Technical conferences and community events have increasingly featured sessions on UUID design, especially as UUID v7 gained RFC status in 2024. Below is a curated list of past events where UUID topics were covered — from PostgreSQL conferences exploring native uuidv7() support, to cloud-native and language-specific meetups addressing identifier strategy in distributed systems.
Each entry links to the official event site for further reference, along with an internal coverage page summarizing the UUID-related content from that event.
Recent events
PGConf.EU 2024
UUID v7 as the New Default for PostgreSQL Primary Keys
Sessions at PGConf.EU 2024 covered UUID v7 as a drop-in replacement for UUID v4 primary keys, the upcoming uuidv7() built-in function in PostgreSQL 18, and migration strategies for production schemas.

KubeCon + CloudNativeCon NA 2024
Distributed Identifier Strategies for Cloud-Native Systems
Salt Lake City, Utah
KubeCon NA 2024 talks on distributed tracing and microservice identity explored UUID v7 as a coordination-free identifier with built-in temporal ordering — a practical improvement over random v4 for event correlation.
-
DjangoCon US 2024
UUID Primary Keys in Django — Moving from v4 to v7
Durham, North Carolina
DjangoCon US 2024 sessions addressed UUID primary key performance in Django projects, comparing uuid4 and uuid7 defaults, and how Python 3.13's new uuid.uuid7() changes the recommended setup for new Django applications.

GopherCon 2024
UUIDs in Go — v7 Support in google/uuid 1.6
Chicago, Illinois
GopherCon 2024 covered the google/uuid package's addition of uuid.NewV7() in version 1.6, patterns for GORM and pgx integration, and when to choose v7 over v4 for database primary keys in Go services.
Frequently asked questions
Have there been conference talks about UUID v7?
Yes. UUID v7 has been covered at PGConf.EU, KubeCon, DjangoCon, and GopherCon since RFC 9562 was published in 2024. Talks have focused on the B-tree index performance improvement over UUID v4, the PostgreSQL 18 native uuidv7() function, and migration patterns for existing schemas.
Was UUID v7 discussed at PostgreSQL conferences?
Yes. PGConf.EU 2024 included sessions on UUID v7 as a replacement for UUID v4 primary keys in PostgreSQL, covering the B-tree index behaviour, the upcoming PostgreSQL 18 uuidv7() function, and practical migration steps. The PostgreSQL global events calendar lists upcoming conferences where these topics continue to be discussed.
Should I use v4 or v7?
Use v7 for database primary keys (time-sortable, index-friendly) and v4 for anything where creation order could leak information, like tokens or share links.
