DuetKV is presented, a heterogeneous key-value store that treats NVM and SSD as peer foreground write engines and selects a destination for each request, and achieves up to 3.4 × the throughput of the strongest baseline on write-heavy workloads, while remaining competitive on read-heavy workloads.

Modern heterogeneous storage no longer follows a simple fast/slow hierarchy. Byte-addressable NVM provides fine-grained, low-latency persistence, whereas NVMe SSDs deliver high bandwidth under deep queues and offer greater capacity. Most LSM-tree key-value stores, however, send every foreground write through a designat...

NoFDB is presented, an NVMe-oF-enabled RPKVS design that eliminates redundant index management and reduces replication latency, and introduces a set of system-level optimizations to address the challenges introduced by NVMe-oF and unlock its performance potential.
