Subject [jira] [Created] (ARROW-711) [C++] Remove extern template declarations for NumericArray<T> types

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

             Summary: [C++] Remove extern template declarations for NumericArray<T>
types
                 Key: ARROW-711
                 URL: https://issues.apache.org/jira/browse/ARROW-711
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Wes McKinney
            Assignee: Wes McKinney


It seems that linkers have diverging semantics around visibility when using the {{extern template}}
declaration (see linker errors in https://ci.appveyor.com/project/ApacheSoftwareFoundation/arrow/build/1.0.841).
Since the only thing impacted right now is the {{NumericArray<T>}} constructor, removing
these doesn't seem too onerous. I ran the existing benchmarks and looked at the library sizes
before and after, and there doesn't appear to be a meaningful difference.
