StringViewArray --> DictionaryArray<IndexType, LargeUtf8> will copy strings. The current implementation is handled in https://github.com/XiangpengHao/arrow-rs/blob/view-to-dict/arrow-cast/src/cast/dictionary.rs#L259-L283 Which first cast the StringViewArray to StringArray then insert to dictionary one by one. A better approach is probably to directly insert items in StringViewArray to dictionary array. -- This is an automated message from the Apache Git Service.
