Thanks Flavio.
Here's my suggestion. If your paths are short and don't vary much, it might
make sense to do this using the DataSet API. The iteration will probably be
too much overhead.
For example, if you want to find the paths for "livesIn.containedIn.name",
then you can create 3 DataSets, one f
In my Implementation every vertex has its own bags of "knowledge" (i.e. it
knows all tuples belonging to it..).
So in Vertex 1 I have a field (an HashMap) containing the following info:
- type=Person
- livesIn=2 (and I know also that 2 is a vertexId)
In Vertex 3 I know:
- type=Place
Hi Flavio,
yes, I think it's possible. I have one question before I try to explain
how:
do you model "Rome", "Berlin", "101.3" etc. in your above example as
separate vertices or as properties of vertices?

Let's say I have some nodes of some type of interest (type1 and type2).
My source data looks like .
For example, I could be interested in sourceNodes having type == Person
to gather the value obtained from the expansion of some paths (for
example livesIn.name and marriedTo.name). Notice that I coul
Is it the same message that you propagate or is it different for each
vertex / neighbor? If you have to store a pair for each
neighbor, then you will quickly run out of memory. If it's the same message
you need to send, or you simply need to add the current vertex Id, then you
can probably get rid
The problem is that my nodes have to gather data coming from some path of
interest along the graph (depending on the type of the node), otherwise
they just have to forward the received message adding their id to the
message path (more or less). It's like a postal tracking system.
The problem is th
Hi Flavio!
Are you talking about vertex-centric iterations in gelly?
If yes, you can send messages to a particular vertex with
"sendMessageTo(vertexId, msg)" and
to all neighbors with "sendMessageToAllNeighbors(msg)". These methods are
available inside the MessagingFunction.

Hi to all,
is there a way in gelly to forward received messages (and modify their
content before sending)?
Best,
Flavio
