Lesson:aegonkv a high bandwidth low tail latency and low storage cost kv separated lsm store with smart 5a081f42
| 제목 | AegonKV: A High Bandwidth, Low Tail Latency, and Low Storage Cost KV-Separated LSM Store with SmartSSD-based GC Offloading |
|---|---|
| 궁금했던 점 | Can a KV-separated LSM improve throughput, tail latency, and space use simultaneously despite value-log garbage collection? |
| 해본 것 | AegonKV offloads asynchronous GC to SmartSSD compute with offload-friendly data structures and coordinated host/device execution. |
| 당시 조건 | Venue: FAST. Year: 2025.
Host-side GC competes with foreground LSM reads/writes for CPU and I/O, forcing tradeoffs among the three objectives. Verification: official_abstract; confidence=high. |
| 실제 결과 | workloads=KV-separated LSM workloads on SmartSSD; baselines=existing KV-separated systems; metrics=throughput; tail latency; space overhead; results=1.28–3.3x throughput; 37–66% lower tail latency; 15–85% lower space overhead |
| 왜 그랬는지 | Near-data GC can isolate maintenance bandwidth and CPU from the foreground path. |
| 다음에 기억할 것 | Offload bandwidth-heavy maintenance with data structures designed for the near-storage execution environment. |
| 언제 맞는지 | KV-separated LSM stores on computational/SmartSSD platforms.
Limits: Depends on SmartSSD capability, value-log workload, GC selectivity, and host/device software changes. |

Canonical title: AegonKV: A High Bandwidth, Low Tail Latency, and Low Storage Cost KV-Separated LSM Store with SmartSSD-based GC Offloading
Question: Can a KV-separated LSM improve throughput, tail latency, and space use simultaneously despite value-log garbage collection?
Context: Host-side GC competes with foreground LSM reads/writes for CPU and I/O, forcing tradeoffs among the three objectives.
Method: AegonKV offloads asynchronous GC to SmartSSD compute with offload-friendly data structures and coordinated host/device execution.
Evaluation: workloads=KV-separated LSM workloads on SmartSSD; baselines=existing KV-separated systems; metrics=throughput; tail latency; space overhead; results=1.28–3.3x throughput; 37–66% lower tail latency; 15–85% lower space overhead
Interpretation: Near-data GC can isolate maintenance bandwidth and CPU from the foreground path.
Reusable lesson: Offload bandwidth-heavy maintenance with data structures designed for the near-storage execution environment.
Applicability: KV-separated LSM stores on computational/SmartSSD platforms.
Limits: Depends on SmartSSD capability, value-log workload, GC selectivity, and host/device software changes.
