Nick, Here are some comments on your questions:
1. Heartbeat is always sent to the next node in the ring. That's the whole point of the ring architecture vs. peer-to-peer. 2. That's not possible, because each discovery message is sent across the ring, and the ordering of those messages is guaranteed to be consistent across nodes. 3. In short, when one of the node in unhealthy, healthy node behind detects it (can't send heartbeat) and then tries to connect to node that follows the unhealthy one. If successful, that effectively creates a new ring and new topology without the unhealthy node. In split-brain scenario you will have two independent clusters (two segments). -Val -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
