个人博客地址：Python3连接MongoDB并写入数据 | 一张假钞的真实世界

安装PyMongo

$ pip3 install pymongo
Successfully installed pymongo-3.7.2

连接MongoDB并且批量插入操作

#!/usr/bin/python3

import mysql.connector
import gzip
import json
from pymongo import MongoClient
from datetime import datetime

opsDateTime = datetime.now().isoformat(timespec='seconds')

config = {
    'user': 'roHive',
    'password': 'hive@bigdata!23',
    'host': '172.16.72.22',
    'database': 'azkaban3',
    'raise_on_warnings': True,
    'charset': 'latin1'
}

cnx = mysql.connector.connect(**config)
cursor = cnx.cursor()
query = ("SELECT trigger_id, data FROM azkaban3.triggers")
cursor.execute(query)

scheduledList = []
for (triggerId, triggerData) in cursor:
    triggerJson = json.loads(gzip.decompress(bytes(triggerData, encoding='latin1')))
    actionJson = triggerJson['actions'][0]['actionJson']
    projectName = actionJson['projectName']
    flowName = actionJson['flowName']
    scheduledFlow = {'opsDateTime': opsDateTime, 'projectName': projectName, 'flowName': flowName}
    scheduledList.append(scheduledFlow)

cursor.close()
cnx.close()

mongoClient = MongoClient('mongodb://172.16.72.213:27017/')
opsDb = mongoClient.ops
azScheduled = opsDb.azScheduledFlow
azScheduled.insert_many(scheduledList)
