Architecturevector-rag / multimodal columnar lakehouse
DetailsLanceDB is built on the Lance columnar format, enabling zero-copy access to multimodal data (text, images, video, point clouds) stored directly on disk or object storage. It is embeddable (no server required) with Python/Rust/JavaScript bindings, supports ANN and full-text search, and can be scaled to petabytes. The serverless cloud offering adds collaboration and persistence without infrastructure management.
