컬렉션 보기

현재 연결된 데이터베이스에 있는 모든 컬렉션의 이름 목록을 확인하고 특정 컬렉션의 세부 정보를 확인할 수 있습니다.

컬렉션 목록 보기

다음 예제는 현재 연결된 데이터베이스에 있는 모든 컬렉션의 이름 목록을 조회하는 방법을 보여줍니다.

from pymilvus import MilvusClient, DataType

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

res = client.list_collections()

print(res)

import io.milvus.v2.client.ConnectConfig;
import io.milvus.v2.client.MilvusClientV2;
import io.milvus.v2.service.collection.response.ListCollectionsResp;

ConnectConfig connectConfig = ConnectConfig.builder()
        .uri("http://localhost:19530")
        .token("root:Milvus")
        .build();

MilvusClientV2 client = new MilvusClientV2(connectConfig);

ListCollectionsResp resp = client.listCollections();
System.out.println(resp.getCollectionNames());

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

const client = new MilvusClient({
    address: 'localhost:19530',
    token: 'root:Milvus'
});


const collections = await client.listCollections();
console.log(collections);

import (
    "context"
    "fmt"

    "github.com/milvus-io/milvus/client/v2"
)

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

milvusAddr := "127.0.0.1:19530"
token := "root:Milvus"

cli, err := client.New(ctx, &client.ClientConfig{
    Address: milvusAddr,
    APIKey:  token,
})
if err != nil {
    log.Fatal("failed to connect to milvus server: ", err.Error())
}

defer cli.Close(ctx)

collectionNames, err := cli.ListCollections(ctx, client.NewListCollectionOption())
if err != nil {
    // handle error
}

fmt.Println(collectionNames)

curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/collections/list" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
-d '{}
}'

이미 quick_setup 라는 이름의 컬렉션을 만든 경우 위 예제의 결과는 다음과 비슷할 것입니다.

["quick_setup"]

컬렉션 설명

특정 컬렉션의 세부 정보를 얻을 수도 있습니다. 다음 예제에서는 이미 quick_setup이라는 컬렉션을 만들었다고 가정합니다.

res = client.describe_collection(
    collection_name="quick_setup"
)

print(res)

import io.milvus.v2.service.collection.request.DescribeCollectionReq;
import io.milvus.v2.service.collection.response.DescribeCollectionResp;

DescribeCollectionReq request = DescribeCollectionReq.builder()
        .collectionName("quick_setup")
        .build();
DescribeCollectionResp resp = client.describeCollection(request);
System.out.println(resp);

const res = await client.describeCollection({
    collection_name: "quick_setup"
});

console.log(res);

import (
    "context"
    "fmt"

    "github.com/milvus-io/milvus/client/v2"
)

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

milvusAddr := "127.0.0.1:19530"
token := "root:Milvus"

cli, err := client.New(ctx, &client.ClientConfig{
    Address: milvusAddr,
    APIKey:  token,
})
if err != nil {
    log.Fatal("failed to connect to milvus server: ", err.Error())
}

defer cli.Close(ctx)

collection, err := cli.DescribeCollection(ctx, client.NewDescribeCollectionOption("quick_setup"))
if err != nil {
    // handle error
}

fmt.Println(collection)

curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/collections/describe" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
-d '{
    "collectionName": "quick_setup"
}'
