-------------------------------------
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.
