I would guess the `NULL` handling becomes non-trivial, if you start executing queries filtering for the fields containing `NULL` values. What is the results / expected result for: ``` SELECT * FROM word_count WHERE cnt = NULL' SELECT * FROM word_count WHERE cnt is NULL; SELECT * FROM word_count WHERE cnt <> NULL; SELECT * FROM word_count w1, word_count w2 WHERE w1.cnt = w2.cnt; ``` These are things which might return non-excepted results, or handled differently in Iceberg scans and Flink SQL. Ot it could be that simply NULL handling has not been tested/documented yet. -- This is an automated message from the Apache Git Service.
