How to Implement Distributed ID Generation with Segment Mode? A Double‑Buffer Issuer in Practice

The article analyses lock contention caused by per‑request ID generation, derives a segment‑based solution that batches IDs using a configurable step, defines a left‑closed/right‑open interval schema in MySQL, and builds a double‑buffer Java issuer with asynchronous pre‑loading, thorough concurrency handling, testing, and configuration guidelines.
