OmniTable: One Logical Table Manages 305B Records Across 35PB for LLM Training

Ant Group's OmniTable system, awarded VLDB 2026 Best Industrial Paper, uses a unified logical wide table to manage 35PB and 305B records for LLM training, reducing end-to-end data preparation from 14 days to 2.5 days via logical-physical separation, feature dependency DAGs, record-level fault tolerance, and operator fusion.
