ElasticSearch設置索引全局默認分片

設置全局分片數量：
put http://196.168.137.100:19085/_template/template_http_request_record
{
“index_patterns”: ["*"],
“settings”: {
“number_of_shards”: 5,
“number_of_replicas”: 1
}
}
指定創建索引時的分片數量：
put http://196.168.137.100:19085/<索引名稱>
{
“settings”: {
“number_of_shards”: 12,
“number_of_replicas”: 1
}
}
client7.4.0創建索引時，指定主副分片

<dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>7.4.0</version>
        </dependency>
        <dependency>

            <version>7.4.0</version>
        </dependency>

代碼：

//創建索引
            CreateIndexRequest createIndexRequest = new CreateIndexRequest(“index”);
            //設置分片
            createIndexRequest.settings(
                    Settings.builder().put("index.number_of_shards", 5)
                            .put("index.number_of_replicas", 3));
            //同步響應
            CreateIndexResponse createIndexResponse = client.indices().create(createIndexRequest, RequestOptions.DEFAULT);
            boolean acknowledged = createIndexResponse.isAcknowledged();
            boolean shardsAcknowledged = createIndexResponse.isShardsAcknowledged();
            if (acknowledged && shardsAcknowledged) {
                System.out.println(indexName + "索引創建成功");
            } else {
                throw new Exception("索引創建失敗");
            }
