List collections

Prerequisites

Before you begin, make sure you have:

• Created a cluster

• Obtained an API key

• Installed the latest DashVector SDK

API signature

// DashVectorClient
public Response<List<String>> list();

The list() method takes no parameters and returns a Response<List<String>> containing the names of all collections in the cluster.

Example

Replace the placeholders before running the code:

import com.aliyun.dashvector.DashVectorClient;
import com.aliyun.dashvector.DashVectorCollection;
import com.aliyun.dashvector.common.DashVectorException;

public class Main {
    public static void main(String[] args) throws DashVectorException {
        // Initialize the client
        DashVectorClient client = new DashVectorClient("<your-api-key>", "<your-cluster-endpoint>");

        // List all collections
        Response<List<String>> response = client.list();

        System.out.println(response);
    }
}

Expected output:

{
    "code": 0,
    "message": "",
    "requestId": "5de1a75e-2996-4496-a284-9b958dfdad53",
    "output": [
        "simple",
        "quickstart"
    ]
}
