Hi Yong, Perhaps designers then, at least thats what I think the posters are referring to and certainly what I am. The application would lend itself better to RAC (scale better/well) if its data is logically partitioned and could make good make use of services. By partitioning, I don't mean at the table level here, but at the level Gints Plivna was referring to. But for this to happen, its the developers/designers that need to be thinking RAC.
