Hi Stanislav, Yes persistence is enabled and version is 2.4.
Have tried to update topology after one node restart with below code from client: Collection<ClusterNode> nodes = ignite.cluster().forServers.nodes(); ignite.cluster().setBaselineTopology(nodes); And after that I still have all primary entries stored on one node and backup entried on the one which I restarted. Maybe that method of topology update is incomplete? Thanks in advance for your reply.
