Also reproducible with Python:
```python
import pyarrow as pa
import pyarrow.dataset as ds
tbl = pa.table({
'var_1': ("arrow", "arrow", "arrow"),
'var_2': ("arrow", "arrow", "arroW")
})
part = ds.partitioning(
pa.schema([("var_2", pa.string())]),
flavor="hive"
)
ds.write_dataset(tbl, "dataset_output", format="parquet", partitioning=part)
ds_out = ds.dataset("dataset_output")
```
Only one partition is written:
```python
ds_out.files
# ['dataset_output/var_2=arroW/part-0.parquet']
```
```python
ds_out.to_table()
# pyarrow.Table
# var_1: string
# ----
# var_1: [["arrow"]]
```
