ElasticSearch.NET连接/客户端管理生命周期

当我使用ElasticSearch.NET建立与ElasticSearch集群的连接时,我使用的代码块如下:

var uris = settingsProvider.ElasticSearchUri.Split(';').Select(x => new Uri(x));
var sniffingConnectionPool = new SniffingConnectionPool(uris);
var connectionConfiguration =
    new ConnectionConfiguration(sniffingConnectionPool)
        .SniffOnConnectionFault()
        .SniffOnStartup();
var client = new ElasticsearchClient(settings: connectionConfiguration);

难道建议我memoize的/让静态/做一个单包装的ElasticsearchClient,对ConnectionConfiguration,或者SniffingConnectionPool使他们不必每次都让我搜到重建？
