   ### Query engine
   
   Flink 1.17.1
   
   ### Question
   
   According to https://iceberg.apache.org/docs/latest/flink/#flink-to-iceberg, 
Iceberg does not handle Flink's `null`. Can you please describe the cases where 
the `null` support is missing or limited?
   
   I tried a very basic example - inserted a row without specifying values for 
all columns and it worked:
   
   ```
   CREATE TABLE word_count (
       word STRING,
       cnt BIGINT,
       PRIMARY KEY(`word`) NOT ENFORCED
   ) PARTITIONED BY (word) WITH (
       'format-version'='2', 
       'write.upsert.enabled'='true'
   );
   
   INSERT INTO word_count (word) VALUES ('zz');
   
   SELECT * FROM word_count WHERE word = 'zz';
   +----+--------------------------------+----------------------+
   | op |                           word |                  cnt |
   +----+--------------------------------+----------------------+
   | +I |                             zz |               <NULL> |
   +----+--------------------------------+----------------------+
   Received a total of 1 row
   ```
