Moving away from UUIDs

2/18/2023

In this blog post, the author discusses the drawbacks of using universally unique identifiers (UUIDs) as identifiers in software systems and suggests alternative approaches. The author argues that while UUIDs are widely used and provide uniqueness, they have certain limitations that can negatively impact performance, storage, and usability. The post explores the issues with UUIDs, such as random access patterns, lack of determinism, and lack of human-readability. The author suggests using more structured identifiers, such as sequential IDs or hash-based identifiers, that can offer better performance and usability in certain scenarios. Overall, the blog post presents a thoughtful exploration of the limitations of UUIDs and offers alternative solutions to consider in software development.
