I think this is a great use case for combining `arrow` and `duckdb`.
There is no support for slice_* functions in `arrow` and `duckdb` does not
yet have the ability to open a dataset.
```r
library(arrow)
library(dplyr)
tf <- tempfile()
dir.create(tf)
nycflights13::flights |>
group_by(month) |>
write_dataset(tf)
df <- open_dataset(tf, hive_style = TRUE) |>
group_by(month) |>
to_duckdb() |>
slice_sample(n = 2) |>
collect()
```
