Lucene cuVS

This is a codec for connecting cuVS, NVIDIA's GPU accelerated vector search library, into Apache Lucene.

Overview

The cuVS library is plugged in as a new KnnVectorFormat via a custom codec.

Caution

This is not production ready yet.

Prerequisites

• CUDA 12.0+,
• Maven 3.9.6+,
• JDK 22

Building

mvn clean compile package

The artifacts would be built and available in the target / folder.

Run Tests

export LD_LIBRARY_PATH={ PATH TO YOUR LOCAL libcuvs_c.so }:$LD_LIBRARY_PATH && mvn clean test

Note

The code style format is automatically enforced (including the missing license header, if any) using the Spotless maven plugin. This currently happens in the maven's validate stage.
