UUID Generation Workflow
Generate UUIDs for different use cases: database records, API idempotency keys, and correlation IDs.
이 레시피 활용 시점
UUIDs provide globally unique identifiers without central coordination. Essential for distributed systems, database primary keys, and API request tracking.

자주 묻는 질문
UUID v4 vs auto-increment IDs — which is better?
UUIDs are better for distributed systems (no coordination needed) and security (not guessable). Auto-increment is better for performance (smaller, sortable) in single-database setups.
Can UUIDs collide?
UUID v4 collision probability is astronomically low: you'd need to generate 2.71 quintillion UUIDs for a 50% chance. In practice, collisions don't happen.
