def queryset_generator(queryset, chunksize=1000):
    """ 
    Iterate over a Django Queryset ordered by the primary key

    This method loads a maximum of chunksize (default: 1000) rows in its
    memory at the same time while django normally would load all rows in its
    memory. Using the iterator() method only causes it to not preload all the
    classes.

    Note that the implementation of the generator does not support ordered query sets.

    Both directives have three optional arguments: ``height``, ``width``
    and ``align``. Default height is 281 and default width is 500.
