コレクションの削除

不要になったコレクションは削除できます。

例

以下のコードスニペットは、my_collection という名前のコレクションがあることを前提としています。

python
from pymilvus import MilvusClient

client = MilvusClient(
    uri="YOUR_CLUSTER_ENDPOINT",
    token="YOUR_CLUSTER_TOKEN"
)

client.drop_collection(
    collection_name="my_collection"
)

java
import io.milvus.v2.service.collection.request.DropCollectionReq;
import io.milvus.v2.client.ConnectConfig;
import io.milvus.v2.client.MilvusClientV2;

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);

DropCollectionReq dropQuickSetupParam = DropCollectionReq.builder()
        .collectionName("my_collection")
        .build();

client.dropCollection(dropQuickSetupParam);

javascript
import { MilvusClient, DataType } from "@zilliz/milvus2-sdk-node";

const address = "YOUR_CLUSTER_ENDPOINT";
const token = "YOUR_CLUSTER_TOKEN";
const client = new MilvusClient({address, token});

// 10. Drop the collection
res = await client.dropCollection({
    collection_name: "my_collection"
})

console.log(res.error_code)

// Output
// 
// Success
// 

go
import (
    "context"
    "fmt"
    "log"

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

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

milvusAddr := "YOUR_CLUSTER_ENDPOINT"
token := "YOUR_CLUSTER_TOKEN"

client, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
    Address: milvusAddr,
    APIKey:  token,
})
if err != nil {
    fmt.Println(err.Error())
    // handle error
}
defer client.Close(ctx)

err = client.DropCollection(ctx, milvusclient.NewDropCollectionOption("my_collection"))
if err != nil {
    fmt.Println(err.Error())
    // handle error
}

bash

c++

auto client = milvus::MilvusClientV2::Create();

milvus::ConnectParam connect_param{"YOUR_CLUSTER_ENDPOINT", "YOUR_CLUSTER_TOKEN"};
auto status = client->Connect(connect_param);
if (!status.IsOk()) {
    std::cout << status.Message() << std::endl;
}

status = client->DropCollection(milvus::DropCollectionRequest()
                                    .WithCollectionName("my_collection"));
if (!status.IsOk()) {
