Thanks for reporting this @rafapereirabr! It looks like this isn't a bug, but a difference between how data.table and tibble print these kinds of numbers. I tried that example but passing the results into `dput()` to print the underlying objects, and the values were identical: ``` r library(arrow) #> #> Attaching package: 'arrow' #> The following object is masked from 'package:utils': #> #> timestamp library(dplyr) #> #> Attaching package: 'dplyr' #> The following objects are masked from 'package:stats': #> #> filter, lag #> The following objects are masked from 'package:base': #> #> intersect, setdiff, setequal, union library(data.table) #> #> Attaching package: 'data.table' #> The following objects are masked from 'package:dplyr': #> #> between, first, last options(scipen = 9999) # create sample data df <- data.frame(tipo = 1, id =23232308, vinc = 99930010917577) df$tipo <- as.integer(df$tipo) df$id <- as.numeric(df$id) df$vinc <- bit64::as.integer64(df$vinc) fwrite(df, 'test.csv') # check csv data.table::fread('test.csv') %>% dput() #> structure(list(tipo = 1L, id = 23232308L, vinc = structure(0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000493719853829155, class = "integer64")), row.names = c(NA, #> -1L), class = c("data.table", "data.frame"), .internal.selfref = <pointer: 0x576171e05370>) test <- arrow::open_csv_dataset('test.csv') dplyr::collect(test) %>% dput() #> structure(list(tipo = 1L, id = 23232308L, vinc = structure(0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000493719853829155, class = "integer64")), class = c("tbl_df", #> "tbl", "data.frame"), row.names = c(NA, -1L)) arrow::write_parquet(df, 'test.parquet') test2 <- arrow::open_dataset('test.parquet') collect(test2) %>% dput() #> structure(list(tipo = 1L, id = 23232308, vinc = structure(0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000493719853829155, class = "integer64")), row.names = c(NA, #> -1L), class = c("tbl_df", "tbl", "data.frame")) ``` <sup>Created on 2024-05-03 with [reprex v2.1.0](https://reprex.tidyverse.org)</sup> -- This is an automated message from the Apache Git Service.
