Subject [jira] [Commented] (GIRAPH-27) Mutable static global state in Vertex.java should be refactored
Date Fri, 09 Sep 2011 00:36:09 GMT

Jake Mannix commented on GIRAPH-27:
-----------------------------------

Can anyone try to run something like the SimplePageRank stuff on some real data on a real
cluster, to make sure that cross-JVM boundaries are properly working?  Hard to test the effect
of this kind of change on that kind of thing in unit tests alone...

> Vertex.java has a bunch of static methods for getting/setting global graph state (total
number of vertices, edges, a reference to the GraphMapper, etc).  Refactoring this into a
GraphState object, which every Vertex can hold onto a reference to (yes, a tiny bit more memory
per Vertex, but in comparison to what's already in there...)
