>
> Now that we can print an ExecPlan (ARROW-15016), we can investigate 
> unexpected outputs. With the following chunk of code:
> {code:r}
> mtcars %>%
>   arrow_table() %>%
>   select(mpg, wt, cyl) %>% 
>   filter(mpg > 20) %>%
>   arrange(desc(wt)) %>%
>   head(3) %>%
>   show_exec_plan()
> #> ExecPlan with 3 nodes:
> #> 2:SinkNode{}
> #>   1:ProjectNode{projection=[mpg, wt, cyl]}
> #>     0:SourceNode{}
> {code}
>  * FilterNode disappears when head/tail are involved +
>  * we do not have additional information regarding the OrderBySinkNode
>  * the entry point is a SourceNode and not a TableSourceNode
