Hello,
In Giraph is it possible to have different node types in a graph and have a
Map/Reduce only iterate over nodes of this type and their direct successors?
If it sounds a bit cryptic here is something more about our use-case:
We have different HBase tables which we want to pseudo-join in
Giraph does not support multipartite graph in a natural way. But you can
try to model your different sets through the vertexvalue. You can then
propagate it (by composing with the ID?) to the neighbors, and obtain your
join.

I agree, something like this is possible using the vertex value. In giraph,
we now have native support for multigraphs, but before we had that support,
I described a kind of cheat to process multigraphs. You could use a
variation of that same cheat (its on the site confluence wiki) to do what
One more general point would be whether giraph is a better tool for your
problem. From my understanding, map reduce is probably the way to go.
