[jira] [Created] (ARROW-10313) [C++] Improve UTF8 validation speed and CSV string conversion

Antoine Pitrou created ARROW-10313:
--------------------------------------

             Summary: [C++] Improve UTF8 validation speed and CSV string conversion
                 Key: ARROW-10313
                 URL: https://issues.apache.org/jira/browse/ARROW-10313
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou
             Fix For: 3.0.0


Based on profiling from ARROW-10308, UTF8 validation is a bottleneck of CSV string conversion.

This is because we must validate many small UTF8 strings individually.
