   Regarding my concern about memory usage, I was talking about `Digest` and the extra list used to store `items` which is kind of redundant with the `RelNode` itself. An alternative could have to replace the list of extra fields with an `Iterable` and call it each time items need to be collected? It could also possibly eliminate the creation of an array to do a comparison between objects...
