What is the difference between LFU and LRU cache?
An example of an AI chatbot conversation about LFU and LRU caching mechanisms.
What is the difference between LFU and LRU cache?
LFU (Least Frequently Used) cache evicts the least accessed items, while LRU (Least Recently Used) evicts the least recently accessed items.
Can you give an example of when to use LFU over LRU?
Use LFU when you have data that is accessed frequently but not necessarily in a recent timeframe, like user preferences.
What are the advantages of using LRU?
LRU is simple to implement and works well for workloads where recently accessed data is likely to be accessed again.
Are there any downsides to using LFU?
Yes, LFU can be more complex to implement and may not perform well if access patterns change frequently.
