[jira] [Created] (ARROW-3320) [C++] Improve float parsing performance

Antoine Pitrou created ARROW-3320:
-------------------------------------

             Summary: [C++] Improve float parsing performance
                 Key: ARROW-3320
                 URL: https://issues.apache.org/jira/browse/ARROW-3320
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 0.10.0
            Reporter: Antoine Pitrou


According to the {{number-parsing-benchmark}}, parsing integers from strings currently runs at around ~1.6M items/sec. (on Ubuntu 18.04). We should be able to do better. This will be important for CSV parsing performance.
