Jake Mannix commented on GIRAPH-26:
-----------------------------------
Yep, not at all hard to do. I'll see if I can make a quick patch.
> Improve PseudoRandomVertexInputFormat to create a more realistic synthetic
> graph (e.g. power-law distributed vertex-cardinality).

> Key: GIRAPH-26
> URL: https://issues.apache.org/jira/browse/GIRAPH-26
> Project: Giraph
> Issue Type: Test
> Components: benchmark
> Reporter: Jake Mannix
> Priority: Minor
>
> The PageRankBenchmark class, to be a proper benchmark, should run over graphs
> which look more like data seen in the wild, and web link graphs, social
> network graphs, and text corpora (represented as a bipartite graph) all have
> power-law distributions, so benchmarking a synthetic graph which looks more
> like this would be a nice test which would stress cases of uneven
> split-distribution and bottlenecks of subclusters of the graph of heavily
> connected vertices.
