shortid enables the generation of short, fully unique IDs, suitable for various applications requiring identifiers. This Go package is inspired by the node.js shortid library and is designed for high-throughput ID generation. It leverages a sophisticated algorithm to ensure uniqueness and guarantees ID lifespan until 2050.
This project stands out due to its remarkable speed and concurrency safety, allowing hundreds of thousands of IDs to be generated per second. It features a fixed ID size and a long lifespan, addressing common limitations of other ID generation methods. The Go implementation prioritizes stability and performance through concurrency-safe design and avoids reliance on yearly resets.
- High Performance: Generates IDs at a rate of hundreds of thousands per second, suitable for demanding applications.
- Concurrency Safe: Designed to handle concurrent ID generation without collisions, ensuring reliable operation.
- Long Lifespan: Guarantees unique IDs for 34 years (until 2050) within a single application instance.
- Fixed ID Size: Maintains a consistent ID length of 9-11 symbols, even under heavy load.
- Worker Support: Allows for multiple worker IDs, enabling independent ID sequences for different processes or users.
- Concurrency: Supports up to 32 workers, each providing unique sequences.
- Extensible: Provides options to adjust randomness for different application requirements, impacting ID length and lifespan.
shortid is a mature and stable project with a proven track record. The library has been actively maintained since its creation in 2016, demonstrating ongoing support and updates. Numerous tests, including concurrency and performance tests, ensure the reliability and correctness of the ID generation process. The project boasts a significant number of stars and forks, indicating community interest and adoption.
This project is beneficial for developers needing to generate large volumes of unique identifiers. It addresses use cases such as session IDs, database keys, and API request identifiers. By providing high performance, concurrency safety, and guaranteed uniqueness, shortid simplifies ID management and reduces the risk of collisions compared to alternative methods.
