For a light version of the query, you can try a qs.first() as Django will
limit the SQL request to the first element.

What about introspecting the model associated with the QuerySet:
qs = SomeModel.objects.all()
columns = [f.column for f in qs.model._meta.fields]

How to get names of columns from QuerySet without executing
The closes I can get with this is the following:
comp = queryset.query.get_compiler(DEFAULT_DB_ALIAS)
fields = [alias or sql.split('.')[1] for _, (sql, _), alias in
comp.get_select()[0]]

How to get names of columns from QuerySet without executing it?
If it is not possible what would be the most easier way to execute a
lighter version of the query.
The query itself is unknown, it could be anything.
