multigraph support in giraph

Hi All,
        Does Giraph supports Multigraph. I am planning to load a Bipartite
graph data in Giraph. Is it possible.

I saw this issue is still opened,

https://issues.apache.org/jira/browse/GIRAPH-141

Does this patch got accepted and is it available in 0.1 release..

Some one reply.

*Cheers,*
Sri

Multigraph isn't supported directly by the infrastructure, but can be 
implemented by using an appropriate edge type to support the multiple 
edges of your graph.

yes, i usually upload a patch with the additional documentation. The
commit then requires also the generation of the new documentation with
update of the site via rsync. There's a page describing the command on
the wiki.

I'd be happy to!

Add it to the site docs in the src and upload a patch? its the first time
I've done this sort of alteration.

Do you want to do this Eli?  I think it's a good idea.

Nicely put. We should do small write up on the site to illustrate this
question to new users, it comes up a lot. The vertex model we currently
support has its down sides, but its much more flexible than I for one first
realized when I encountered it.

Re: multigraph support in giraph

i think there's a misunderstanding in the definition of multi-graph,
between a graph with multiple edges between a pair of vertices
(correct definition), and multiple types of vertices (wrong
definition). As Avery mentioned, the first can be solved by defining a
special Edge type while the second can be implemented by a parameter
to the constructor and a compute method with a switch statement on the
parameter value.

Can you clarify what kind of data you have? A bipartite graph is a graph
with no odd cycles, and that has nothing to do with multigraphs.
