Question: Can LSM-tree compaction policies be expressed as a systematic design space rather than isolated named strategies? Context: Compaction choices trade write, read, and space amplification, but prior systems mix several design decisions. Method: The paper decomposes compaction into trigger, data layout, granularity, and data movement, then instantiates and analyzes ten strategies. Evaluation: workloads=ten instantiated compaction strategies; baselines=representative leveling, tiering, and hybrid policies; metrics=write amplification; write throughput; point lookup; range lookup; space amplification;...; results=12 empirical observations; seven design takeaways; no universal winner Interpretation: Separating policy primitives reveals which choice causes each tradeoff and enables deliberate hybrid designs. Reusable lesson: Factor a policy into orthogonal primitives before comparing implementations. Applicability: LSM key-value stores and compaction-policy design.
