Steven Hawkins commented on TEIID-2381:
---------------------------------------
#1 is straight-forward.
#2 seems to imply a couple of things. First is that user source hints would no longer
have the ability to affect source queries under a stored / for each row procedure.
I'm not sure how often that application would be used (or is useful) in practice. 2.a.
is also not really feasible unless we add some additional logic to positionally track
subqueries and or move some of the hint application logic to the rewrite phase (as post
rewrite the query structure may have changed altering how subqueries or even views could
be referenced).
Expanded source hint support

Key: TEIID-2381
URL:
https://issues.jboss.org/browse/TEIID-2381
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.4.1
Attachments: HintsExecutionFactory.java, RandomExecutionFactory.java,
RandomNumberStoredProcedureExecution.java, SysviewHintsExecutionTest.java
We currently look at the source hint in only the root user query (not in subqueries nor
the with clause) and only consider it in a very narrow set of circumstances when it's
used in a view.
