Can we keep the rest client alive through out the application life cycle. or do we need to close the client after each request.

final RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200, "http")).build();

public void onSuccess(Response response) {  
try {  
System.out.println(EntityUtils.toString(response.getEntity()));  
} catch (ParseException e1) {  
// TODO Auto-generated catch block  
e1.printStackTrace();  
} catch (IOException e1) {  
// TODO Auto-generated catch block  
e1.printStackTrace();  
}  
try {  
restClient.close(); **-- Does this need to happen**  
} catch (IOException e) {  
// TODO Auto-generated catch block  
e.printStackTrace();  
}

```
		}
```

You can reuse the same `RestClient` instance through the entire lifetime of your application.

Thank you. That is what the documentation says just wanted to hear from someone else too.
