includes a worker ID orchestrator to allocate and maintain unique machine identities during instance startup and migration using database-backed strategies. To increase request throughput and reduce latency, it utilizes a ring-buffer caching layer that pre-generates identifiers and emp

Leaf is a distributed unique ID generation system that provides two distinct modes for producing identifiers across multiple application instances without central coordination. It offers both a database-backed segment mode, which allocates blocks of IDs from a database table and caches them in memory for high throughput, and a Snowflake-style mode that combines timestamps, worker identifiers, and sequence counters to produce time-sortable unique IDs. The system distinguishes itself by offering dual-mode generation through a single RESTful endpoint, allowing applications to choose between segm

ksuid is a Go implementation of k-sortable unique identifiers. It provides a system for generating globally unique identifiers that maintain a natural chronological order based on their generation timestamp. The project enables the creation of unique keys across distributed systems without a central coordinator. These identifiers are designed for use as database primary keys to maintain index performance and insert efficiency. The library includes capabilities for identifier serialization and parsing, allowing conversion between binary, text, and SQL formats. It also provides command-line to
