Frank Du created ARROW-9398:
-------------------------------
Summary: [C++] Register the SIMD sum variants under function
instance instead a SIMD function
Key: ARROW-9398
URL: https://issues.apache.org/jira/browse/ARROW-9398
Project: Apache Arrow
Issue Type: Improvement
Reporter: Frank Du
Assignee: Frank Du
Per the review comments of [https://github.com/apache/arrow/pull/7607]
"Instead, we should add all the kernel variants to the same {{Function}}
instance and then the {{Dispatch*}} methods should select the kernel with the
maximum SIMD level as set on the Kernel object. That was the idea of the
{{simd_level}} parameter"
We should delegate the SIMD sum kernels to function instance
