> 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.
