             Summary: The RelationalNode.collectNodeStats is only subtracting out the last node
                 Key: TEIID-2475
                 URL: https://issues.jboss.org/browse/TEIID-2475
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.7.5
            Reporter: Debbie Steigner
            Assignee: Steven Hawkins

The "Node Cumulative Next Batch Process Time" Statistic

If you have a look at the explain plan (attached). Following the definition,
the JoinNode Node Cumulative Next Batch Process Time: 565471. So, it is the summation of AccessNode (Node Process Time: 892860) + DependentAccessNode (Node Process Time: 439) + JoinNode (Node Process Time: 2203120). The summation does not agree. 

 The RelationalNode.collectNodeStats looks wrong (it's effectively only subtracting out the last node)
