Drop Collection

You can drop a collection if it is no longer needed.

Examples

The following code snippets assume that you have a collection named my_collection.

from pymilvus import MilvusClient

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

client.drop_collection(
    collection_name="my_collection"
)

import io.milvus.v2.service.collection.request.DropCollectionReq;
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);

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

client.dropCollection(dropQuickSetupParam);

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

const address = "http://localhost:19530";
const token = "root:Milvus";
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
//
