[jira] [Created] (ARROW-8477) [C++] Enable reading and writing of long filenames for Windows

TP Boudreau created ARROW-8477:
----------------------------------

             Summary: [C++] Enable reading and writing of long filenames for Windows
                 Key: ARROW-8477
                 URL: https://issues.apache.org/jira/browse/ARROW-8477
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: TP Boudreau
            Assignee: TP Boudreau
         Attachments: long_path.cc

Parquet file path lengths are limited to ~260 characters in Windows environments.  For example, the attached program runs successfully on Linux (provided the nested directories already exist), but fails on Windows.

Replacing the currently used _wsopen() functions with their Win32 analogues fixes this.  A patch is forthcoming.
