Light-City opened a new issue, #37320:
URL: https://github.com/apache/arrow/issues/37320

   ### Describe the enhancement requested
   
   Ordinary comparison operators yield null (signifying “unknown”), not true or 
false, when either input is null. For example, 7 = NULL yields null, as does 7 
<> NULL. When this behavior is not suitable, use the IS [ NOT ] DISTINCT FROM 
predicates:
   
   a IS DISTINCT FROM b
   a IS NOT DISTINCT FROM b
   
   
   usage:
   
   ```
   select * from test where a is distinct from b;
   ```
   
   or 
   
   
   ```
   select * from test where a is not distinct from b;
   ```

   ### Component(s)
   
   C++
