Drop a collection

This topic describes how to drop a collection and the data within.

Dropping a collection irreversibly deletes all data within it.

When interacting with Milvus using Python code, you have the flexibility to choose between PyMilvus and MilvusClient (new). For more information, refer to Python SDK.

Python Java GO Node.js Curl 
from pymilvus import utility
utility.drop_collection("book")

await milvusClient.dropCollection({ collection_name: "book" });

err = milvusClient.DropCollection(
  context.Background(), // ctx
  "book",               // CollectionName
)
if err != nil {
    log.Fatal("fail to drop collection:", err.Error())
}

milvusClient.dropCollection(
  DropCollectionParam.newBuilder()
    .withCollectionName("book")
    .build()
);

delete collection -c book

curl -X 'DELETE' \
  '${MILVUS_HOST}:${MILVUS_PORT}/v1/vector/collections/drop' \
  -H 'Authorization: Bearer ${TOKEN}' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
    "collection_name": "book"
  }'

    "data": {}
