What is a UUID
A UUID is a globally unique identifier used to label records, requests, or entities without collisions in distributed systems.
- Choose how many UUIDs you need.
- Generate a batch and copy one or all values.
- Use UUIDs as IDs in databases, APIs, and logs.
UUID v4 values are random and statistically unique. They are useful when you need IDs without relying on incremental counters.
