Lesson:on performance stability in lsm based storage systems e473bf0c
| 제목 | On Performance Stability in LSM-based Storage Systems |
|---|---|
| 궁금했던 점 | Which compaction scheduling choices make LSM write performance stable rather than periodically stalling? |
| 해본 것 | The study uses a two-phase experimental methodology to isolate merge-policy and scheduler behavior under a fixed I/O bandwidth budget. |
| 당시 조건 | Venue: PVLDB. Year: 2019.
Average throughput can hide severe short-term stalls caused by merge backlog and I/O contention. Verification: full_text; confidence=high. |
| 실제 결과 | workloads=Apache AsterixDB LSM experiments; baselines=alternative merge schedulers and compaction policies; metrics=write stalls; throughput variance; I/O bandwidth; results=no single quantitative headline in primary abstract |
| 왜 그랬는지 | Compaction should be evaluated by temporal stability and bandwidth debt, not only aggregate throughput. |
| 다음에 기억할 것 | Measure background-maintenance systems with time-series tail behavior as well as averages. |
| 언제 맞는지 | LSM storage engines and merge schedulers.
Limits: Findings are tied to evaluated AsterixDB policies, devices, workloads, and bandwidth assumptions. |
| 신뢰도 | 낮음 |

Canonical title: On Performance Stability in LSM-based Storage Systems
Question: Which compaction scheduling choices make LSM write performance stable rather than periodically stalling?
Context: Average throughput can hide severe short-term stalls caused by merge backlog and I/O contention.
Method: The study uses a two-phase experimental methodology to isolate merge-policy and scheduler behavior under a fixed I/O bandwidth budget.
Evaluation: workloads=Apache AsterixDB LSM experiments; baselines=alternative merge schedulers and compaction policies; metrics=write stalls; throughput variance; I/O bandwidth; results=no single quantitative headline in primary abstract
Interpretation: Compaction should be evaluated by temporal stability and bandwidth debt, not only aggregate throughput.
Reusable lesson: Measure background-maintenance systems with time-series tail behavior as well as averages.
Applicability: LSM storage engines and merge schedulers.
Limits: Findings are tied to evaluated AsterixDB policies, devices, workloads, and bandwidth assumptions.
