Ask HN: 실제 UUID v4 충돌을 겪었습니다...

The occurrence of UUID v4 collisions in small datasets highlights that the perceived statistical safety of identifiers relies entirely on high-quality entropy sources, which are often compromised by hardware or software bugs. This incident underscores the importance of implementing collision handling or adopting more robust distributed ID generation strategies in high-reliability systems to prevent catastrophic data overlaps.
