I would bet the cluster creation is only done at class creation. Once the 
clusters are made, it wouldn't matter what the hardware changes to.

As I see it, the whole idea of the additional cluster creation is to help 
parallelism i.e. concurrent execution and lesser about data locality 
control, whereas, it looks like the data locality can always be done later 
in a distributed setup too. So, I see no big deal. 

Sfinx, you keep mentioning clustering of classes, but I think the term 
"cluster" in ODB terms is slightly different. To me, from a sharding system 
standpoint, the ODB "cluster" should actually be called a "chunk". Where, 
all the chunks of a class make up the whole cluster for that class. I guess 
"cluster" is sexier than "chunk". LOL!
