Generating unique, sequential business document IDs is a common challenge in enterprise applications. This article presents a robust solution using Redis atomic increments combined with daily resets and a three-layer deduplication mechanism. The approach ensures ID uniqueness even under high concurrency, handles daily rollovers cleanly, and prevents duplicate IDs through multiple validation layers. For backend developers and architects, this pattern offers a scalable and reliable alternative to database sequences or UUIDs, especially in distributed systems. The implementation leverages SpringBoot's integration with Redis, making it easy to adopt in existing projects. While the code is specific to SpringBoot, the design principles apply broadly to any system requiring ordered, unique identifiers with temporal partitioning.
