Hello. In the past I’ve been able to download prior Common Voice releases using `common_voice` and the version number, but `mozilla-foundation/common_voice_8_0` seems to give me memory issues.
The code snippet below downloads the dataset just fine but uses up all available memory in a Colab High-RAM environment when preparing the train set:
```python
dataset = datasets.load_dataset("mozilla-foundation/common_voice_8_0",
"en",
use_auth_token="my_auth_token",
split="train")
```
It’s the English dataset so this will take time to download. I reduced the `writer_batch_size` in the hopes that it will work but no luck ☹
Any help would be greatly appreciated!

Pinging @lhoestq because this could be related to [this issue](https://github.com/huggingface/datasets/issues/4057) maybe?

Hi ! On which version of `datasets` do you have this issue ? and which version of `pyarrow` ?

Sorry, should have provided that first.
`datasets` was installed from `master` so the version is `2.0.1.dev0`, the `pyarrow` version is `6.0.1`.

Thanks ! I was able to reproduce with datasets 2.0.0 and pyarrow 6.0.1 on colab, I’ll investigate

Hi @lhoestq, don’t mean to be a pain but were you able to find the cause of this? Thanks!
