It offers 100x faster random access than Parquet while maintaining scan performance, includes built-in vector search capabilities, automatic versioning, and integrates with popular data tools like Pandas, DuckDB, and Polars. The format addresses the multi-stage ML development cycle by providing a unified solution for data collection, analytics, feature engineering, and training, eliminating the need for multiple data format conversions. ## Full article daily.dev links to this article rather than hosting it.
