I trying to delete over 20,000,000 objects at once by executing:
MyModel.objects.filter(some_field__lt=100).delete()
But I can’t, because of not enough memory (1GB VPS). Is it bad method or what? How to do it?
In this case I think it’s better to use raw sql query https://docs.djangoproject.com/en/dev/topics/db/sql/#executing-custom-sql-directly
