Why it is worth using UUID identifiers in a database?
The article discusses the advantages of using UUIDs as identifiers in database tables. A UUID, or universally unique identifier, presents several benefits over traditional numeric primary keys. Firstly, due to their uniqueness, UUIDs eliminate the risk of collisions that may arise when using sequential numbers. Secondly, UUIDs are better suited for distributed systems, where data can be generated in various locations. Another significant advantage is that UUIDs are unpredictable, which may enhance the application's security by making it difficult to guess subsequent identifiers. Properly understood, UUIDs can also affect database performance, although not directly. In summary, the use of UUIDs in database tables offers numerous benefits that can facilitate application development and increase their security.
