https://issues.jboss.org/browse/TEIID-2149?page=com.atlassian.jira.plugin...
]
Steven Hawkins resolved TEIID-2149.
-----------------------------------
Resolution: Done
Changed the default to apply to the rewriter, added a release note, and updated the docs.
Also added an Options class that should be used to rather than direct system property
manipulation.
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.
