>                 Key: ARROW-9657
>                 URL: https://issues.apache.org/jira/browse/ARROW-9657
>             Project: Apache Arrow
>          Issue Type: New Feature
>          Components: R
>            Reporter: Neal Richardson
>            Priority: Major
>              Labels: dataset
>
> Among the features:
> * ignore_prefixes option
> * Pass an explicit list of files + base directory
> * Exclude invalid files (boolean) option
> An important use case this would allow/fix is being able to open_dataset("really_really_big_file.csv") so you can partition/write it.
