             Summary: Split schema synchronization code in a separate module 
                 Key: CAY-2116
                 URL: https://issues.apache.org/jira/browse/CAY-2116
             Project: Cayenne
          Issue Type: Task
            Reporter: Andrus Adamchik
            Assignee: Andrus Adamchik


There are no real reasons why classes like DbLoader , merge package, and DbGenerator are a part of Cayenne core. There is a technical reason - these classes depend on customizations coming from DbAdapter. 

We need to split them to a separate module (cayenne-dbsync), preserving all adapter customizations (specifically for MergerFactory). I was able to do that by implementing a special explicit "PerAdapterProvider" class that uses adapter class name as a key to DI-bound map of factory implementations.

THIS IS A BREAKING CHANGE

Many classes are moved from cayenne-server, and placed in a different package namespace (org.apache.cayenne.dbsync and subpackages).
