Ádám Szita updated HIVE-25360:
------------------------------
Description:
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.
> Iceberg vectorized ORC reads don't support column reordering
