Elasticsearch - node client does not connect to cluster

Elastic Stack Elasticsearch
10

Hi,

You are correct that you should not create a new client for every connection, but rather re-use a single client.

Note that all the client methods support being called asynchronously by passing in a response listener, or returning a future. Which is to say, if you are submitting several queries at once, you need not wait for each to return before submitting the next.

I am newbie in elastic and I don't understand how should I work with transport client connections. Should I use singleton for Client, something like

class ElasticClientManager {
private static Client client;

public static Client getClient(){
if (client==null) {
Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", "elasticsearch")
.put("client.transport.sniff", true).build();

   client = new TransportClient(settings)
        .addTransportAddress(new InetSocketTransportAddress("localhost",9300));
}

return client;
}
}

By other words - I create one client and keep the reference in it in singleton. Every time I need to query elastic I do

Client client = ElasticClientManager.getClient();
GetResponse getResponse = client.prepareGet(....).execute().actionGet();

Is such approach right?
