Leaf
A high-performance distributed ID generation service offering segment and snowflake algorithms, used internally at Meituan-Dianping.
What is Leaf?
Leaf is a distributed ID generation service that provides unique identifiers for applications in a service-oriented architecture. It solves the problem of generating scalable, high-performance IDs by offering two modes: segment mode for database-backed range allocation and snowflake mode for decentralized, time-ordered IDs. It is designed to meet the demands of large-scale production systems with low latency and high throughput.
Developers and architects building distributed systems, microservices, or high-traffic applications that require reliable, unique ID generation without single points of failure.
Developers choose Leaf for its proven performance in production at Meituan-Dianping, its flexibility in supporting multiple ID generation strategies, and its ability to handle high QPS with minimal latency, making it a robust alternative to ad-hoc ID solutions.
