[jira] [Created] (ARROW-8933) [C++] Reduce generated code in vector_hash.cc

Wes McKinney created ARROW-8933:
-----------------------------------

             Summary: [C++] Reduce generated code in vector_hash.cc
                 Key: ARROW-8933
                 URL: https://issues.apache.org/jira/browse/ARROW-8933
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney
             Fix For: 1.0.0


Since hashing doesn't need to know about logical types, we can do the following:

* Use same generated code for both BinaryType and StringType
* Use same generated code for primitive types having the same byte width

These two changes should reduce binary size and improve compilation speed
