delete_by_query删除数据(python)

 

from elasticsearch import Elasticsearch
import os, json, urllib, datetime, shutil,random,uuid
import time
import random
from elasticsearch import helpers
from random import choice

if __name__ == '__main__':
    print("开始时间:"+time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))

    es = Elasticsearch(hosts=["http://elastic:elastic@192.168.1.134:19200/"], timeout=30000)
    query = {'query': {'match': {'massive_type': '0'}}}
    es.delete_by_query(index='app_message_all', body=query, params={'scroll_size': '3000', 'slices': '2'})

    print("结束时间:"+time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())))

slices:可以理解为并行度，开启几个进程去删除数据

scroll_size：批次大小
