------------------------------------

             Summary: Don't use DISTINCT for joins on to-one related tables
                 Key: CAY-2683
                 URL: https://issues.apache.org/jira/browse/CAY-2683
             Project: Cayenne
          Issue Type: Improvement
          Components: Core Library
    Affects Versions: 4.2.M1, 4.2.M2
            Reporter: Nikita Timofeev
            Assignee: Nikita Timofeev
             Fix For: 4.2.M3


New {{SelectTranslator}} introduced in CAY-2465 uses {{DISTINCT}} by default 
for all queries that have at least one join. This could lead to some 
performance issues. Moreover, this logic differs from the old translator.
