SHIMA Tatsuya created ARROW-17089:
-------------------------------------
Summary: [Python] Use `.arrow` as extension for IPC file dataset
Key: ARROW-17089
URL: https://issues.apache.org/jira/browse/ARROW-17089
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Affects Versions: 8.0.0
Reporter: SHIMA Tatsuya
Same as ARROW-17088
As noted in the following document, the recommended extension for IPC files is
now `.arrow`.
> We recommend the “.arrow” extension for files created with this format.
https://arrow.apache.org/docs/format/Columnar.html#ipc-file-format
However, currently when writing a dataset with the
{{pyarrow.dataset.write_dataset}} function, the default extension is
{{.feather}} when {{arrow}} or {{ipc}} or {{feather}} is selected.
