I still think we need to think about how to
handle distributed data stores so they appear as a single data store to the

The graph event handler contract does not work outside a single JVM.
For example, the event is dispatched and processed before the Graph.add
returns. Bad threading contract. Not viable in a distributed situation
(too many events, wrong timing) even without Cassandras eventual
consistency.
RDF Delta is an approach at addressing this
* Larger granularity (the transaction)
* Responsibility moves to the watchers who controls when change handling
happens
How are you dealing with the eventual consistency generally?
