Hi all,

a plan to use Giraph for a use case where nodes send messages depending on some 
global distribution of a value. For instance, nodes have a numeric value. Thus 
there is a global distribution of that value. Now I want all nodes to take an 
action, i.e., send messages, that have a value in say the top 1% of all values.
How could I do this?
Thinking in Hadoop MapReduce I'd use the distributed cache in order to maintain 
a fingerprint of the global distribution.
Would this work in giraph too?

Thanks and BR!
christoph
