What is a UUID?
A UUID is a 128-bit identifier commonly used for database records, request IDs, distributed systems, test data, and client-generated object IDs. UUID v4 is random, so it does not require a central sequence generator.
Use the single generator for one ID, or batch generate up to 100 UUIDs when creating fixtures, migration scripts, or sample records.
FAQ
What format does UUID v4 follow?
The standard format is xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where the 4 marks version 4 and y marks the variant.
Are these UUIDs sequential?
No. UUID v4 values are random. They are useful when you want IDs without coordination, but not when you need sortable IDs.
