Should be slightly better now:
``` r
library(arrow, warn.conflicts = FALSE)
#> See arrow_info() for available features
library(tidyverse)
library(bench)
options(width = 120)
bench::workout({
df <- data.frame(col_letters = sample(LETTERS, 22180168, replace = TRUE))
write_parquet(df, "df.parquet")
df_rt <- read_parquet("df.parquet")
write_parquet(df_rt, "df_again.parquet")
})
#> # A tibble: 4 × 3
#> exprs
