> This JIRA generates the Java code to directly get a value for a primitive 
> type array in ColumnVector without using an iterator for table cache (e.g. 
> dataframe.cache). This JIRA improves runtime performance by eliminating data 
> copy from column-oriented storage to {{InternalRow}} in a 
> {{SpecificColumnarIterator}} iterator for primitive type.
