the <a href="rollback_and_cache.html" class="wikiLink">previous example</a> directly affects performance: the
less is the depth the less objects will need to be re-read from the database
and the better the performance will be. Ideally we only want to deactivate the
objects that were changed in the rolled-back transaction. This can be done by
providing a special class for db4o configuration. This class should implement
<code>RollbackStrategy/IRollbackStrategy</code> interface and is configured as
part of Transparent Persistence support:</p>

<p>RollbackDeactivateStrategy#rollback method will be

Thus you do not have to worry about deactivate depth anymore - all necessary
deactivation will happen transparently preserving the best performance
