🤗 Lance x Hugging Face: A New Era of Sharing Multimodal Data on the Hub

Lance x HuggingFace

Lance now has native support on the Hugging Face Hub, allowing large multimodal datasets — including blobs, embeddings, and indexes — to be published as a single searchable artifact.

Developers can scan Lance tables directly from the Hub using either the 🤗 datasets API or Lance's dataset API and immediately run SQL and vector search in just a few lines of code, reducing friction between sharing datasets and running production-grade retrieval workflows.

🪾 Branching and Shallow Cloning in Lance: Towards a "Git for AI Data"

Branching and Shallow Cloning in Lance

Lance introduces a branching model designed for large-scale AI experimentation, combining independent manifest trees, physical isolation per branch, immutable tags, and zero-copy shallow clones via multi-base snapshots.

Unlike traditional table formats that share metadata across branches, Lance avoids shared bottlenecks and cache invalidation, enabling full time travel and high-concurrency experimentation without impacting production workloads.

🏔️ How We Added Geospatial Support To Lance With No New Code

Geospatial in Lance

Geospatial support landed in Lance with no storage format changes. As an Arrow-native system, Lance supports GeoArrow types end-to-end, integrates geospatial functions directly into DataFusion, and uses a production R-Tree index to accelerate spatial predicates—enabling geospatial filters, vector search, and SQL over metadata to run in a single multimodal query plan.

This work was driven by Xin Sun (ByteDance), with contributions from Jay Narale (Uber), Kyle Barron (GeoArrow / GeoDataFusion), and Tim Saucer (Rerun & Apache DataFusion).
