viirya opened a new issue, #1962: URL: https://github.com/apache/arrow-rs/issues/1962
**Describe the bug** `null_count` of `DictionaryArray` calls the default implementation which gets null count of its `data` member. So basically it looks at the null count of keys. If a corresponding value of a key is null, `null_count` cannot get correct null count. `is_null` and `is_valid` also have same issue. **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.
