Memodifikasi Koleksi

Anda dapat mengganti nama koleksi atau mengubah pengaturannya. Halaman ini berfokus pada cara mengubah koleksi.

Mengganti Nama Koleksi

Anda dapat mengganti nama koleksi sebagai berikut.

from pymilvus import MilvusClient

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

client.rename_collection(
    old_name="my_collection",
    new_name="my_new_collection"
)

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

String CLUSTER_ENDPOINT = "http://localhost:19530";
String TOKEN = "root:Milvus";

// 1. Connect to Milvus server
ConnectConfig connectConfig = ConnectConfig.builder()
    .uri(CLUSTER_ENDPOINT)
    .token(TOKEN)
    .build();
    
MilvusClientV2 client = new MilvusClientV2(connectConfig);

RenameCollectionReq renameCollectionReq = RenameCollectionReq.builder()
        .collectionName("my_collection")
        .newCollectionName("my_new_collection")
        .build();

client.renameCollection(renameCollectionReq);

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

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

const res = await client.renameCollection({
    oldName: "my_collection",
    newName: "my_new_collection"
});

import (
    "context"
    "fmt"
    "log"

    "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)

err = cli.RenameCollection(ctx, client.NewRenameCollectionOption("my_collection", "my_new_collection"))
if err != nil {
    // handle error
}

export CLUSTER_ENDPOINT="http://localhost:19530"
export TOKEN="root:Milvus"

curl --request POST \
--url "${CLUSTER_ENDPOINT}/v2/vectordb/collections/rename" \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
-d '{
    "collectionName": "my_collection",
    "newCollectionName": "my_new_collection"
}'

Mengatur TTL Koleksi

Untuk menghapus data kedaluwarsa secara otomatis dari koleksi Milvus, Anda dapat mengatur Time-To-Live (TTL) koleksi dalam hitungan detik. Setelah TTL berakhir, Milvus akan menandai data sebagai data kedaluwarsa dan menjadwalkannya untuk dihapus secara asinkron. Akibatnya, data mungkin masih muncul di hasil pencarian sampai proses penghapusan selesai sepenuhnya.

Cuplikan kode berikut ini menunjukkan cara mengubah TTL koleksi.

from pymilvus import MilvusClient

client.alter_collection_properties(
  collection_name="collection_name",
  properties = {"collection.ttl.seconds": 500}
)

import io.milvus.v2.service.collection.request.AlterCollectionReq;
import java.util.HashMap;
import java.util.Map;

Map<String, String> properties = new HashMap<>();
properties.put("collection.ttl.seconds", "60");

AlterCollectionReq alterCollectionReq = AlterCollectionReq.builder()
        .collectionName("my_collection")
        .properties(properties)
        .build();

client.alterCollection(alterCollectionReq);

res = await client.alterCollection({
    collection_name: "my_collection",
    properties: {
        "collection.ttl.seconds": 60
    }
})

import (
    "context"
    "fmt"
    "log"

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


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)

err = cli.AlterCollection(ctx, client.NewAlterCollectionOption("my_collection").WithProperty(common.CollectionTTLConfigKey, 60))
if err != nil {
    // handle error
}
