前言

使用bulk命令，批量执行，用于增删改的操作，用于提高效率！

注意：在一个命令结束前，命令头里面的代码不能换行；

删除、修改命令有请求头和请求体，这两部分需要换行！

metadata 需要指明需要被操作文档的_index，_type以及_id

举例

POST /_bulk
{"delete": {"_index": "test_index","_type": "test_type","_id": "1"}}
{"create": {"_index": "test_index","_type": "test_type","_id": "4"}}
{"desc": "id is 4"}
{"index": {"_index": "test_index","_type": "test_type","_id": "2"}}
{"age": 100}
{"index": {"_index": "test_index","_type": "test_type","_id": "5"}}
{"desc": "id is 5"}
{"update": {"_index": "test_index","_type": "test_type","_id": "3"}}
{"doc":{"desc": "id is update to 3333"}} 

解析

1.删除命令

删除命令是只有一行，没有请求体：

{"delete": {"_index": "test_index","_type": "test_type","_id": "1"}}

2.增加命令

请求头和请求体需要换行！

{"create": {"_index": "test_index","_type": "test_type","_id": "4"}}

{"desc": "id is 4"}

或者使用index命令，

{"index": {"_index": "test_index","_type": "test_type","_id": "5"}}

{"desc": "id is 5"}

3.修改命令

请求头和请求体需要换行！

{"update": {"_index": "test_index","_type": "test_type","_id": "3"}}

{"doc":{"desc": "id is update to 3333"}}

或者使用index命令

{"index": {"_index": "test_index","_type": "test_type","_id": "2"}}

{"age": 100}

OK,GAME OVER!
