How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
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 d
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 an implementation of the ULID standard in the Go programming language. It provides tools for generating universally unique, lexicographically sortable identifiers that combine millisecond timestamps with random data. The library ensures that identifiers maintain chronological order through alphabetical sorting. It includes a monotonic generator to guarantee that multiple identifiers created within the same millisecond are produced in a strictly increasing sequence. The project covers unique identifier generation and database primary key optimization. It also provides a comman
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
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.
