[jira] [Commented] (ARROW-3239) [C++] Improve random data generation functions

["Antoine Pitrou (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-3239?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16616369#comment-16616369 ] 

Antoine Pitrou commented on ARROW-3239:
---------------------------------------

And/or perhaps a RandomState-like API.
{code:c++}
auto rand = RandomState(seed);
auto arr = rand.int32_array(length);
auto arr = rand.varbinary_array(length, {min_value_size, max_value_size});
{code}

> Our various code for generating random datasets for testing and benchmarks is a bit verbose / awkward.
> I suggest defining a nicer API so we can write code like:
> {code}
> auto arr = random::int32(length, seed);
> auto arr = random::varbinary(length, max_value_size, seed);
> {code}
> Since this is only for test code, we can abort if anything returns error Status to make the API more convenient
