个人博客地址：Python3操作MongoDB批量upsert | 一张假钞的真实世界
代码如下：
mongoClient = MongoClient('mongodb://172.16.72.213:27017/')
opsDb = mongoClient.ops
azScheduled = opsDb.azScheduledFlow
bulkOpers = []
for flow in scheduledFlows.values():
bulkOpers.append(UpdateOne({'opsDt': opsDt, 'projectId': flow['projectId'], 'projectName': flow['projectName'], 'flowName': flow['flowName']}, {'$set': {'opsDateTime': opsDtStr, 'status': flow['status'], 'startTime': flow['startTime'], 'endTime': flow['endTime'], 'elapsed': flow['elapsed']}}, upsert=True))
azScheduled.bulk_write(bulkOpers)
