The LRU-K Page Replacement Algorithm For Database Disk Buffering

Summary: LRU-K tracks the last K references per page to estimate interarrival times and drive per-page eviction decisions. Self-tuning with lightweight bookkeeping, it adapts in real time, outperforming conventional buffering and approaching manually tuned, workload-specific pools.
