OmniTable: A Unified Wide-Table System for Petabyte-Scale LLM Data Curation and Exploration
Summary: OmniTable unifies petabyte-scale heterogeneous LLM corpora and thousands of derived features behind one logical wide-table schema while physically separating storage. Declarative lifecycle management, adaptive CPU/GPU execution, lineage, and hybrid exploration reduce curation cycles 5.6× across 35 PB. (summarized by gpt-5.6-luna on Aug 28 2026)
