> Currently, we are using utility {{RowData#get(RowData, int, LogicalType)}} and {{ArrayData#get(ArrayData, int, LogicalType)}} to get the field/element objects. However, this is not as efficient as getters of RowData/ArrayData, because this utility involves boxing and unboxing and a big switch condition.
