How to get the last element as fast as possible in Django?

Question

JavaScript

Hello everyone
There is a model of about 1000 records, new elements are constantly added to the tail. The task is to get the id-number of the last element as quickly as possible.

test = Test.objects.all().order_by('-id')[0].id

test = Test.objects.all().last().id

They don't work as fast as I would like. Is there a faster way?

Answer 1

In both cases, a query c must be generated
. speed uvas here depends only on the database.
And for acceleration in a database - the index on this field is necessary.
