使用Python将文件导入并保存到NOSQL数据库

import pymongo

# 连接到MongoDB数据库
client = pymongo.MongoClient("mongodb://localhost:27017/")

# 选择数据库和集合
db = client["mydatabase"]
collection = db["mycollection"]

# 将数据插入到集合中
data = {"name": "John", "age": 30}
collection.insert_one(data)

from cassandra.cluster import Cluster

# 连接到Cassandra数据库
cluster = Cluster(['localhost'])
session = cluster.connect()

# 创建键空间和表
session.execute("CREATE KEYSPACE IF NOT EXISTS mykeyspace WITH replication = {'class':'SimpleStrategy', 'replication_factor':1}")
session.execute("CREATE TABLE IF NOT EXISTS mykeyspace.mytable (id UUID PRIMARY KEY, name text, age int)")

# 将数据插入到表中
data = {"id": uuid.uuid4(), "name": "John", "age": 30}
session.execute("INSERT INTO mykeyspace.mytable (id, name, age) VALUES (%s, %s, %s)", (data["id"], data["name"], data["age"]))

import redis

# 连接到Redis数据库
r = redis.Redis(host='localhost', port=6379, db=0)

# 将数据存储为键值对
data = {"name": "John", "age": 30}
r.set("mykey", data)
