What are some alternative caching algorithms I can use?

There are several alternative caching algorithms you can consider, such as LRU (Least Recently Used), LFU (Least Frequently Used), and ARC (Adaptive Replacement Cache). Each has its own advantages depending on your use case.

Can you explain how LRU works?

LRU keeps track of the order in which items are accessed. When the cache reaches its limit, it removes the least recently used item to make space for new data.

What about LFU? How does it differ from LRU?

LFU removes the least frequently used items instead of the least recently used. It tracks how often each item is accessed, making it suitable for scenarios where some data is accessed much more frequently than others.

Are there any scenarios where ARC is preferred?

Yes, ARC is beneficial in environments with varying access patterns. It dynamically adjusts between LRU and LFU strategies, making it more adaptable to changing workloads.
