Hi everyone,
I’ve just published a detailed article on using UUIDv7 across Python 3.14, Django 5.2 and PostgreSQL 18, including examples with db_default, GeneratedField, native PostgreSQL functions and a note on UUIDv47 for safer public identifiers.

You can read it here:

I can’t understand - what you want say - here

  • SQLite or non PostgreSQL databases are used

and that

Use PostgreSQL uuidv7 when:

SQLite can this. too

  • the database is responsible for generating identifiers
  • multiple writers insert rows concurrently
  • you want to expose creation time using uuid_extract_timestamp
  • sequential inserts improve performance

Why not

non PostgreSQL

In the basic set Python from 3.12 we can see uuid4.
In which the python’s version we will can see the uuid7? :slight_smile:

Python 3.14: as I wrote in my original post and in the article. But if it’s not too clear I can add a clarification.
