如何使用 JAVA 高级别 Z50780F47F6839D047D60BC453

Question

It will be helpful if someone can point me to a way to execute Point In Time API request, which is newly introduced in Elasticsearch 7.10.1, from JAVA using REST high-level client or any other way in JAVA. （Transport 客户端除外，因为它很快就会被弃用）

Answer 1

当高级 rest 客户端没有任何 api 的包装器时，低级 rest 客户端来救援。 您可以通过高级客户端使用低级客户端，如下所示：

String endPoint = "my-index-000001/_pit";
Request request = new Request("POST", endPoint);
request.addParameter("keep_alive", "1m");
Response response = highLevelClient.getLowLevelClient().performRequest(request);

然后使用response object 提取出相关信息。
