PolarFS: An Ultra-low Latency and Failure Resilient Distributed File System for Shared Storage Cloud Database
Summary: PolarFS delivers near-local SSD write latency via user-space networking/I/O stacks leveraging RDMA, NVMe, and SPDK. Its ParallelRaft protocol relaxes Raft serialization using databases’ tolerance for out-of-order I/O, improving replicated-storage scalability. (summarized by gpt-5.6-luna on Jul 24 2026)
