QuerySet API reference | Django documentation | Django

QuerySet API reference | Django documentation | Django: "In some complex data-modeling situations, your models might contain a lot of fields, some of which could contain a lot of data (for example, text fields), or require expensive processing to convert them to Python objects. If you are using the results of a queryset in some situation where you know you don’t need those particular fields, you can tell Django not to retrieve them from the database."
