             Summary: Calcite do not trim tables in case of multiple joins
                 Key: IGNITE-24642
                 URL: https://issues.apache.org/jira/browse/IGNITE-24642
             Project: Ignite
          Issue Type: Bug
            Reporter: Maksim Timonin
            Assignee: Maksim Timonin


IgnitePlanner#trimUnusuedFields do not trim fields in case query contains two 
or more joins. 

Comment that describes this logic looks weird, as trims applies on 
PROJECT_PUSH_DOWN to IgniteLogicalTableScan and do not produce new leafs.

Let's remove this condition, as it affects peformance
