MLSkip: Data Skipping for ML Filters via Lightweight Metadata
Researchers have developed MLSkip, a novel technique to improve data skipping for machine learning filters in databases. Traditional methods are ineffective with costly, black-box ML models used in filter predicates. MLSkip leverages Parquet's min-max metadata and neural network verification to prune non-qualifying data groups, achieving up to 38.31% effectiveness. This approach offers an end-to-end speedup of 1.07x over PyTorch in DuckDB. AI
