Enabling Low Tail Latency on Multicore Key-Value Stores

Summary: RStore is a multicore KVS whose primary goal is low tail latency rather than throughput, achieved via asynchronous programming, message-passing, and log-structured storage on modern hardware. It scales with cores while keeping low, predictable latency, contrasting traditional KVS designs. (summarized by gpt-5-nano on Feb 09 2026)
