This conference talk presents AegonKV, a novel key-value separated LSM store that simultaneously addresses three critical challenges in storage systems: throughput, tail latency, and space usage. Learn how researchers from Huazhong University of Science and Technology developed a "three-birds-one-stone" solution that leverages SmartSSD-based garbage collection offloading to enhance performance without competing for CPU or I/O resources. The presentation demonstrates how AegonKV achieves 1.28-3.3 times throughput improvement, 37%-66% reduction in tail latency, and 15%-85% reduction in space overhead compared to existing KV separated systems. Discover the offload-friendly data structures and hardware/software execution logic that overcome the challenges of garbage collection in key-value separated storage systems.
