How to disable making arrow tables in load_dataset ?
People mainly want this feature either because it takes too much time too make arrow tables, or they occupy too much memory on the disk. I think both the problem can be solved if we provide arrow tables themselves on datasets hub. Can we do this currently @lhoestq ? 

Is there a way to disable the construction of arrow tables, or to make them on the fly as the dataset is being used ?
