    Need ability to break data maps into multiple XML files (on entity by entity basis)?

                     URL: https://issues.apache.org/cayenne/browse/CAY-969
                 Project: Cayenne
              Issue Type: New Feature

        Affects Versions: UNDEFINED FUTURE

    Problem: suppose it takes 5K per small table or twice that (10K) for a bigger table definition in the data map file. When the table count shoots up into several hundreds, we are looking into datamap XML files several megs big. Now suppose you store the Cayenne xmls under a version control and use it to track the changes. The size along with natural problems of XML versioning makes it very difficult to understand any arbitrary non-trivial change in the past. If there was a chance to break those files on entity-by-entity basis, that would make change tracking easy.
