In the world of modern software development, unique identifiers play a crucial role in database management and application design. With the introduction of UUID version 7 (UUID v7) in recent technology stacks, developers now have a more efficient way to generate unique identifiers. This article will guide you through implementing UUID v7 generation in Spring Boot entities using custom annotations, specifically with Hibernate 6.5+ and Spring Boot 3.3+.

Understanding UUID v7: A Quick Overview

Before diving into the implementation, let’s understand what makes UUID v7 special. Unlike previous UUID versions, UUID v7 combines:

  • Timestamp-based generation
  • Improved randomness
  • Better performance for database indexing

Traditional UUIDs often suffered from performance issues in database operations. UUID v7 addresses these challenges by creating identifiers that are:

  • Chronologically sortable
  • More database-friendly
  • Globally unique
