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: 6.0.0 Reporter: Debbie Steigner Assignee: Steven Hawkins Fix For: 8.4.1, 8.5 Attachments: Query_Plan.txt 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)
