v1	v2
6	6	Does anyone have an opinion which would be preferable?
7	7
8		There's also currently a performance impact of recording migrations outside a transaction. I have a squashed migration that `replaces=[...]` several hundred others. `record_migration` inserts a `django_migrations` row for each of those replacements. It's taking about 0.6s to record all of them applied, because the each get their own transaction. In a single transaction, it takes about 0.01s.

I'm working on making my tests run faster, and since they migration from scratch every time that's actually a significant part of time to migrate--slower than even the combine DDL time of all the migrations.
