> There is a ToDo of GenericArrayData class, which is to eliminate boxing/unboxing for a primitive array (described [here|https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/util/GenericArrayData.scala#L31])
> It would be good to prepare GenericArrayData implementation specialized for a primitive array to eliminate boxing/unboxing from the view of runtime memory footprint and performance.
