2 days ago LFU (Least Frequently Used)
When to use: Access patterns have frequent usage of specific keys, and recently used data isn't always the most important.
How it works: Evicts the least frequently accessed items, regardless of recency.
Benefits:
- Retains frequently accessed data over time.
- Prevents eviction of "hot" keys used repeatedly but not recently.
Drawbacks: More complex to implement and manage than LRU.
An LRU (Least Recently Used) cache is widely used for its simplicity and effectiveness in managing limited resources. However, there are scenarios where other caching algorithms might perform better depending on your requirements. So Discache must have other algo capabilities for tacking other use cases effectively.
