DiaLSM: Towards Write-Stall-Free Performance via Shard-based LSM-tree
Hongsu Byun, Safdar Jamil, Honghyeon Yoo +5
Log-Structured Merge-tree (LSM) aims to achieve high write throughput, but is known to experience the write stall problems when subjected to sustained write pressure. We quantify t…
DUAL-BLADE: Dual-Path NVMe-Direct KV-Cache Offloading for Edge LLM Inference
Bodon Jeong, Hongsu Byun, Youngjae Kim +4
The increasing deployment of Large Language Model (LLM) inference on edge AI systems demands efficient execution under tight memory budgets. A key challenge arises from Key-Value (…
RESYSTANCE: Unleashing Hidden Performance of Compaction in LSM-trees via eBPF
Hongsu Byun, Seungjae Lee, Honghyeon Yoo +2
The development of high-speed storage devices such as NVMe SSDs has shifted the primary I/O bottleneck from hardware to software. Modern database systems also rely on kernel-based…
A Host-SSD Collaborative Write Accelerator for LSM-Tree-Based Key-Value Stores
KiHwan Kim, Hyunsun Chung, Seonghoon Ahn +6
Log-Structured Merge (LSM) tree-based Key-Value Stores (KVSs) are widely adopted for their high performance in write-intensive environments, but they often face performance degrada…
An Analytical Model-based Capacity Planning Approach for Building CSD-based Storage Systems
Hongsu Byun, Safdar Jamil, Jungwook Han +5
The data movement in large-scale computing facilities (from compute nodes to data nodes) is categorized as one of the major contributors to high cost and energy utilization. To tac…
