> Since the VectorDeserializeRow already calls a setVal(), the copy inside the lower layer is entirely wasteful.
> {code}
> BinarySortableSerDe.deserializeText(
>               inputByteBuffer, columnSortOrderIsDesc[fieldIndex], tempText);
> {code}
> With HIVE-14451, the copies can be avoided for some scenarios and retained for others.
