ElasticSearch7.4批量导入_bulk_综合

请求的每一行包含描述操作说明

的 JSON 对象，第二行为 JSON 对象本身。可以把第一行视为信息行，第二类为数据行。唯一的例

外是 delete 操作，它只包含信息行。来看看下面的例子：

{ "index": { "_index": "addr", "_type": "contact", "_id": 1 }}

{ "name": "Fyodor Dostoevsky", "country": "RU" }

{ "create": { "_index": "addr", "_type": "contact", "_id": 2 }}

{ "name": "Erich Maria Remarque", "country": "DE" }

{ "create": { "_index": "addr", "_type": "contact", "_id": 2 }}

{ "name": "Joseph Heller", "country": "US" }

{ "delete": { "_index": "addr", "_type": "contact", "_id": 4 }}

{ "delete": { "_index": "addr", "_type": "contact", "_id": 1 }}

重要的是，每一个文档或操作说明放置在一行中（以换行符结束）。这意味着无法美化文档格

式。批量索引文件的大小存在限制，它被设定为 100 MB ，在 Elasticsearch 配置文件中可以通过

http.max_content_length 属性来改变。这避免了请求过大时可能存在的请求超时及内存问题。

curl -X POST http://localhost:9200/_bulk -H Content-Type:application/json --data-binary @D:\DevEnv\curl-7.68.0-win64-mingw\bin\xx.json

注意需要导入的文件行与行之间要以换行符相隔，如果导入时提示出错，请将文件内容都归为一行，然后每一行之间以enter回车键相隔开，然后再导入。
