                 Key: ARROW-17088
                 URL: https://issues.apache.org/jira/browse/ARROW-17088
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
    Affects Versions: 8.0.0

Related to ARROW-17072

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 {{write_dataset}} function, the default extension is {{.feather}} when {{feather}} is selected as the format, and {{.ipc}} when {{ipc}} is selected.
