Proximity

Proximity is a research project exploring the optimization and speed-recall tradeoffs of approximate vector search in high-dimensional spaces. We provide an approximate cache for vector databases that is written in Rust and exposes Python bindings.

More information is available in our EuroMLSys '25 publication.

Note: This code is under active development and is not recommended for production systems.

Installation

Prerequisites

Ensure you have the following dependencies installed:

• the Rust toolkit (Cargo and rustup are encouraged). For now, nightly is required, but a regular (non-nightly) install on your machine will automatically download the nightly compiler and use it only in this project, making this effectively transparent for the user.
• Python 3.8+
• Maturin for Rust-Python interactions (we recommend installing by running pip install maturin)

Build Instructions

python3 -m venv proxi-env
source proxi-env/bin/activate
git clone https://gitlab.epfl.ch/randl/proximity.git
cd proximity/bindings
maturin develop -r
