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. This change makes vectorized orc reads relies on Iceberg on finding out about column renames and reorders, so that the low level ORC vectorized reader can be appropriately configured. -- This is an automated message from the Apache Git Service.
