How can I implement caching in databases?

Implementing caching in databases can significantly improve performance. You can use in-memory data stores like Redis or Memcached. Would you like to know how to set up Redis for caching?

Yes, please explain how to set up Redis for caching.

To set up Redis, first install it on your server. Then, configure your application to connect to the Redis server. You can use libraries like redis-py for Python or node-redis for Node.js. Would you like a code example?

A code example would be great!

Here's a simple example in Python using redis-py:

import redis

# Connect to Redis
r = redis.Redis(host='localhost', port=6379, db=0)

# Set a value
r.set('key', 'value')

# Get a value
value = r.get('key')
print(value)

This code connects to a local Redis instance, sets a key-value pair, and retrieves it.
