takaaki7 opened a new issue, #43494: URL: https://github.com/apache/arrow/issues/43494
### Describe the enhancement requested Currently, when struct itself is null, child's validity is unknown. So client must compute AND of those bitmaps to know child's validity. I think inlining parent validity into child validity is more effective for query engines. ### Component(s) Format -- This is an automated message from the Apache Git Service.
