Yu Zhu updated ARROW-18370:
---------------------------
Affects Version/s: 10.0.0
Description:
`ds.write_dataset` allows specifying Parquet compression, for example:
```
import pandas as pd
import pyarrow as pa
import pyarrow.dataset as ds
df = pd.DataFrame(\{'a': [1, 2, 3], 'b': [4, 5, 6]})
df = pa.Table.from_pandas(df)
ds.write_dataset(
df,
base_dir='test',
format='parquet',
file_options=ds.ParquetFileFormat().make_write_options(compression='snappy'))
```
However, such tick (the `file_options` argument) doesn't work for feather, as
the following code gives me an error:
```
import pandas as pd
import pyarrow as pa
import pyarrow.dataset as ds
df = pd.DataFrame(\{'a': [1, 2, 3], 'b': [4, 5, 6]})
df = pa.Table.from_pandas(df)
ds.write_dataset(
df,
base_dir='test',
format='feather',
file_options=ds.FeatherFileFormat().make_write_options(compression='uncompressed'))
```
The error: `TypeError: FeatherFileFormat.make_write_options() takes no keyword
arguments`
Environment: Ubuntu 22.04
> [Python] `ds.write_dataset` doesn't allow feather compression
