VectorChord Migration Overview

From PGVecto.rs

Most of VectorChord’s vector types are supported by pgvector. Therefore, migrating from PGVecto.rs to VectorChord is a simple inversion of migrating from pgvector to PGVecto.rs.

Tip

We provide migration image modelzai/pgvectors-vchord for pgvecto.rs to VectorChord and vice versa.

Prerequisites

Let’s suppose that you have a table with vector data, and the extension PGVecto.rs installed. A simple example would be:

Background

High queries per second (QPS) vector search is essential for real-time applications such as recommendation engines, image recognition, and natural language processing. These applications demand rapid, efficient searches to deliver immediate results, which is critical for maintaining user engagement and operational effectiveness. By leveraging PostgreSQL for vector search, you not only benefit from its mature, robust relational capabilities and advanced indexing but also avoid the overhead of managing a separate, specialized vector database. This unified approach simplifies integration and reduces system complexity while still meeting the performance needs of modern applications.

If you want to use vectorchord in PostgreSQL which is running in Kubernetes, we provide a tutorial to help you. In this tutorial, we will use CloudNative-PG to deploy PostgreSQL cluster in Kubernetes.

Requirements

Name	Version
helm	>= 2.4.1
kubectl	>= 1.14
Kubernetes	>= 1.24.0
Kubernetes (Image Volume Extensions)	>= 1.31.0

Install CloudNative-PG

We use CloudNative-PG (cnpg) to deploy PostgreSQL cluster in Kubernetes. You can install it by helm.
