public interface Client
A client provides a one stop interface for performing actions/operations against the cluster.
All operations performed are asynchronous by nature. Each action/operation has two flavors, the first
simply returns an ActionFuture
, while the second accepts an
ActionListener
.
A client can either be retrieved from a Node
started, or connected remotely
to one or more nodes using TransportClient
.
Node.client()
