             Summary: More aggressively use enhanced join sorted index to prevent buffering 
                 Key: TEIID-5017
                 URL: https://issues.jboss.org/browse/TEIID-5017
             Project: Teiid
          Issue Type: Enhancement
          Components: Query Engine
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 10.0


In some circumstances the cost of buffering the unsorted side to determine the applicability of the index is greater than simply using the index.  The logic should also use a better estimate of the memory footprint of the index - which is only required to hold the depth of tree in memory at one time.
