> Current {{ColumnVector}} accepts only primitive-type Java array as an input for array. It is good to keep data from Parquet.
> On the other hand, in Spark internal, {{UnsafeArrayData}} is frequently used to represent array, map, and struct. To keep these data, this JIRA entry enhances {{ColumnVector}} to keep UnsafeArrayData.
