• A Linearizable Key-Value Store for Hardware Disaggregation Architecture. Hardware disaggregation breaks monolithic hardware into separate components (i.e., CPU, memory, and disk) that communicate over the network. Traditional monolithic key-value stores deliver poor performance with disaggregated hardware. This project investigates building a strongly consistent key-value store that takes into consideration the hardware disaggregation architecture and overcomes the challenges of hardware disaggregation such as the overhead of data transfer and the limited memory of CPU nodes.
• LoLKV: The Logless Linearizable Key-Value Storage System. We build a replicated key-value store that utilizes RDMA for communication. LoLKV forgoes the classical log-based design and uses a lock-free approach to allow multiple threads to concurrently update objects. LoLKV employs a novel leader election and consolidation approach to handle complex failure scenarios.
