LoLKV - Logless, Linearizable, RDMA-based Key-Value Storage System

Explore a groundbreaking approach to key-value storage systems in this 14-minute conference talk from NSDI '24. Delve into LoLKV, a novel logless replicated key-value storage system that challenges traditional log-based designs. Learn how LoLKV employs a lock-free approach, enabling concurrent object updates by multiple threads. Discover the innovative leader election and consolidation technique developed to manage complex failure scenarios. Understand the benefits of LoLKV's passive followers in reducing overall CPU usage. Examine the impressive performance gains, with LoLKV achieving 1.7–10× higher throughput and 20–92% lower tail latency compared to other state-of-the-art low-latency key-value stores. Gain insights from the research team at the University of Waterloo and Oracle Labs as they present their findings on this cutting-edge RDMA-based storage system.
