Manage Milvus with Attu - Vector Retrieval Service for Milvus

Attu is an open-source management tool designed for the Milvus vector database. It provides a graphical user interface (GUI) to simplify Milvus operations. Vector Retrieval Service for Milvus integrates Attu to help you efficiently manage databases, collections, indexes, and entities.

Prerequisites

You have configured network access for your instance.

Connect to Attu

You can connect to the Attu interface by using its internal or public endpoint.

In a browser, enter the endpoint. Use either access method:
- Internal endpoint: {{clusterId}}-internal.milvus.aliyuncs.com:3000
- Public endpoint: {{clusterId}}.milvus.aliyuncs.com:3000
  Note
  If your instance is configured with a public endpoint, you can also access Attu by clicking Attu Manager on the Details page in the console.
In the dialog box, enter the database, username, and password, and then click Connect.
After an instance is created, a default database and a user named root are automatically created. The password for the root user is the one you set during instance creation.

Manage databases

You can create, delete, and view databases with Attu. Ensure you have the necessary permissions to perform these operations.

Note

The default database cannot be deleted.

To create a database:

In the left navigation bar, click the icon.
On the Databases page, click + Create Database.
In the dialog box, enter a database name, and click Create.

Manage collections

A collection is similar to a table in a relational database. Attu allows you to manage collection schemas, import data, and perform other maintenance tasks. The following steps show a typical workflow.

In the left navigation bar, click the icon.
On the Collections page, click + Collection to create a new collection, such as demo.
Click Create Index to define an index for it, such as demo_idx.
Import your sample data into the demo collection.
Load the collection into memory to enable searching.

Note

To reserve memory, you can click Release to unload a collection from memory. Although the data is retained on disk, you cannot perform search or query operations on it until it is loaded again.
To permanently delete a collection and all its data, click Drop. This action cannot be undone.

Perform a vector search

After a collection is loaded into memory, you can perform vector similarity searches.

Select a loaded collection, and then click the Vector Search tab.
Enter the target vector for your similarity search and configure the search parameters.
Click Search.
To refine your results, click the icon and apply filters on scalar fields within the collection.

Manage users and roles

You can create and manage users and roles to control access to your database.

Create a user

In the left navigation bar, click the icon.
On the Users tab, click + User.
In the dialog box, set username and password, assign a role, and click Create.

Create a role

On the User and Role page, click the Roles tab.
Click + Role.
In the dialog box, set a role name, select the desired privileges, and click Create.
