public class JdbcResourceSynchronizer
extends CronResourceSynchronizer<JdbcResource,JdbcResourceNode>

Performs synchronization using JDBC. Every table must have a primary key. Also, assumes that updating a non-primary key value will have no affect on other data. Primary keys themselves are never updated, rows will be deleted and then inserted in this case. For table dependencies, only uses primary keys and foreign keys that go to primary keys. There must not be any cycle in the dependency graph.
