Hi @eitsupi ,
Depending on your memory restrictions, you may need to control the batch
size (how many rows are loaded at once) on the scanner:
```python
import pyarrow.dataset as ds
input_dataset = ds.dataset("input")
scanner = inpute_dataset.scanner(batch_size=100_000) # default is 1_000_000
ds.write_dataset(scanner.to_reader(), "output", format="parquet")
```
Does that help in your use case?
