E-MapReduce:View the instance list and details of an instance

Last Updated:Mar 26, 2026

The Instance List page is your starting point for managing EMR Serverless StarRocks instances. Use the list to check instance status at a glance, then drill into an instance's details to find connection endpoints, node specifications, and security configuration.

Prerequisites

Before you begin, ensure that you have:

View the instance list

  1. Log on to the EMR console.

  2. In the left-side navigation pane, choose EMR Serverless > StarRocks.

  3. In the top navigation bar, select a region.

The Instance List page shows all instances in the selected region. The following table describes the columns on the page.

ColumnDescription
Instance ID/NameThe ID and name of the instance.
StatusThe current status of the instance.
Billing MethodThe billing method of the instance.
Instance TypeThe instance type: storage-compute integrated or storage-compute separated.
TagTags assigned to the instance for identification and resource management.
ActionsOperations available for the instance. See the following section for details.

Actions

Connect

Connect to the instance using StarRocks Manager. For more information, see Use EMR StarRocks Manager to connect to a StarRocks instance.

Renew

Extend the subscription period of a subscription instance. For more information, see Renewal policy.

Only subscription instances support renewal. This action is unavailable for pay-as-you-go instances.

Restart

Restart the instance for maintenance tasks such as system updates or configuration changes that require a service restart to take effect.

Warning

Restarting an instance may cause a transient disconnection. Make sure your client implements a retry mechanism before initiating the restart.

Release

Release an instance you no longer need to avoid unnecessary charges.

Important

Releasing an instance permanently deletes the instance and all its resources. This action cannot be undone.

View instance details

  1. On the Instance List page, click the name of the instance.

  2. On the Instance Details tab, review the information in each section.

The following table describes the sections on the Instance Details tab.

SectionDescription
Basic InformationCore instance attributes: instance ID, instance name, creation time, zone, billing method, virtual private cloud (VPC), vSwitch, and security group ID.
Security ConfigurationSecurity settings, including network whitelists and password management.
Version InformationThe instance edition, major version, and minor version.
Manager AgentManager Agent is the agent service that StarRocks Manager uses to connect to instances. It runs on the frontend (FE) nodes by default. If your FE nodes are under high load or you need higher stability for StarRocks Manager, you can enable independent Manager Agent resources. For more information, see Manage Manager Agent.
Gateway InformationThe default gateway details: internal endpoint, network type, public endpoint, and number of FE nodes. For storage-compute separated instances, you can add independent gateways for different business scenarios. For more information, see Manage gateways.
FE DetailsFrontend (FE) node details: specifications, storage size, number of nodes, storage type, internal endpoint, public endpoint, and port number.
BE Details or CN DetailsFor storage-compute integrated instances, the BE Details section shows backend (BE) node details. For storage-compute separated instances, the CN Details section on the Warehouse tab shows compute node (CN) details—including specifications, number of nodes, and internal endpoint. For more information about compute groups, see Compute groups.
