Examples of CacheTopology

org.infinispan.topology.CacheTopology
The status of a cache from a distribution/state transfer point of view.
The pending CH can be {@code null} if we don't have a state transfer in progress.
The {@code topologyId} is incremented every time the topology changes (i.e. state transferstarts or ends). It is not modified when the consistent hashes are updated without requiring state transfer (e.g. when a member leaves). @author Dan Berindei @since 5.2
