> HIVE-25256 added support for Iceberg backed tables to support CHANGE COLUMN
> statement. These include type, name and order changes to the schema. Native
> ORC tables only support renames, but with the help of Iceberg as an
> intermediary table format layer, this can be achieved, and works well for
> non-vectorized reads already.
> We should adjust the vectorized read path to support the same.
