Aerospike Vector Search Go Client

:warning: The go client is currently in development. APIs will break in the future!

Overview

This repository contains the Go client for interacting with Aerospike Vector Search (AVS) capabilities. It is designed to provide an easy-to-use interface for performing vector searches with an Aerospike cluster.

Current Functionality

Connection to Aerospike clusters
Create, List, Drop Indexes

Installation

To install the Aerospike Vector Search Go Client, use the following command:

go get github.com/aerospike/avs-client-go

Example Usage

Here's a quick example to get you started:

package main

import (
	"context"
	"fmt"
	"log/slog"
	"os"
	"time"

	avs "github.com/aerospike/avs-client-go"
	"github.com/aerospike/avs-client-go/protos"
)

func main() {
	connectCtx, cancel := context.WithTimeout(context.Background(), time.Second*5)
	hostPort := NewHostPort("127.0.0.1", 5000)
	loadBalancer := true
	credentials := NewCredentialsFromUserPass("admin", "admin")
	logger := slog.New(slog.NewTextHandler(os.Stderr, &slog.HandlerOptions{Level: slog.LevelDebug}))

	var (
		listenerName *string
		tlsConfig *tls.Config
	)

	client, err := avs.NewClient(
		connectCtx,
		HostPortSlice{hostPort},
		listenerName,
		loadBalancer,
		credentials
		tlsConfig,
		logger,
	)
	cancel()

	if err != nil {
		logger.Error("failed to create admin client", slog.Any("error", err))
		return
	}

	logger.Info("successfully connected to server")
	defer client.Close()

	namespace := "test"
	indexName := "bookIndex"
	vectorField := "vector"
	dimensions := uint32(10)
	distanceMetric := protos.VectorDistanceMetric_MANHATTAN
	indexOpts := &IndexCreateOpts{
		Set: []string{"testset"}
	}

	err = client.IndexCreate(
		context.Background(),
		namespace,
		indexName,
		vectorField,
		dimensions,
		distanceMetric,
		indexOpts,
	)
	if err != nil {
		logger.Error("failed to create index", slog.Any("error", err))
		return
	}

	logger.Info("successfully created index")

	indexes, err := client.IndexList(context.Background(), true)
	if err != nil {
		logger.Error("failed to list indexes", slog.Any("error", err))
		return
	}

	for _, index := range indexes.GetIndices() {
		fmt.Println(index.String())
	}

	err = client.IndexDrop(context.Background(), namespace, indexName)
	if err != nil {
		logger.Error("failed to drop index", slog.Any("error", err))
		return
	}

	logger.Info("successfully dropped index")
	logger.Info("done!")
}
