How do I implement in-memory caching in my application?

To implement in-memory caching, you can use libraries like Redis or Memcached. Which programming language are you using?

I'm using Python. Can you give me a code example?

Sure! You can use the cachetools library. Here's a simple example:

from cachetools import LRUCache

cache = LRUCache(maxsize=100)

def get_data(key):
    if key in cache:
        return cache[key]
    else:
        # Simulate data fetching
        data = fetch_data_from_db(key)
        cache[key] = data
        return data

What are the benefits of using in-memory caching?

In-memory caching improves performance by reducing database load, speeding up data retrieval, and enhancing user experience.
