             Summary: Inconsistent sql result for "select min/max" on single 
and multiple nodes with nulls
                 Key: IGNITE-15615
                 URL: https://issues.apache.org/jira/browse/IGNITE-15615
             Project: Ignite
          Issue Type: New Feature
            Reporter: Maksim Timonin


select min(price) from Price.
 
Put data to Price.price: (null, null, 10, 30)
 
1. Start on single node  - it returns null
2. Start on multiple nodes - it returns 10

Signle node query doesn't start reduce phase, that filter null values in H2. So 
result is consistent.
