XSite client failover - ensure TcpTransportFactory.trySwitchCluster thread safety

    XMLWordPrintable

Details

    Description

      When reusing a HotRod client with several threads, site can be accidentally switched multiple times by threads invoking TcpTransportFactory.trySwitchCluster. This occurs when the threads attain 'maxRetries' limit at the same time, each of them being able to invoke TcpTransportFactory..updateServers with different 'clusterAddresses' parameter. This can lead to unpredictable result (e.g. switching back to failed cluster, while the other one (backup) is up and running).

          Task - Represents a small unit of work that is not end-user facing. ISPN-5987 Create concurrent topology switch under failover unit test

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
