Reading the CDO Performances wiki, regarding the model definition, I cannot test what it is mentioned : https://wiki.eclipse.org/CDO/Tweaking_Performance#Defining_a_Model
Indeed, in this section, one hint is to set to false the unique property for containment reference, in the Ecore model, if we know 'a priori' that our algorithm does never violate a uniqueness constraint.
I tried to do so for tests purpose, but I cannot validate my EMF model.
I get this validation error : A containment or bidirectional reference must be unique if its upper bound is different from 1
I can only switch to false for non-containment reference and for many-valued attribute based on EDataType.
Does anyone know if it is a mistake in the CDO wiki or a change since the page was written ?
If CDO do not use EMF proxies, could you please detail why switching resolveProxies to false can help performances since it is not used in CDO implementation ?
Thanks for your help,
