ES Nest IndexMany批量更新触发Request Entity Too Large

代码：

List<string> uriList=null;
var pool = new StaticConnectionPool(uriList);
var settings = new ConnectionSettings(pool).DefaultIndex(TAGS_INDEX_NAME);
elasticClient = new ElasticClient(settings);

List<T> tagInfos=null;
BulkResponse response = elasticClient.IndexMany(tagInfos, TAGS_INDEX_NAME);

异常：
Invalid NEST response built from a unsuccessful (413) low level
远程服务器返回错误: (413) Request Entity Too Large

原因：
为提高es请求效率，使用分批处理数据，未考虑数据的大小导致

解决方案：
控制文档大小，避免触发 Request Entity Too Large异常
