@abduazizR It looks like that issue is restricted to `right_join()` only -
see the reprex below:
``` r
library(arrow)
library(dplyr)
tbl <- tibble::tibble(x = 1:10, y = 1:10)
tbl2 <- tibble::tibble(y = 3:5, z = c("a", "b", "c"))
# right join using dplyr
tbl2 %>%
right_join(tbl)
#> Joining, by = "y"
#> # A tibble: 10 × 3
#> y z x
#> <int> <chr> <int>
#> 1 3 a 3
#> 2 4 b 4
#> 3 5 c 5
#> 4 1 <NA> 1
#> 5 2 <NA> 2
#> 6 6 <NA> 6
#> 7 7 <NA> 7
#> 8 8 <NA> 8
#> 9 9 <NA> 9
#> 10 10 <NA> 10
# right join using Arrow
tbl2 %>%
arrow_table() %>%
right_join(tbl) %>%
collect()
#> # A tibble: 10 × 3
#> y z x
#> <int> <chr> <int>
#> 1 3 a 3
#> 2 4 b 4
#> 3 5 c 5
#> 4 NA <NA> 1
#> 5 NA <NA> 2
#> 6 NA <NA> 6
#> 7 NA <NA> 7
#> 8 NA <NA> 8
#> 9 NA <NA> 9
#> 10 NA <NA> 10
# left join using dplyr
tbl %>%
left_join(tbl2)
#> Joining, by = "y"
#> # A tibble: 10 × 3
#> x y z
#> <int> <int> <chr>
#> 1 1 1 <NA>
#> 2 2 2 <NA>
#> 3 3 3 a
#> 4 4 4 b
#> 5 5 5 c
#> 6 6 6 <NA>
#> 7 7 7 <NA>
#> 8 8 8 <NA>
#> 9 9 9 <NA>
#> 10 10 10 <NA>
# left join using Arrow
tbl %>%
arrow_table() %>%
left_join(tbl2) %>%
collect()
#> # A tibble: 10 × 3
#> x y z
#> <int> <int> <chr>
#> 1 3 3 a
#> 2 4 4 b
#> 3 5 5 c
#> 4 1 1 <NA>
#> 5 2 2 <NA>
#> 6 6 6 <NA>
#> 7 7 7 <NA>
#> 8 8 8 <NA>
#> 9 9 9 <NA>
#> 10 10 10 <NA>
