In the documentation section regarding UUIDFields (, we have:

Universally unique identifiers are a good alternative to AutoField for primary_key

However the question of whether UUIDs make good primary keys regarding to performance appears to be debated:

What is the take of the community regarding that?

In any case if there is doubt, having mention of that in the documentation should be considered.

What is the take of the community regarding that?

The DevelopersMailingList is the appropriate venue for this kind of question/discussion.

There was some discussion of this here: which led to #31007.

I cannot recall exactly what the consensus opinion on using UUID PKs was. (I've certainly done it in the past without experiencing particular issues but...)

Will close as invalid for now, since the mailing list is the place for it, but happy to re-open/accept if there's a consensus reached.
