Alessandro Presta commented on GIRAPH-616:
------------------------------------------
Seems like a good improvement. I'm not up to speed on the recent changes in
Vertex so I can't comment in detail.
> Decouple vertices and edges in DiskBackedPartitionStore and avoid writing
> back edges when the algorithm does not change topology.

> Many algorithms work on a static graph. In these cases, when running
> out-of-core graph we end up writing back the edges that have not changed
> since we read them. By decoupling vertices and edges, we can write back only
> the freshly computed vertex values.
