MLSkip: Data Skipping for ML Filters via Lightweight Metadata

arXiv:2606.03946v1 Announce Type: cross Abstract: Database vendors recently released AI functions that can be used in filter predicates. As such functions often rely on costly, black-box ML models, they unveil new data management challenges. Concretely, traditional data skipping techniques for integer and string data fail to be applicable to the new filter type. Indeed, there is no known mechanism for pruning non-qualifying row groups, e.g., when reading files from blob storage. In this work, we initiate the study of data skipping techniques for ML filters. We make the case that Parquet's defa

Why this matters
Why now

The increasing use of AI functions within databases necessitates new data management techniques to handle their computational cost and black-box nature, departing from traditional data skipping methods.

Why it’s important

This work directly addresses the efficiency bottleneck of integrating costly ML models into database filter predicates, which is critical for scaling AI-driven data processing and reducing operational costs.

What changes

The proposed 'MLSkip' mechanism introduces a method for intelligent data skipping specifically tailored for ML filters, improving performance and resource utilization for database queries involving AI functions.
