Bullion: A Column Store for Machine Learning

Summary: Bullion is a columnar store tailored for ML: modular cascading encodings, in‑storage feature quantization, optimized long-sequence sparse‑feature encodings, and quality‑aware sequential reads for wide-table/multimodal training. Yields lower I/O for deletion compliance, substantial storage savings on sparse features, and faster metadata parsing than existing column stores. (summarized by gpt-5-mini on Feb 09 2026)
