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

             Summary: [C++] nonstd::string_view conflicts with std::string_view 
in c++17
                 Key: ARROW-5404
                 URL: https://issues.apache.org/jira/browse/ARROW-5404
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Benjamin Kietzman
            Assignee: Benjamin Kietzman


>From GitHub issue https://github.com/apache/arrow/issues/4294

Our vendored string_view header will forward to {{std::string_view}} if that is 
available. This can produce ABI conflicts and build errors when arrow or 
applications which use it are built against c++17.

I think it's acceptable to just force usage of nonstd's implementation with 
{{#define nssv_CONFIG_SELECT_STRING_VIEW nssv_STRING_VIEW_NONSTD}}
