    Switch JOINT prefetches to generate OUTER Joins.
    -------------------------------------------------

                     Key: CAY-1128
                     URL: https://issues.apache.org/cayenne/browse/CAY-1128
                 Project: Cayenne
              Issue Type: Improvement
              Components: Cayenne Core Library
        Affects Versions: 3.0
                Reporter: Andrus Adamchik
                Assignee: Andrus Adamchik
                 Fix For: 3.0

    Switch JOINT prefetches to OUTER Joins. This is related to CAY-1025. JOINT_PREFETCH_SEMANTICS using inner joins makes little sense and is a complete hack. Changing it to use OUTER joins suddenly makes it usable (and in fact even more robust than DISJOINT prefetches - see the problem described in CAY-1025).

    Needed code was committed as a part of CAY-1025 work, so here we'll need to update the docs and the UPGRADE-NOTES.txt.
