> In case an iceberg table has gone through partition evolution, we don't allow
> an IOW operation on it.
> But if it is empty, we can allow an IOW since there ain't any data which can
> get messed by overwrite.
> This helps to compact data, & merge the delete files into data file
> via
> Truncate -> IOW with Snapshot ID before Truncate.
> Same flow is used by Impala for compacting Iceberg tables.
