["Zoltán Borók-Nagy (Jira)" <ji...@apache.org>]

Zoltán Borók-Nagy commented on IMPALA-11544:
--------------------------------------------

Thanks Manish for raising this.
INSERT-only ACID tables could be migrated in-place as the data files don't have a special schema. Similarly to how legacy tables can be migrated.
For Full ACID tables we need to do the above steps in the description.

> To extend Impala support for Iceberg, we should support reading Hive ACID tables and re-creating them in the iceberg format. The steps would be 
>  # Read ACID table
>  # Create iceberg table in V2 format and parquet file format with a temporary name
>  # Drop ACID table
>  # Rename the iceberg temporary named table to the original table name
>  # Collect stats (optionally)
