Summary: CacheRegistry and CacheServiceProviderRegistry cache mapping is suboptimal

CacheRegistry and CacheServiceProviderRegistry cache mapping is
suboptimal
--------------------------------------------------------------------------
Key: WFLY-9521
URL:
https://issues.jboss.org/browse/WFLY-9521
Project: WildFly
Issue Type: Bug
Components: Clustering
Affects Versions: 11.0.0.Final
Reporter: Paul Ferraro
Assignee: Paul Ferraro
Both the org.wildfly.clustering.registry.Registry and
org.wildfly.clustering.provider.ServiceProviderRegistry currently store references to a
Node object in their respective caches. The AddressableNode implementation currently
serializes:
* org.jgroups.Address
* The logical name (typically a host name)
* The socket binding address/port of its transport
This is overkill. The Node should only need to serialize enough information to
reconstruct itself using a NodeFactory<Address>, which should only include:
* its Address
* something to minimally identify the NodeFactory<Address>, with which to use to
reconstruct the Node, e.g. a group name
Unfortunately, getting a reference to the NodeFactory during deserialization isn't
trivial, as these are on-demand services.
Another approach, is to avoid referencing the Node in cache keys/values altogether.
Currently, Registry<K, V> uses a Cache<Node, Map.Entry<K, V>> and
ServiceProviderRegistry<K> uses a Cache<K, Set<Node>>. In both cases, we
can replace Node with Address, and thus avoid unnecessary marshalling of the logical name
and physical address of a member.
