--------------------------------------
Summary: [C++] Check nullability when validating fields on batches
or struct arrays
Key: ARROW-15961
URL: https://issues.apache.org/jira/browse/ARROW-15961
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Antoine Pitrou
Fix For: 8.0.0
According to ARROW-15899, it is possible to declare a field non-nullable,
associate with data that has nulls, and still pass validation.
Validation should instead fail in such a situation (at least full validation,
since computing the null count can be O(n)).
