When should I use LRU caching?

Can you explain when to use LRU caching?

LRU caching is best used when you have limited memory and need to keep frequently accessed data available.

What are the benefits of using LRU over other caching strategies?

LRU efficiently manages memory by evicting the least recently used items, which often improves performance.

Are there any downsides to using LRU caching?

Yes, LRU can introduce overhead due to tracking usage order, and it may not be optimal for all access patterns.

In what scenarios would LRU not be the best choice?

LRU may not be ideal for workloads with predictable access patterns or when data access is uniform.
