Sampling-based Predictive Database Buffer Management
Summary: Sampling-based predictive buffer manager uses scan-progress estimates to approximate optimal future-aware evictions for concurrent OLAP scans. Evicting from small tunable samples keeps overhead low and cuts I/O up to 40% vs Clock-sweep/prior predictive methods. (summarized by gpt-5-mini on Feb 09 2026)
