             Summary: Change the applicability of subqueryUnnestDefault
                 Key: TEIID-2149
                 URL: https://issues.jboss.org/browse/TEIID-2149
             Project: Teiid
          Issue Type: Enhancement
          Components: Query Engine
    Affects Versions: 8.2
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.2

subqueryUnnestDefault should only apply during rewrite, since it is run without cost analysis.

However the unnest logic should always run in the optimizer and if necessary the user can use the NO_UNNEST hint to keep the subquery inline.
