Chang She b02370cacd feat: LocalTable for vectordb now supports filters without vector search (#693)
Note this currently the filter/where is only implemented for LocalTable
so that it requires an explicit cast to "enable" (see new unit test).
The alternative is to add it to the Table interface, but since it's not
available on RemoteTable this may cause some user experience issues.

LanceDB Multimodal Search


LanceDB is an open-source database for vector-search built with persistent storage, which greatly simplifies retrevial, filtering and management of embeddings.

The key features of LanceDB include:

  • Production-scale vector search with no servers to manage.

  • Store, query and filter vectors, metadata and multi-modal data (text, images, videos, point clouds, and more).

  • Support for vector similarity search, full-text search and SQL.

  • Native Python and Javascript/Typescript support.

  • Zero-copy, automatic versioning, manage versions of your data without needing extra infrastructure.

  • GPU support in building vector index(*).

  • Ecosystem integrations with LangChain 🦜🔗, LlamaIndex 🦙, Apache-Arrow, Pandas, Polars, DuckDB and more on the way.

LanceDB's core is written in Rust 🦀 and is built using Lance, an open-source columnar format designed for performant ML workloads.

Quick Start

Javascript

npm install vectordb
const lancedb = require('vectordb');
const db = await lancedb.connect('data/sample-lancedb');

const table = await db.createTable('vectors',
      [{ id: 1, vector: [0.1, 0.2], item: "foo", price: 10 },
       { id: 2, vector: [1.1, 1.2], item: "bar", price: 50 }])

const query = table.search([0.1, 0.3]).limit(2);
const results = await query.execute();

Python

pip install lancedb
import lancedb

uri = "data/sample-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]).limit(2).to_pandas()
