> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 2.8.1
> Reporter: Isaac Zhu
> Assignee: Yury Gerzhedovich
> Priority: Major
>
> 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
