Improving Range Scan Performance in LSM-trees with Group Caching

Summary: LSM-tree range scans suffer from asymmetric I/O value across levels; Group Cache exploits this by caching minimal KV Groups, the smallest query-relevant sets, instead of blocks or full results. A size-aware policy favors small/high-utility groups and handles compaction/hotness, yielding up to 3x faster scans or same speed with 75% less cache. (summarized by gpt-5-mini on Apr 11 2026)
