Elasticsearch使用bulk批量執行命令
阿新 • • 發佈：2019-02-01
前言
使用bulk命令，批量執行，用於增刪改的操作，用於提高效率！
注意：在一個命令結束前，命令頭裡面的程式碼不能換行；
刪除、修改命令有請求頭和請求體，這兩部分需要換行！
metadata 需要指明需要被操作文件的_index，_type以及_id
舉例
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.刪除命令
刪除命令是隻有一行，沒有請求體：
{"delete": {"_index": "test_index","_type": "test_type","_id": "1"}}
2.增加命令
請求頭和請求體需要換行！
{"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
請求頭和請求體需要換行！
{"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"}}
