I don't think this is correct, as @HaoYang670 describes, the null count and validity is only determined by the keys. If a key is valid, the value of the dictionary is the value of the values array at that index, which **may or may not be null**. This is similar to StructArray or ListArray, where a null can exist either in the parent array or its child. -- This is an automated message from the Apache Git Service.
