We present LoLKV, a novel logless replicated key-value storage system. LoLKV follows a fundamentally different approach for designing a linearizable key-value storage system compared to state-of-the-art systems. LoLKV forgoes the classical log-based design and uses lock-free approach to allow multiple threads to concurrently update objects. It presents a novel leader election and consolidation approach to handle complex failure scenarios. LoLKV’s followers are passive, reducing their overall CPU usage. Our evaluation shows that LoLKV achieves 1.7–10x higher throughput and 20–92% lower tail latency than other state-of-the-art low-latency key-value stores.
