查看收藏集

您可以获取当前连接的数据库中所有 Collections 的名称列表，并查看特定 Collections 的详细信息。

列出收藏集

下面的示例演示了如何获取当前连接的数据库中所有集合的名称列表。

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 '{}
}'

如果您已经创建了一个名为quick_setup 的 Collection，则上述示例的结果应类似于下面的内容。

["quick_setup"]

描述 Collection

您还可以获取特定 Collection 的详细信息。下面的示例假定您已经创建了名为 quick_setup 的 Collection。

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"
}'
