ElasticSearch Index API SLOW

Question

public static void main(String[] args) {

        Node node = nodeBuilder().clusterName("somethingstupid").client(true).node();
        Client client = node.client();

            String json = 
                    "{\"user\":\"kimchy\"," +
                    "\"postDate\":\"2013-01-30\"," +
                    "\"message\":\"trying out Elastic Search\"}";              

            IndexResponse response = client.prepareIndex("testindex", "article")
                    .setSource(json)
                    .execute()
                    .actionGet();

    }

为什么在eclipse中需要9-12秒才能将其编入索引？

Centosx64 6.4，ES 0.90.7,2GB内存，没有其他运行，Sysmon显示使用3％cpu和800MB RAM at PEAK（DURING INDEX）。

示例线程：

public class TestPostMethod2 implements Runnable{
    public static Node node = nodeBuilder().clusterName("somethingstupid").client(true).node();
    public static Client client = node.client();

    public void run() {
        String json = 
                "{\"user\":\"kimchY\"," +
                "\"postDate\":\"2016-01-30\"," +
                "\"message\":\"trying out Elastic Search\"}";              

        IndexResponse response = client.prepareIndex("testindex", "article")
                .setSource(json)
                .execute()
                .actionGet();
    }

    public static void main(String[] args) throws IOException {

        (new Thread(new TestPostMethod2())).start();
    }

}

创建完整的elasticsearch节点需要时间。 在实际项目中，一旦获得客户端，您只需在所有线程中共享它。

索引部分应该很快。

如果您想索引更多文档，请考虑使用批量API。
