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)
