the spark and flink's behavior is different. ``` spark: array_contains(array[1, null], null) -> null flink: array_contains(array[1, null], null) -> true so array_remove is also different(the array_remove is supported by me, which aligns with flink). ``` ``` spark: array_remove(array[1, null], null) -> null flink: array_remove(array[1, null], null) -> 1 while array_position is align with spark, i think it is not correct. ``` spark: array_position(array[1, null], null) -> 2 flink: array_position(array[1, null], null) -> 2 and i test on postgre which is also 2 postgre: select array_position(ARRAY[1, null], null); so the semantic should only follow one way to handle null element. so i think it should be changed -- This is an automated message from the Apache Git Service.
