Connect to Cluster

This article offers a systematic guide on connecting to a cluster.

Before you start

Ensure the following prerequisites are met before proceeding:

• You have activated your cloud. For details, see Activate Your Cloud.

• You have created a cluster. For details, see Create Cluster.

• You have installed a Milvus SDK applicable to your use case. For details, see Install SDKs.

📘Notes

For those leaning towards the utilization of RESTful APIs over SDKs, it's important to understand that a continuous connection cannot be established. This is attributed to the HTTP protocol's unidirectional communication mode.

Connect to a cluster

Once your cluster is operational, connect to it utilizing its public endpoint and an authentication token. This token can be a cluster credential that consists of a username and password pair.

Python

# Connect using a MilvusClient object
from pymilvus import MilvusClient
CLUSTER_ENDPOINT="YOUR_CLUSTER_ENDPOINT" # Set your cluster endpoint
TOKEN="YOUR_CLUSTER_TOKEN" # Set your token

# Initialize a MilvusClient instance
# Replace uri and token with your own
client = MilvusClient(
    uri=CLUSTER_ENDPOINT, # Cluster endpoint obtained from the console
    token=TOKEN # a colon-separated cluster username and password
)

Java

import io.milvus.v2.client.MilvusClientV2;
import io.milvus.v2.client.ConnectConfig;

String CLUSTER_ENDPOINT = "YOUR_CLUSTER_ENDPOINT";
String TOKEN = "YOUR_CLUSTER_TOKEN";

// 1. Connect to Milvus server
ConnectConfig connectConfig = ConnectConfig.builder()
    .uri(CLUSTER_ENDPOINT)
    .token(TOKEN)
    .build();

MilvusClientV2 client = new MilvusClientV2(connectConfig);

NodeJS

const { MilvusClient, DataType, sleep } = require("@zilliz/milvus2-sdk-node")

const address = "YOUR_CLUSTER_ENDPOINT"
const token = "YOUR_CLUSTER_TOKEN"

// 1. Connect to the cluster
const client = new MilvusClient({address, token})
