--------------------------------------

             Summary: [C++] Consider using fast-double-parser
                 Key: ARROW-10328
                 URL: https://issues.apache.org/jira/browse/ARROW-10328
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou
             Fix For: 3.0.0


We use Google's double-conversion library for parsing strings to doubles. We should consider using this library, which is more than 2x faster.

Parsing doubles is important for CSV performance.
