In this video, we explain the potential problems with UUIDs, the widely used standard for unique identifiers. We talk about the most common problems, such as database performance and storage issues, and discuss scenarios where UUIDs may not be the best choice.
But I won't leave you with mere problems. We'll explore practical solutions, including ULID and UUID v7, that address some of the drawbacks of traditional UUIDs. I'll show you how to choose the right unique identifier strategy for your specific needs, whether you stick with UUIDs or switch to an alternative. If you work with unique identifiers, this video is a must-watch. It will help you make informed decisions based on a balanced understanding of UUIDs and their alternatives.
