How does LFU caching work in practice?
An example of an AI chatbot conversation about LFU caching implementation and its benefits.
How does LFU caching work in practice?
LFU, or Least Frequently Used, caching keeps track of how often items are accessed. It evicts the least frequently accessed items first.
Can you give me an example of LFU in a web application?
Sure! In a web application, LFU can be used to cache user session data. If a user accesses certain sessions more frequently, those sessions remain in cache.
What are the advantages of using LFU over LRU?
LFU can be more efficient for workloads with repeated access patterns, as it prioritizes frequently used items, potentially reducing cache misses.
Are there any downsides to using LFU?
Yes, LFU can be more complex to implement and may require more memory to track access frequencies compared to simpler algorithms like LRU.
