I don't see any documentation on scaling GraphEngine.
I'm confused as to how this works. I saw that there is a "distributed" mode. I can add the servers and get them to hook up, but I can't get data to be used in both places.
LocalStorage vs CloudStorage is confusing. It doesn't seem you can query on CloudStorage either (for data that might exist in multiple places).
Do you have any examples of this? I'd be very appreciative.
If you mean LINQ interfaces by "query", then currently there's no built-in support for LINQ over cloud storage. However, it should be easy to write a wrapper handler that broadcasts a query to the cloud, and let each server collect data using LINQ, then aggregated together.
Could you elaborate your scenario? It would be interesting to see how a user would like to query over a distributed cluster.
