   In Flink SQL, data is transferred from one operator to another as a Chanlog 
Stream. Changelog Stream can be translated as either a table or a Stream.
   
   Iceberg should be more like a Dynamic Table. In our case above, I think it 
should materialize changes rather than store changes in the table as they were.
   
   > Do you mean that the new sink doesn't pass the RowKind and you only get in 
inserted rows?
   
   Sink will not just receive Inserted Rows. With Flink CDC, it can receive 
change log normally.
