Thanks for the comment. In the article I actually show both approaches: Python 3.14’s uuid.uuid7() first, mostly for completeness, and then the recommended one where PostgreSQL 18 generates the UUIDv7 itself using the native uuidv7() function. The DB-side version is already the default path I suggest for anything beyond a simple local setup.

Regarding the timestamp, a dedicated column generated by the database from uuid_extract_timestamp() can be very practical in Django. It is written at insert time by PostgreSQL, defined declaratively in the model with GeneratedField, and handled entirely by the ORM without relying on triggers. It also makes filtering, ordering or using the Django admin faster and simpler, since querying on a proper datetime field avoids extra annotations or computation on the UUID expression.

If you have a reference for UUIDv7 support in MSSQL I’d really appreciate it, ideally from the official documentation. I’m also curious to know from which version it is available and whether the current Django MSSQL backend exposes it already.

I think it depends on the use case. When strict ordering of records from multiple processes is not super important and when you also need the UUID7 for other things, it may be more practical (and/or performant) to let the client compute the UUID7.

So, as usual, “it depends”. ;-)

Thanks for pointing this out and for sharing the link.
