How to implement redis cache

The implementation of Redis cache requires the following steps:

1. Installing Redis: First you need to install the Redis server on your system.

2. Connect to Redis: Use the Redis client to connect to the Redis server.

3. Store data into Redis: Use Redis client operations to store data into a Redis server.

4. Fetch data: Use Redis client operations to fetch data from a Redis server.

5. Set cache expiration time: You can set an expiration time for data stored in Redis, so that the data will be deleted from Redis after it expires.

These steps can be implemented using Redis client libraries in various languages ​​such as Java, Python, Ruby, etc.
