Sergey Chugunov updated IGNITE-8760: ------------------------------------ Labels: discovery (was: ) > 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 > Components: general > Reporter: Sergey Chugunov > Priority: Major > Labels: discovery > > 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)
