             Summary: [C++] Add a facility helper for SIMD runtime dispatch.
                 Key: ARROW-9717
                 URL: https://issues.apache.org/jira/browse/ARROW-9717
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Frank Du
            Assignee: Frank Du


During the discussion of [https://github.com/apache/arrow/pull/7940], It will has SIMD runtime path for different functions, it could be nice to have a SIMD dispatch facility helper instead handling it in each function.

 

The implementation should be performance friendly, resolver only need run one time.
