The tantivy-object-store from lancedb

tantivy-object-store's Introduction

Developer-friendly, database for multimodal AI

LanceDB is an open-source database for vector-search built with persistent storage, which greatly simplifies retrieval, 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({
  name: 'vectors',
  data:  [
    { 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();

// You can also search for rows by specific criteria without involving a vector search.
const rowsByCriteria = await table.search(undefined).where("price >= 10").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()
