infinity: A C++ repository from cauliyang

The AI-native database built for LLM applications, providing incredibly fast vector and full-text search

Roadmap 2024 | Twitter | Discord | YouTube |

Infinity is a cutting-edge AI-native database that provides a wide range of search capabilities for rich data types such as vectors, full-text, and structured data. It provides robust support for various LLM applications, including search, recommenders, question-answering, conversational AI, copilot, content generation, and many more RAG (Retrieval-augmented Generation) applications.

🌟 Key Features

Infinity comes with high performance, flexibility, ease-of-use, and many features designed to address the challenges facing the next-generation AI applications:

⚡️ Incredibly fast

Achieves 0.1 milliseconds query latency on million-scale vector datasets.
Up to 10K QPS on million-scale vector datasets.

See the Benchmark report for more information.

🔮 Fused search

Supports a fused search of multiple embeddings and full text, in addition to filtering.

🍔 Rich data types

Supports a wide range of data types including strings, numerics, vectors, and more.

🎁 Ease-of-use

Intuitive Python API. See the Python API
A single-binary architecture with no dependencies, making deployment a breeze.

🎮 Get Started

Deploy Infinity database

Deploy using binary package on Linux x86_64

You can download the binary package (deb, rpm, or tgz) for your respective host operating system from https://github.com/infiniflow/infinity/releases. These packages are designed to be compatible with Linux x86_64 hosts that are no older than CentOS 7. They are statically linked, except for glibc. For example:

sudo rpm -i infinity-0.1.0-dev-x86_64.rpm
sudo systemctl start infinity

Deploy using Docker on Linux x86_64 and MacOS x86_64

docker pull infiniflow/infinity:nightly
docker run -d --name infinity -v /tmp/infinity/:/tmp/infinity --network=host infiniflow/infinity:nightly

Install Infinity's Python client

pip install infinity_sdk

Import necessary modules

import infinity
import infinity.index as index
from infinity.common import REMOTE_HOST

Connect to the remote server

infinity_obj = infinity.connect(REMOTE_HOST)

Get a database

db = infinity_obj.get_database("default")

Create a table

# Drop my_table if it already exists
db.drop_table("my_table", if_exists=True)
# Create a table named "my_table"
table = db.create_table("my_table", {"num": "integer", "body": "varchar", "vec": "vector, 4, float"}, None)

Insert two records

table.insert([{"num": 1, "body": "unnecessary and harmful", "vec": [1.0, 1.2, 0.8, 0.9]}])
table.insert([{"num": 2, "body": "Office for Harmful Blooms", "vec": [4.0, 4.2, 4.3, 4.5]}])

Execute a vector search

res = table.output(["*"]).knn("vec", [3.0, 2.8, 2.7, 3.1], "float", "ip", 2).to_pl()
print(res)
