> 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
