The Quiet Bottleneck in Your Symfony App: Fragmented Indexes and Random UUIDs In the monolithic era, id INT AUTO_INCREMENT was the undisputed king of database identifiers. It was simple, small (4 bytes) and naturally sorted. But as we moved toward distributed systems, microservices...

However, creating a secondary UUIDv4 index to hide UUIDv7's timestamp negates its performance gains. Alternative? Encrypting UUIDv7 or using format-preserving encryption (FPE) can offer a middle ground. #UUIDs 4/5

UUID v4 collision risk is very low for practical numbers, but depends on a high-quality random number generator. A good RNG is key to maintaining uniqueness guarantees. #UUIDs 3/6
