    This shouldn't be a problem. Cayenne caches blocks of primary keys by default (I think 20 at a time -- this would be a cache of 20 for each table at a time). This will reduce the load on the DB when doing inserts. You can set this parameter yourself, if needed. See the documentation for org.objectstyle.cayenne.dba.JdbcPkGenerator.setPkCacheSize(int size) for more information.

    Note that your actual implementation is probably one of the subclasses.

    Hi,

    we are planning a Swing GUI for rich clients.

    There is one thing I'm not sure:
    Does the PK Generation a correct job,
    when there are many clients active?

    Thanx
