    Description

      Give a sync replica cache with 3 nodes
      Introduce a network partition
      Change the cache value
      Fix the network partition
      Check the new cache value

      https://github.com/diegolovison/jgroups-chaos
      mvn test -Dtest=InfinispanPartitionHandlingTest -Dlog4j.configurationFile=log4j2-ispn-conflict-manager.xml

      config:

               cacheConfigurationBuilder.clustering().cacheMode(CacheMode.REPL_SYNC)
            .partitionHandling().mergePolicy(MergePolicy.REMOVE_ALL);

      logs:

      15:44:31,827 INFO  (stateTransferExecutor-thread--p22-t1) [CLUSTER] [Context=org.infinispan.CONFIG] ISPN100002: Starting rebalance with members [Diegos-MacBook-Pro-40446, Diegos-MacBook-Pro-6797, Diegos-MacBook-Pro-52614], phase READ_OLD_WRITE_ALL, topology id 14
15:44:56,725 TRACE (stateTransferExecutor-thread--p22-t1) [StateReceiverImpl] Cache fooCache attempting to receive replicas for segment 83 from [Diegos-MacBook-Pro-40446, Diegos-MacBook-Pro-6797, Diegos-MacBook-Pro-52614] with topologyId=12, timeout=215112

      expected result: for one key, running all cluster in the same machine. I think that we can improve the business rules to avoid taking more than 10 seconds to finish the test.

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) ISPN-11099 Improve Conflict Resolution Performance

          • 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.
