+
+ +
+ +LanceDB is an open-source database for vector-search built with persistent storage, which greatly simplifies storage, retrieval and filtering for vectors and more. + +The key features of Lance include: + +* Scale to billion+ vector-search all without managing servers. + +* Combine attribute-based information with vectors and store them as a single source-of-truth. + +* Zero-copy, automatic versioning, manage versions of your data without needing extra infrastructure. + +* Ecosystem integrations: Apache-Arrow, Pandas, Polars, DuckDB and more on the way. + +Lance's core is written in Rust 🦀 and is built using Lance, an open-source columnar format designed for performant ML workloads. + +## Quick Start + +**Installation** + +```shell +pip install lancedb +``` + +**Quickstart** +```python +import lancedb + +db = lancedb.connect(uri) +table = db.create_table("my_table", + data=[{"vector": [3.1, 4.1], "item": "foo", "price": 10.0}, + {"vector": [5.9, 26.5], "item": "bar", "price": 20.0}]) +result = table.search([100, 100]).where("price < 15").limit(1).to_df() +```
