H2O: A Hands-free Adaptive Store

Summary: H2O supports multiple storage layouts within a single engine and adapts layout choices on-the-fly per query. No fixed storage design; data parts are materialized in patterns per workload, yielding best-case performance across workloads without tuning. (summarized by gpt-5-nano on Feb 09 2026)
