Stream vertex edges off of disk -- (HDFS solution? -- ImmutableBytes solution?)

[okram]

solve the super node problem for a vertex (can't always assume we can hold in memory)

So perhaps a memory mapped FaunusVertex implementation?

This could kick in once the number of edges reach a large size.

If you could get the FaunusEdge lists backed by a HDFS inputstream, that would be cool.

I had a good look at this - but am getting cold feet.
The idea was to stash the FaunusEdges in MapDB and use PantomReferences to detect when the store needed to be updated. For this to work the FaunusEdge needs to be separated in to a wrapper and data objects and the edge lists replaced by a cache implementation.
However, the underlying Faunus code is complex and I am worried that I may find that this doesn't work after a lot of effort. Sorry, I'm not confident at taking this to its conclusion right now. Willing to discuss further though.
