Wes McKinney commented on ARROW-9927:
-------------------------------------
In short, easier said than done. However, it would be good to have a tracking
JIRA for dplyr feature coverage. We have issues covering much of the essential
C++ query engine work but no idea on timeline when individuals will be able to
complete the work.

> Hi,
>
> The open_dataset() function in the R arrow package already includes the
> support for dplyr filter, select and rename functions. However, it would be a
> huge improvement if it also could include other functions such as group_by,
> summarise and mutate before calling collect(). Is there any idea or projet
> going on to do so ? Would be it possible to include those features
> (compatible also with dplyr version < 1) ?
> Many thanks for this excellent job.
