Row too big to be stored in cache
Seen with https://huggingface.co/datasets/elena-soare/crawled-ecommerce

at least one row is too big (~90MB) to be stored in the MongoDB cache:

```
pymongo.errors.DocumentTooLarge: BSON document too large (90954494 bytes) - the connected server supports BSON document sizes up to 16793598 bytes.
```

We should try/except the code here with the `pymongo.errors.DocumentTooLarge` exception:
