HotRod Client - TcpTransportFactory - update topology issue with multiple caches -------------------------------------------------------------------------------- Key: ISPN-6771 URL: https://issues.jboss.org/browse/ISPN-6771 Project: Infinispan Issue Type: Bug Components: Remote Protocols Affects Versions: 9.0.0.Alpha2, 8.2.2.Final Environment: Infinispan server 8.2.2.Final Hot rod client (Java) : 8.2.2.Final Reporter: Jean-Francois LARTAUD Assignee: Gustavo Fernandes After debugging : In TcpTransportFactory, the topologyInfo is global (whatever the number of caches), the balancing strategies are defined by cache. * For the 1st cache, the servers list is updated (org.infinispan.client.hotrod.impl.transport.tcp.TcpTransportFactory#updateServers(java.util.Collection<java.net.SocketAddress>, byte[], boolean), the topologyInfo is updated. ** The new servers list is returned only if servers have been added. ** As this list is not empty, the balancy strategy for the first cache is updated. * For the other caches, the server list is updated by calling the same "updateServers" method, the "updateTopologyInfo" method is called ** But as the topologyInfo has been already updated for the 1st cache, it returns "Collections.emptyList();" ** The associated balancing strategies are not updated. {code} public void updateServers(Collection<SocketAddress> newServers, byte[] cacheName, boolean quiet) { synchronized (lock) { Collection<SocketAddress> servers = updateTopologyInfo(newServers, quiet); if (!servers.isEmpty()) { FailoverRequestBalancingStrategy balancer = getOrCreateIfAbsentBalancer(cacheName); balancer.setServers(servers); } } } {code}
