Maja Kabiljo commented on GIRAPH-616:
-------------------------------------
Awesome results!
If you were to try with bigger graph, maybe the variance would be smaller? Do
you know where the variance comes from?
The patch looks good to me, let's have giraph-613 figured out first, and we can
commit this.
> 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.
