What are the differences between LRU caching and FIFO caching?

What are the differences between LRU caching and FIFO caching?

LRU (Least Recently Used) caching evicts the least recently accessed items, while FIFO (First In, First Out) removes the oldest items first.

Which one is more efficient for a web application?

LRU is generally more efficient for web applications as it keeps frequently accessed data in cache, reducing load times.

Can you give an example of when to use FIFO caching?

FIFO caching is useful in scenarios where the order of data access is predictable, like streaming data where older data is less relevant.

What are the drawbacks of using LRU caching?

Drawbacks of LRU include higher overhead for tracking access patterns and potential performance issues with large datasets.
