A possible workaround is to use context.clear_cache() and gc.collect() on get method.

def get(self):

    for _ in range(10):
        for entity in DummyModel.query().iter():
            pass # Do whatever you want
    self.response.headers['Content-Type'] = 'text/plain'
    self.response.write('Hello, World!')
    context = ndb.get_context()
    context.clear_cache()
    gc.collect()
