Accelerating String-key Learned Index Structures via Memoization-based Incremental Training
Summary: SIA accelerates variable-length string-key learned-index retraining via memoized incremental matrix decomposition, recomputing only updated keys and reusing prior results. FPGA offloading further boosts training and query throughput, achieving 2.6–3.4× gains over ALEX, LIPP, and SIndex. (summarized by gpt-5.6-luna on Jul 24 2026)
