[JBoss JIRA] (ISPN-3947) HotRod client keep trying recover connections to a failed cluster

by Wolf-Dieter Fink (JIRA)

Wolf-Dieter Fink created ISPN-3947: -------------------------------------- Summary: HotRod client keep trying recover connections to a failed cluster Key: ISPN-3947 URL: https://issues.jboss.org/browse/ISPN-3947 Project: Infinispan Issue Type: Feature Request Components: Remote Protocols Affects Versions: 6.0.1.Final, 7.0.0.Alpha1 Reporter: Wolf-Dieter Fink Assignee: Galder Zamarreño If an infinispan-server cluster is not longer reachable for some reason, i.e. network disconnect, the hot-rod client try to re-establish the lost connections. The client library will retry this by a fixed calculation based on the max numbers of connections from the pool or 10 multiplied with the number of available servers. This can lead in a very long time until the application can continue and react as it will wait for the read- or connect-timeout for each try. To improve this behaviour there should be a configurable limit of retries per server and/or a timeout in total. This will give the application the chance to handle a remote-cache failure and reply to the user instead of hanging for minutes (with the default settings) -- This message is automatically generated by JIRA.

[JBoss JIRA] (ISPN-3876) TcpTransportFactory stores failed SocketAddress in RequestBalancingStrategy

by Patrick Seeber (JIRA)

[ https://issues.jboss.org/browse/ISPN-3876?page=com.atlassian.jira.plugin.... ] Patrick Seeber edited comment on ISPN-3876 at 1/28/14 9:15 AM: --------------------------------------------------------------- Thank you for your answer! Indeed it is not self healing and we believe we found the problem. The scenario is: 1. Start 2 servers in replicated mode 2. Start a Client which connects to both servers correctly 3. Shutdown Server 1 during maintenance 4. Perform a client operation, the new topology is now commited to the client, the balancer now knows only Server 2 5. Bring up server 1 again and shutdown server 2 during maintenance 6. Bring up server 2 again Now the client is broken since the last server he knows (Server 2) wont send any topology changes to the client if the client performs operations now. There is no chance for the client balancer to receive both servers again, which is problematic if the communication to the only known server fails now. To fix this, we would be forced to perform a client operation between step 5 and 6, but we have 10 clients and we do not want to trigger a getCache 10 times each time we shutdown a server. Is there any way to ping the servers from the client in a specific interval or to directly inform the client if the topology changes? was (Author: patrick_seeber): Thank you for your answer!
