ReStore: A Reinforcement Learning Approach for Data Migration in Multi-Tiered Storage
Summary: ReStore uses per-tier reinforcement-learning agents for adaptive, page-level migration, jointly modeling access patterns and SSD read/write asymmetry and parallelism. It delivers up to 6× lower runtime and 48× fewer migrations across benchmarks and traces. (summarized by gpt-5.6-luna on Jul 26 2026)
