| 제목 | KVACCEL: A Novel Write Accelerator for LSM-Tree-Based KV Stores with Host-SSD Collaboration |
|---|---|
| 궁금했던 점 | Can one SSD support both block and key-value paths while accelerating LSM-tree writes without violating consistency? |
| 해본 것 | KVACCEL partitions NAND between block and KV interfaces, uses the KV region as a temporary write buffer, and adds an in-device LSM buffer plus range-scan iterator. |
| 당시 조건 | Venue: IPDPS. Year: 2025.
Host-managed LSM stores suffer write stalls and overhead, while KV SSDs alone do not preserve the conventional block interface. Verification: conference paper PDF, DOI metadata, and arXiv preprint; confidence=high. |
| 실제 결과 | workloads=write-intensive and mixed read/write key-value workloads; baselines=ADOC and conventional paths; metrics=throughput and CPU efficiency; results=up to 17% throughput gain on write-intensive workloads; comparable mixed-workload performance |
| 왜 그랬는지 | A KV namespace can act as a pressure-relief tier for the host LSM while block compatibility is retained. |
| 다음에 기억할 것 | Use device interfaces according to data lifetime and write-path urgency, with an explicit reconciliation protocol. |
| 언제 맞는지 | LSM-based stores on programmable dual-interface SSDs.
Limits: Requires modified dual-interface SSD firmware; the headline gain is for write-intensive workloads. |

Canonical title: KVACCEL: A Dual-Interface SSD Architecture for Key-Value Storage Acceleration
Question: Can one SSD support both block and key-value paths while accelerating LSM-tree writes without violating consistency?
Context: Host-managed LSM stores suffer write stalls and overhead, while KV SSDs alone do not preserve the conventional block interface.
Method: KVACCEL partitions NAND between block and KV interfaces, uses the KV region as a temporary write buffer, and adds an in-device LSM buffer plus range-scan iterator.
Evaluation: workloads=write-intensive and mixed read/write key-value workloads; baselines=ADOC and conventional paths; metrics=throughput and CPU efficiency; results=up to 17% throughput gain on write-intensive workloads; comparable mixed-workload performance
Interpretation: A KV namespace can act as a pressure-relief tier for the host LSM while block compatibility is retained.
Reusable lesson: Use device interfaces according to data lifetime and write-path urgency, with an explicit reconciliation protocol.
Applicability: LSM-based stores on programmable dual-interface SSDs.
Limits: Requires modified dual-interface SSD firmware; the headline gain is for write-intensive workloads.
