All Superinterfaces:

All Known Implementing Classes:

```
public interface Client
extends ElasticsearchClient, Releasable
```
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.
