tustvold opened a new issue, #4689: URL: https://github.com/apache/arrow-rs/issues/4689
**Describe the bug** <!-- A clear and concise description of what the bug is. --> Currently various constructs containing nested `Field` validate that the nullability of their children matches that of the schema. This helps to avoid subtle bugs that could result in data loss / corruption, see #4602 for more context on this. Currently this is achieved by inspecting the null count of the child array, however, for dictionaries this is potentially incorrect as the null count of the parent only reflects the null count of the keys, and not the logical null count. **To Reproduce** <!-- Steps to reproduce the behavior: --> **Expected behavior** <!-- A clear and concise description of what you expected to happen. --> **Additional context** <!-- Add any other context about the problem here. --> -- This is an automated message from the Apache Git Service.
