What are the benefits of using an LFU cache?
LFU cache, or Least Frequently Used cache, optimizes memory usage by keeping the most accessed data. This improves performance.
How does LFU compare to LRU?
LFU focuses on access frequency, while LRU (Least Recently Used) prioritizes recency. LFU can be better for stable access patterns.
Can LFU cache reduce latency?
Yes, by storing frequently accessed data, LFU cache can significantly reduce latency for data retrieval.
What are some use cases for LFU caching?
Common use cases include web caching, database query caching, and applications with predictable access patterns.
Are there any downsides to using LFU?
Yes, LFU can be complex to implement and may require more memory overhead compared to simpler caching strategies.
