[jira] [Commented] (ARROW-9927) [R] Add dplyr group_by, summarise and mutate support in function open_dataset R arrow package

["Wes McKinney (Jira)" <ji...@apache.org>]

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.
