31785	Documentation suggesting using UUIDField as a good alternative for primary_key, without inviting to consider performance drawbacks	Remy	nobody	"In the documentation section regarding UUIDFields ([https://docs.djangoproject.com/en/3.0/ref/models/fields/#uuidfield]), 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: https://www.percona.com/blog/2019/11/22/uuids-are-popular-but-bad-for-performance-lets-discuss/

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.
