## Summary

Databricks releases UCDataset in Beta on AI Runtime, a PyTorch data loader that streams Unity Catalog tables directly to every GPU in a training job without exports or copies. On a simulated 300 GB recommendation workload across 8 NVIDIA H100 GPUs, Databricks reports an average 10x training-time improvement over reading an exported Parquet copy. The Beta reads Delta tables and cannot yet read tables with row filters or column masks.
