"Toujours en UUIDv4/v5 ? Il est encore temps de migrer pour scaler votre base relationnelle !" avec Brice Jaglin et Axel Czarniak. Voyons ensemble comment l’adoption des UUIDv7 permet à votre base PostgreSQL critique d'éviter le mur du scale vertical. #SunnyTech2026 #UUIDv7
@0xlelouch_ Las llaves primarias #UUID no solo son para cross-system.
También son para idempotencia, procesamiento distribuído con tolerancia al traslape y resolución de conflictos en los algoritmos de reunificación.
Para que tus índices no se fragmenten tanto, debes preferir usar #UUIDv7.
UUID v7: time ordered IDs (timestamp + random) boost inserts, cut index fragmentation, and pair with keyset pagination; binary(16) storage can halve space. #UUIDv7

"UUIDv7...Suitable as a primary key in high write environments."
"UUIDv7 improves...by adding a timestamp prefix that makes identifiers sort in creation order"

Unlike random UUID v4, UUID v7 embeds time, making IDs sortable, database-friendly, and globally unique.
✅ Time-ordered
✅ Better index performance
✅ Customizable timestamps
Generate via Guid.CreateVersion7()
Perfect for distributed systems.

@WallisDev Los índices sobre campos #UUID se vuelven una pesadilla porque son tan dispersos que acabas teniendo que trepar el índice completo a memoria. También presenta problemas de amplificación de la escritura (basada en bloques).
El uso de #UUIDv7 ayuda bastante con esos dos problemas.
A short summary of the differences between UUIDv4 and #UUIDv7 and an idea how it could be implemented in #Oracle #database. A UUID datatype would be nice 😉.

I'm trying to collect real-world performance differences between #UUIDv7 (and #ULID) and standard #UUIDv4 primary keys for both #sqlite and #PostgreSQL in my application.
Despite a week of solid effort, many tests, and loads of data, I cannot observe a measurable difference. 🙃
