> 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.

> 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.
