Our verdict on Lance

Lance is an open-source file format, table format, and catalog specification for teams managing multimodal AI data. It is designed for machine-learning training, feature engineering, search systems, and lakehouse deployments. The format stores text, images, video, audio, and embeddings, while supporting dataset versioning, branching, tagging, rollback, and historical-version access. Its data scope covers files and tables, with table-level snapshots and bring-your-own storage.

Version control is a central strength. Lance supports time-travel queries, ACID transactions, and snapshot isolation, giving teams a structured way to work with historical dataset states. Schema and data evolution can happen without full table rewrites, which fits datasets that change as training inputs, annotations, and features develop. Search is another standout area: vector similarity search, full-text search, and hybrid search are included alongside SQL analytics. These capabilities make Lance a strong fit when versioned storage and retrieval need to sit close to AI data.

Its ecosystem connections also suit teams with varied data and machine-learning stacks. Published integrations include Apache DataFusion, Apache Spark, DuckDB, Trino, PyTorch, TensorFlow, Ray, Hugging Face, PostgreSQL, Apache Flink, Pandas, Polars, and Apache Arrow. Object-storage support covers S3, Azure Blob Storage, and Google Cloud Storage. Lance is self-hosted and is not a hosted SaaS product, so teams should choose it when they want control over deployment and storage architecture. Organizations seeking a managed service with vendor-operated infrastructure should consider a different type of product.

I've used Lance myself and this is my honest opinion — nobody paid or asked me to write it.
