-------------------------------+--------------------
I could not find a note how the migrations operations (for example
CreateModel) handle transactions.
I checked these pages:
https://docs.djangoproject.com/en/dev/topics/migrations/
https://docs.djangoproject.com/en/dev/ref/migration-operations/
There are some notes about how RunPython handles transactions, but not the
general handling of transactions.
The question which I want to see answered in the docs:
> Do migrations operations create a new transaction by default, or do all
migrations operations run in one transaction?
Please forgive me, if I was blind.

Comment:
Yes, this isn't stated clearly. There's a hint about it in the MySQL
section of the topic guide, "MySQL lacks support for transactions around
schema alteration operations" and some discussion in the
[https://docs.djangoproject.com/en/stable/howto/writing-migrations/
writing migrations how-to], but it should be more clear in general.

Oracle also lacks support of transactions around schema alteration
operations.
