Explore a 15-minute conference talk from OSDI '23 that presents Rowan, an innovative RDMA abstraction designed to enhance replication writes in persistent memory (PM) key-value stores (KVSs). Learn how researchers from Tsinghua University address the challenges of combining PM with RDMA for distributed KVSs by introducing a method that aggregates concurrent remote writes and efficiently writes them to PM. Discover how Rowan-KV, a log-structured PM KVS built using this abstraction, outperforms existing replication approaches by significantly boosting throughput, reducing latency, and minimizing device-level write amplification. Gain insights into the potential of this technology to improve the performance of replicated distributed key-value stores in persistent memory environments.
