Finer Grain Control on settings
-------------------------------

         Key: IBATIS-161
         URL: http://issues.apache.org/jira/browse/IBATIS-161
     Project: iBatis for Java
        Type: Improvement
  Components: SQL Maps  
    Versions: 2.1.2    
    Reporter: Stephane Bailliez
    Priority: Minor


Following my post in the dev list.

It would probably be interesting to have fine-grained control over the lazy-loading.
For instance, having a per-statement lazy-loading flag where dependent requests (like in the case of n+1 selects) would inherit this flag.

I came over it after discovering that cglib-enhanced classes are not serializable, which make sense due to lazy-loading.

You could need it for the following case:

You may know, that your relationships are not in the form 1:bazillion but more like 1:4 (replace 4 by your favorite 'less than 10' number) with very lightweights objects , thus the need to potentially be able to disable cglib enhanced relations.

To workaround this, you can:

1) disable application-wide lazy loading via <settings/> (big side-effect)
2) implements your own serialization mechanism by basically cloning the relations. (code clutter)
