> I'm not sure if implementing `UnionArray::logical_nulls` is sufficient; as least for dictionary-encoded data it seems to me that `DictionaryArray` does not respect the inner values' logical_nulls (just the raw null buffer if it exists) - I believe that is our interpretation of what the arrow spec says should be done, though as I recall it is somewhat vague on the point (e.g. should the validity bitmap in child dictionary arrays count as a `null`?) -- This is an automated message from the Apache Git Service.
