redis数据同步到mysql

# 示例代码：使用Kafka进行数据同步
from kafka import KafkaProducer

producer = KafkaProducer(bootstrap_servers='localhost:9092')

def sync_data_to_mysql(data):
    # 将数据写入MySQL
    pass

def on_redis_change(key, value):
    producer.send('redis_to_mysql_topic', key=key, value=value)
    producer.flush()

# 监听Redis变化并发送消息到Kafka

# 示例代码：异步同步数据
import asyncio

async def async_sync_data_to_mysql(data):
    # 异步写入MySQL
    pass

async def on_redis_change_async(key, value):
    await async_sync_data_to_mysql(value)

# 监听Redis变化并异步同步数据

# 示例代码：使用事务机制进行数据同步
import pymysql

def sync_data_to_mysql_with_transaction(data):
    conn = pymysql.connect(host='localhost', user='user', password='password', db='db')
    try:
        with conn.cursor() as cursor:
            # 开启事务
            conn.begin()
            # 插入数据
            sql = "INSERT INTO table (key, value) VALUES (%s, %s)"
            cursor.execute(sql, (data['key'], data['value']))
            # 提交事务
            conn.commit()
    except Exception as e:
        # 回滚事务
        conn.rollback()
        raise e
    finally:
        conn.close()
