             Summary: ClusterTopologyManagerImpl should only use non-blocking RPCs
                 Key: ISPN-8955
                 URL: https://issues.jboss.org/browse/ISPN-8955
             Project: Infinispan
          Issue Type: Task
          Components: Core
    Affects Versions: 9.2.0.Final
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 9.3.0.Final


{{ClusterTopologyManagerImpl}} still uses some blocking RPCs, particularly when a node becomes coordinator or after a merge. It should use non-blocking RPCs instead.

It could also use non-blocking RPCs instead of fire-and-forget messages for things like topology updates, which would allow delivering topology updates in the same order on all the nodes instead of having regular nodes make to with missing topology updates (when the coordinator doesn't change).
