Menghubungkan ke Server Milvus

Topik ini menjelaskan cara membuat koneksi klien ke server Milvus dan mengonfigurasi opsi koneksi umum.

Prasyarat

• SDK bahasa Anda telah terinstal. Untuk detailnya, lihat Python SDK, Java SDK, Go SDK, atau Nodejs SDK.

• Alamat server Milvus (untuk default lokal: http://localhost:19530, port proxy 19530).

• Jika autentikasi diaktifkan, berikan token atau nama pengguna + kata sandi. Token dapat berupa username:password (misalnya, root:Milvus). Lihat Mengautentikasi Akses Pengguna dan Membuat Pengguna & Peran untuk detailnya.

Hubungkan dengan URI (autentikasi dinonaktifkan)

Gunakan alamat server Milvus (misal: http://localhost:19530) untuk membuat koneksi.

from pymilvus import MilvusClient

client = MilvusClient("http://localhost:19530")

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

ConnectConfig config = ConnectConfig.builder()
        .uri("http://localhost:19530")
        .build();
client = new MilvusClientV2(config);

import { MilvusClient } from '@zilliz/milvus2-sdk-node';

const client = new MilvusClient({
   address: 'http://localhost:19530'
});

import "github.com/milvus-io/milvus/client/v2/milvusclient"

c, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
    Address: "localhost:19530",
})

# The RESTful API is stateless, so there is no persistent connection.
# Each request hits the server directly; the /collections/list endpoint
# doubles as a health check when you need to verify reachability.
export HOST="localhost:19530"

curl -X POST "http://${HOST}/v2/vectordb/collections/list" \
    -H "Content-Type: application/json" \
    -H "Request-Timeout: 10" \
    -d '{}'

Menghubungkan dengan kredensial (autentikasi diaktifkan)

Sediakan token dalam bentuk "username:password" atau pisahkan user dan password. Admin bawaan default adalah root:Milvus (ubah ini untuk produksi).

from pymilvus import MilvusClient

# Token form
client = MilvusClient(
    uri="http://localhost:19530",
    token="root:Milvus",
)

# Or explicit user/password
client = MilvusClient(
    uri="http://localhost:19530",
    user="root",
    password="Milvus",
)

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

ConnectConfig config = ConnectConfig.builder()
        .uri("http://localhost:19530")
        .username("root")
        .password("Milvus")
        .build();
client = new MilvusClientV2(config);

import { MilvusClient } from '@zilliz/milvus2-sdk-node';

const client = new MilvusClient({
   address: 'http://localhost:19530',
   username: 'root',
   password: 'Milvus'
});

import "github.com/milvus-io/milvus/client/v2/milvusclient"

c, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
    Address: "localhost:19530",
    Username: "root",
    Password: "Milvus",
})

export HOST="localhost:19530"
export TOKEN="root:Milvus"

curl -X POST "http://${HOST}/v2/vectordb/collections/list" \
    -H "Authorization: Bearer ${TOKEN}" \
    -H "Content-Type: application/json" \
    -H "Request-Timeout: 10" \
    -d '{}'

Mengonfigurasi batas waktu

Tetapkan batas waktu default pada koneksi klien:

from pymilvus import MilvusClient

client = MilvusClient(uri="http://localhost:19530", timeout=1000) # If not set, the timeout defaults to 10s

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

ConnectConfig config = ConnectConfig.builder()
        .uri("http://localhost:19530")
        .rpcDeadlineMs(1000)
        .build();
client = new MilvusClientV2(config);

import { MilvusClient } from '@zilliz/milvus2-sdk-node';

const client = new MilvusClient({
   address: 'http://localhost:19530',
   username: 'root',
   password: 'Milvus',
   timeout: 1000 // ms
});
// await client.listCollections({ timeout: 2000})

import "github.com/milvus-io/milvus/client/v2/milvusclient"

ctx, cancel := context.WithTimeout(context.Background(), time.Second)
defer cancel()
c, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
    Address: "localhost:19530",
})

export HOST="localhost:19530"
export TOKEN="root:Milvus"

# Request-Timeout is applied per-request (unit: seconds). --max-time
# caps the total curl wall-clock so the client gives up even if the
# server never responds.
curl -X POST "http://${HOST}/v2/vectordb/collections/list" \
    -H "Authorization: Bearer ${TOKEN}" \
    -H "Content-Type: application/json" \
    -H "Request-Timeout: 10" \
    --max-time 7 \
    -d '{}'

Menghubungkan ke basis data tertentu

Pilih basis data target selama konstruksi dengan db_name. Anda juga dapat mengganti nanti menggunakan using_database().

from pymilvus import MilvusClient

# Set the database when creating the client
client = MilvusClient(
    uri="http://localhost:19530",
    token="root:Milvus",
    db_name="analytics",
)

# (Optional) Switch the active database later
# client.using_database("reports")

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

ConnectConfig config = ConnectConfig.builder()
        .uri("http://localhost:19530")
        .username("root")
        .password("Milvus")
        .dbName("analytics")
        .build();
client = new MilvusClientV2(config);

import { MilvusClient } from '@zilliz/milvus2-sdk-node';

const client = new MilvusClient({
   address: 'http://localhost:19530',
   username: 'root',
   password: 'Milvus',
   database: 'analytics'
});
// (Optional) Switch the active database later
// await milvusClient.useDatabase({
//   db_name: 'reports',
//});

import "github.com/milvus-io/milvus/client/v2/milvusclient"

c, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
    Address: "localhost:19530",
    DBName:  "analytics",
    APIKey:  "root:Milvus",
})
// (Optional) switch the active database later with:
err = c.UseDatabase(ctx, milvusclient.NewUseDatabaseOption("reports"))

export HOST="localhost:19530"
export TOKEN="root:Milvus"

# Target a specific database by setting "dbName" in the request body.
# The RESTful API is stateless, so include "dbName" on every request
# that should run against a non-default database.
curl -X POST "http://${HOST}/v2/vectordb/collections/list" \
    -H "Authorization: Bearer ${TOKEN}" \
    -H "Content-Type: application/json" \
    -H "Request-Timeout: 10" \
    -d '{
      "dbName": "analytics"
    }'
