What are the performance benefits of using an LRU cache?
An LRU (Least Recently Used) cache improves performance by storing frequently accessed data, reducing retrieval time.
How does it decide which items to remove from the cache?
It removes the least recently used items when the cache reaches its limit, ensuring that the most relevant data stays available.
Can you give me an example of where an LRU cache would be beneficial?
Sure! LRU caches are great for web applications that need to store user session data or frequently accessed database queries.
Are there any downsides to using an LRU cache?
Yes, LRU caches can consume more memory and may introduce overhead in maintaining the order of items.
