ZookeeperCacheNodeGroup

class ZookeeperCacheNodeGroup extends Group[CacheNode] with ZookeeperStateMonitor

Zookeeper based cache node group with a serverset as the underlying pool. It will monitor the underlying serverset changes and report the detected underlying pool size. It will monitor the serverset parent node for cache pool config data, cache node group update will be triggered whenever cache config data change event happens.
