[jira] [Created] (ARROW-10797) [C++] Investigate faster random generation for tests and benchmarks

Antoine Pitrou created ARROW-10797:
--------------------------------------

             Summary: [C++] Investigate faster random generation for tests and benchmarks
                 Key: ARROW-10797
                 URL: https://issues.apache.org/jira/browse/ARROW-10797
             Project: Apache Arrow
          Issue Type: Wish
          Components: C++
            Reporter: Antoine Pitrou


Test and benchmark harness sometimes has a non-trivial cost when generating large random data (e.g. {{vector_sort_benchmark.cc}}). We may try a non-standard PRNG such as [PCG|https://www.pcg-random.org/using-pcg-cpp.html].
