Hi, C++ API doesn't contain the methods to update the baseline. So, in this case, you can use Java API for it:
Add the code that will listen to the EVT_NODE_JOINED event private final IgniteEx ignite; ignite.events().localListen(event -> { DiscoveryEvent e = (DiscoveryEvent)event; final long topVer = e.topologyVersion(); ignite.cluster().setBaselineTopology(topVer); return true; }, EventType.EVT_NODE_JOINED); The whole example you can see here: https://apacheignite.readme.io/docs/baseline-topology#section-triggering-rebalancing-programmatically BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
