Join us on a fascinating deep dive into UUIDs (Universally Unique Identifiers)! While UUIDs might look like simple strings of characters, there's much more complexity beneath the surface. In this episode, we explore the origins, limitations, and advancements of UUID versions-from the timestamp-based V1 to the popular random V4, and the powerful new V6, V7, and customizable V8. Learn why certain UUIDs are optimized for databases, how to choose the right version for your application, and essential best practices such as not storing UUIDs as text. Whether you're building distributed systems or just curious about backend architecture, this guide equips you to leverage UUIDs effectively in your projects.
