   > A check in hash_aggregate if the null count in all group columns is 0
   
   What is `all group columns` referring to here please? 
   
   Perhaps is this the same as checking that for each `array` that appears on 
https://github.com/apache/arrow-datafusion/blob/master/datafusion/src/physical_plan/hash_aggregate.rs#L371
 we check that `array.null_count() == 0`
