Redis persistent storage database

Redis persistent storage database

Redis is a high-performance key-value storage database that is often used in scenarios such as caching, message brokering, and session management. In order to ensure the reliability and durability of data, Redis provides two persistent storage methods: RDB (Redis Database) and AOF (Append-Only File).

1. RDB persistence:
   RDB persistence saves the Redis data set to the disk in binary form. It is done by writing a Redis snapshot of the data set at a certain point in time to disk. The advantage of RDB persistence is that the generated RDB files are compact and easy to back up, making them suitable for disaster recovery. Here is a sample code using RDB persistence:

# 导入Redis模块
import redis

# 创建Redis连接
r = redis.Redis(host='localhost', port=6379, db=
