Hi Yutao, no, the Akka Cluster gossip does not perform indirect probing. Since Akka messaging is direct between nodes (in most cases), indirect reachability (with direct non-reachability) would still mean messages to Mj would be lost, even if we could route messages "around there via Mk". Such routing would complicate things a lot and also go against the let-it-crash motto of Akka / Erlang.
If you have a specific reason you're asking about this let us know. The question seems a bit without context. Note that Akka Cluster has been shown to scale to thousands of nodes and remain stable: https://cloudplatform.googleblog.com/2014/01/large-akka-cluster-on-google-compute.html (And that's 2 years ago, before we did a number of improvements in the Cluster and Remoting). -- Konrad `ktoso` Malawski Akka <http://akka.io> @ Lightbend <http://lightbend.com> On 27 July 2016 at 10:51:49, Yutao Shuai (szqs...@gmail.com) wrote: Indirect probe described as below.

Each of these k targets then sends a *ping* toMj on behalf of Mi and on receiving an *ack*notifies Mi. If, for some reason, none of these processes receive an *ack*, Mi declares Mj as failed and hands off the update to the dissemination component. <http://prakhar.me/images/swim.png> Detail is in here <http://prakhar.me/articles/swim/> -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
