Replying to [comment:6 Aaron Blair]:
Can you guide me on how you set up your unit test and what your test
output looked like, if possible? I have attached my test suits and test
output, please let me know if there is anything I need to modify. Thank
you in advance and sorry for being inactive for a long time.

> Install MySQL Cluster server v8.0.28 onto multiple (say 3) servers and
start replication.
> Install Django (any version that uses cursor.execute("CREATE TABLE
ROLLBACK_TEST (X INT)") in django.db.backends.base.features.py this exists
on 4.1 but it was there for several versions previous to 4.1 as well)
> Create any model that uses autocreate id as pk (ie do not specify an id
or pk field)
> Write any unit test bases on django.test.TestCase for the model which
accesses the db
> Run the unit test
