I benchmarked it too...the difference is very small:
``` r
# remotes::install_github("apache/arrow/r#11652")
library(arrow, warn.conflicts = FALSE)
library(dplyr, warn.conflicts = FALSE)
df <- RecordBatch$create(integers = 1:1e7, doubles = as.numeric(1:1e7))
bench::mark(
df %>% mutate(integers %/% 2L) %>% collect(),
df %>% mutate(doubles %/% 2L) %>% collect(),
check = FALSE
)
#> # A tibble: 2 × 6
#> expression min median `itr/sec`
mem_alloc
#> <bch:expr> <bch:tm> <bch:tm> <dbl>
<bch:byt>
#> 1 df %>% mutate(integers%/%2L) %>% collect() 26.1ms 26.6ms 36.4
162MB
#> 2 df %>% mutate(doubles%/%2L) %>% collect() 24.8ms 25.8ms 38.2
191MB
#> # … with 1 more variable: gc/sec <dbl>
