[teiid-issues] [JBoss JIRA] (TEIID-5017) More aggressively use enhanced join sorted index to prevent buffering

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, 9.3.3 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.
