             Summary: New subsystem for configuring clustering API implementations
                 Key: WFLY-13007
                 URL: https://issues.redhat.com/browse/WFLY-13007
             Project: WildFly
          Issue Type: Feature Request
          Components: Clustering
    Affects Versions: 19.0.0.Beta1
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro


Currently, WildFly creates services for the following objects for every JGroups channel:
* CommandDispatcherFactory
* Group

... and creates services the following objects for every Infinispan cache:
* SingletonServiceConfiguratorFactory
* ServiceProviderRegistry
* Registry
* Group

Only some of these services are ever started.  If we instead created a separate subsystem that configures these objects, we could significantly reduce the number of services created (but never started) by the jgroups and infinispan subsystems.

This has a number of benefits for users as well:
* Increases overall visibility of the public clustering API
* Simplifies the current mysterious state of service wiring by establishing explicit capability requirements where necessary
