[Wsf-general] data services and resources

[Paul Fremantle]

I was at a very interesting talk by Werner Vogels from Amazon here at QCon.

He was describing how Amazon is building a lightweight data service 
called Dynamo to handle much of the "shopping cart" data they need.

Basically, the tradition RDBMS is not what they need, because they 
simply put XML documents into the store with a key and get them out 
again. So Dynamo is a very high performance, highly-available, 
clustered, persistent hashtable. It deliberately trades consistency for 
availability.

He made the point that they don't need any schema (its key->blob), query 
(they don't even need iterators), consistency etc.

So... is there a layering of this API that makes it simple to do XML 
storage without defining a schema? For example mapping xs:any?
