Same routing behavior on different nodes/routers

Question

I know, that if I use a consistent hashing group router, it will always rout to the same registered routees.

So I wrote my application, with a few routees on there own routee-nodes and a public-node with a router, which is reachable by the client.

If the client sends a message it is routed as it should be and it works fine.
Now what I want to do is, add more public-nodes with thier own router that provides the same sending/routing behavior as every other public-node.

What I mean is, that it should not matter if a client sends message XYZ to public-node A, B or C. It should always go to the same routee-node.

At first I thought that akka may provides this behavior by default, because:

1. I used a group and not a pool router, so everyone knows the same routees
2. I leared that cluster nodes could be ordered

So I assumed that the routees list is ordered and the different routers map the same keys to the same routees. But testing showed me that I was wrong.

So, is there way in akka to achieve this behavior? Thanks.

Answer 1

As I expected, this behavior shoud be the standart for consistent hashing group routers and it is a bug in the akka-cluster package (current version 2.3.0-RC1)

See this tickt and this google-group post for more details.
