Whenever you're ready, walk me through how you'd approach this.
What are the trade-offs between different caching strategies like LRU, LFU, and ARC in practice?
Compare how LRU, LFU, and ARC make eviction decisions, including their behavior under temporal locality, frequency-based access, workload changes, and sequential scans. Discuss implementation overhead, memory cost, operational complexity, and how you would choose a strategy for a production cache.
Keep the answer focused on general-purpose in-memory caching and practical workload characteristics.
