Scenarios

This document describes the operation steps and relevant configurations for creating an Elastic MapReduce (EMR) Serverless TCBase instance via the EMR console.

Preparations

1. The service role EMR_QCSRole has been authorized for the EMR service.
2. The user has the necessary permissions to create instances.

Operation Steps

Log in to the EMR Serverless TCBase console, click Create Instance on the instance list page, and complete the relevant configurations on the purchase page. When the instance status in the list shows Running, it indicates the instance has been successfully created.
Configuration Item
Description
Region
The physical data center where the instance is deployed. Each region is an independent data center, and the private networks of cloud services are not interconnected across different regions.
Note: The region cannot be changed after the instance is created. Please choose carefully. For supported regions available for purchase, see Billing Overview.
Instance Name
Set an instance name to distinguish between instances for different purposes.
Billing Mode
Supports pay-as-you-go and yearly/monthly subscription billing modes.
Instance Network
Select a virtual private cloud (VPC) in the corresponding region. If none exists, click Create VPC to create one.
Availability Zone and Subnet
Select the availability zone and subnet for instance deployment.
Note: The availability zone cannot be changed after the instance is created. Please choose carefully.
Public Network Access Settings
Used for accessing the TCBase WebUI via the public network and supports public network LB access.
Security Group
Security groups feature firewall capabilities to configure network access controls for Cloud Virtual Machines (CVMs). If the number of security groups has reached the upper limit and new ones cannot be created, you can delete unused security groups.
Computing Unit Architecture
Select the computing unit architecture. The default is primary/replica mode.
Instance Specifications
Select the appropriate instance specifications.
Storage Type
Select the storage type. Standard cloud storage and performance cloud storage are supported.
Storage Space
The storage space per node is 100 GB by default and can be adjusted in multiples of 100 GB.
User Information
Set the username and password for TCBase WebUI and database login. You can modify the password in the console after the instance is created.
Tag
Tencent Cloud tags can be used to distinguish between different instance uses or for cost allocation by tag.
Purchase Duration
Select the duration for purchasing a monthly subscription instance.
Auto-Renewal
Optional. The system will check daily whether the available balance in the user account is sufficient 7 days before the cluster expires and renew the cluster resources with automatic renewal enabled. For yearly/monthly subscription clusters, automatic renewal is selected by default, and users can manually deselect it.
