Is dataset iterative or not?
`datasets.Dataset` objects are both iterative and mapping types: it has both `__iter__` and `__getitem__`
For example you can do
```python
for example in dataset:
    # do something
```
or
```python
for i in range(len(dataset)):
    example = dataset[i]
    # do something
```
When you do that, one and only one example is loaded into memory at a time.
Hi
I want to use your library for large-scale training, I am not sure if this is implemented as iterative datasets or not?
could you provide me with example how I can use datasets as iterative datasets?
thanks
