[jira] [Created] (ARROW-5775) [C++] StructArray : cached boxed fields not thread-safe

Antoine Pitrou created ARROW-5775:
-------------------------------------

             Summary: [C++] StructArray : cached boxed fields not thread-safe
                 Key: ARROW-5775
                 URL: https://issues.apache.org/jira/browse/ARROW-5775
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
    Affects Versions: 0.13.0
            Reporter: Antoine Pitrou


The lazy initialization isn't thread-safe (it relies neither on a lock nor on an atomic).

Perhaps we need a more general "cached property" facility to handle these cases.
