> I have a partitioned table which has 1 backup, the *queryParallelism* is set to 4.
> The table primary key is column "ID", 
> If I do this query:
>         select count( * ) from my_table where ID = 1000;
> It will return 4 rows:
>         1
>          0
>          0
>          0
>  
> If I query by other not primary-key columns of this table, the result is good, like:
>         select count( *) from my_table where name = 'abcd'
> result is:
>         0
