Summary: TcpDiscoverySpi: validation of discovery message path on each node Key: IGNITE-8760 URL: https://issues.apache.org/jira/browse/IGNITE-8760 Project: Ignite Issue Type: Improvement Reporter: Sergey Chugunov As each discovery message goes across the ring it can record all nodes it was handled on. It gives discovery protocol an opportunity to set up a constant monitoring of cluster topology: each node on receiving discovery message will compare path recorded by the message and its local picture of current topology. On detecting any discrepancy node may at least print warning or take other actions. Path recording may be expensive in terms of network traffic so it is better to add this logic to specific types of discovery messages: all topology changing messages and (may be) heartbeats. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
