Hi there
In my project I have to implement a routing system with good performance;
at the beginning this system should be able in giving routes information
only for one italian region (Lombardia) but it could be used for the whole
Italy (or world)
Let's stop to the Lombardia for now. By
For such a small graph, using a single machine graph processing system
makes more sense imho. Should be faster and easier to program. Google for
cassovary.

hi Sebastian
thnx for the answer
I was giving a look to cassovary, but I'm losing hot to integrate it with
neo4j and/or hor to calculate paths with it.Do you have any tips?

It looks like you're expecting to use Giraph in an online fashion, such as
you would use a database to answer queries within milliseconds or seconds.
Giraph is an offline batch processing system.

hi Claudio
so, if I understood correctly, it has no sense to use Giraph for shortest
path calculation in my scenario
Am I right?

Hi Angelo,
It very much depends on your use case. Do you want to precompute paths
offline in batch or are you looking for a system that answers online?
Giraph has been built for the first scenario.

Nope, you can think about Giraph as MapReduce for graphs. Probably neo4j
C is the way to go for you.

Hi Giraphers..
Suppose in single source shortest path sample example data given below,
[1,0[[2,*10*],[3,*20*]]]
In Giraph, can we udate the edge weight *10* and *20* during our compute
function??
Seeking your ideas..
Thanks
