Embedded, written in Rust. - Fast for time-series shape: over 4.5× faster than DuckDB and Polars on OHLCV+VWAP rollups over 20M rows. - Native time-series SQL: ASOF join, timezone-aware time bucket , gapfill/resample, rolling windows, vwap , ewma . - Point-in-time reads: pin a decision time and the frame that reaches pandas cannot contain rows from after it. No lookahead bias, by construction. - Efficient event-driven backtester: 3.05M events/s through the replay kernel, 11.7× NautilusTrader and 31× LEAN on a shared top-of-book workload. - Native venue support: Kalshi, Polymarket, Hyperliquid, Binance and more. - Professional statistical analysis: factor and performance metrics at alphalens and empyrical parity, plus deflated Sharpe and overfitting-probability detection. - In-terminal notebooks: agents and humans explore data without leaving the shell. h5i-db nb view runs ordinary .ipynb files on a real Jupyter kernel and draws matplotlib plots inline. - Fork a database in milliseconds: forks share data instead of copying it. Agents can run wide trial-and-error loops (fork, mutate, evaluate, discard) at almost zero cost. - Every write is an atomic, versioned commit: any past version reads in O(1), so a bad ingest (human or agent) is one restore away from undone. - Safety policies for agent writes: previewable mutations, policy gates, fail-clo","default_branch":null,"files":null,"tree":[],"storefront":"/r/Koukyosyumei","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/Koukyosyumei/h5i-db/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
