------------------------------
External issue URL: https://github.com/apache/arrow/issues/21192
> [C++] Consolidate random string generators for use in benchmarks and unittests
> ------------------------------------------------------------------------------
>
> Key: ARROW-4661
> URL: https://issues.apache.org/jira/browse/ARROW-4661
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Reporter: Hatem Helal
> Priority: Minor
>
> This was discussed in here:
> [https://github.com/apache/arrow/pull/3721]
> For testing/benchmarking dictionary encoding its useful to control the number
> of repeated values and it would also be good to optionally include null
> values. The ability to provide a custom alphabet would be handy for
> generating strings with unicode characters.
>
> Also note that a simple PRNG should be used as the group has observed
> performance trouble with Mersenne Twister.
