Dewey Dunnington commented on ARROW-18359:
------------------------------------------
I'm not sure if this is covered by one of the subtasks, but really huge binary
arrays take forever to print...I am guessing because it tries to convert the
entire binary array to a string before selecting the few characters that will
actually be shown:
{code:R}
library(arrow)
#> Some features are not enabled in this build of Arrow. Run `arrow_info()` for
more information.
#>
#> Attaching package: 'arrow'
#> The following object is masked from 'package:utils':
#>
#> timestamp
really_big_raw <- raw(1e9)
really_big_binary <- Array$create(list(really_big_raw), type = binary())
system.time(really_big_binary$ToString())
#> user system elapsed
#> 12.396 1.660 14.269
{code}
(I ran into that one because the current encoding for geospatial data in
Parquet files is {{binary()}} and the elements can be huge)
