-------------------------------------
Summary: Enhanced sort join produces duplicate results
Key: TEIID-2942
URL: https://issues.jboss.org/browse/TEIID-2942
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 8.4
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Critical
Fix For: 8.7.1, 8.8
In a plan where an enhanced sort join chooses to create an index on a child that should be
SORT_DISTINCT, the distinct processing does not occur.
For example this would occur with a query such as:
select a.e1, b.e2 from pm1.g1 as a, (select e1, e2 from pm2.g2 union select e1, e2 from
pm2.g2) as b where a.e1 = b.e1
where the source does not support union.
