    AnalyticDB for MySQL:Create a Data Lakehouse Edition cluster

    Last Updated:Mar 18, 2024

    This topic describes how to create a Data Lakehouse Edition (V3.0) cluster in the AnalyticDB for MySQL console.

    Create a Data Lakehouse Edition (V3.0) cluster

    1. Log on to the AnalyticDB for MySQL console. In the upper-right corner of the console, click Buy Cluster.

    2. Select an option for the Product Type parameter.

      • Pay-as-you-go: You are charged on an hourly basis for the resources that you use. This billing method is suitable for short-term usage. To reduce costs, you can release pay-as-you-go clusters when they are no longer needed.

      • Subscription: You must pay an upfront subscription fee when you create subscription clusters. For long-term usage, this billing method is more cost-effective than the pay-as-you-go billing method. You are charged lower prices for longer subscription periods.

    3. Configure the parameters that are described in the following table and click Buy Now in the lower-right corner of the page.

      Parameter

      Description

      Version

      The edition and version of the cluster. Select Data Lakehouse Edition (V3.0).

      Region

      The region where you want to create the cluster. After a cluster is created, you cannot change the region of the cluster. To maximize the cluster access speed, we recommend that you select a region that is geographically closest to your business.

      Zone

      The zone where you want to create the cluster. Each zone is an independent physical location within a region. Zones in the same region do not have substantial differences.

      Service-linked Role

      The AliyunServiceRoleForAnalyticDBForMySQL role that allows AnalyticDB for MySQL to create cluster-related resources.

      VPC

      vSwitch

      • If you have created a virtual private cloud (VPC) that meets your business requirements, select the VPC. For example, if you have created an ECS instance in a VPC that meets your business requirements, select the VPC.

      • Otherwise, use the default VPC and vSwitch. For more information, see Default VPCs and default vSwitches.

      • If the default VPC and vSwitch cannot meet your business requirements, you can create your own VPC and vSwitch. For more information, see Create and manage a VPC.

      Important

      If you use other Alibaba Cloud services such as ECS and ApsaraDB RDS, make sure that your AnalyticDB for MySQL cluster resides in the same VPC as your ECS and ApsaraDB RDS instances. If your cluster and instances reside in different VPCs, your cluster cannot communicate with your instances over an internal network to achieve optimal performance.

      Reserved Computing Resources

      The reserved computing resources of the cluster. You can use reserved computing resources to compute data. The increase in the computing resources can accelerate data queries.

      • If you require AnalyticDB for MySQL internal tables, the amount of reserved computing resources must be greater than 0 AnalyticDB compute units (ACUs).

      • If the amount of reserved computing resources is 0 ACUs, you can use only external tables.

        If you set the Reserved Computing Resources parameter to 0 ACUs when you create a cluster, you can purchase reserved computing resources by scaling up the cluster. For more information, see Scale a Data Lakehouse Edition cluster.

      Default Allocation Behavior

      Specifies whether to allocate all reserved computing resources to the user_default resource group. After you create a cluster, you can modify the amount of reserved computing resources for the user_default resource group on the Resource Management page. Valid values:

      • Yes: allocates all reserved computing resources to the user_default resource group. You can use the user_default resource group to create tables, write data, and query data.

      • No: does not allocate reserved computing resources to the user_default resource group. You cannot use the resource group to create tables, write data, or query data. You must allocate resources to the resource group or create another resource group.

      Reserved Storage Resources

      The reserved storage resources of the cluster. You can use reserved storage resources to store hot data. A set of reserved storage resources is equal to 24 ACUs and can store up to 8 TB of hot data.

      Important

      • If you set the Reserved Computing Resources parameter to 0 ACUs, you must set the Reserved Storage Resources parameter to 0 ACUs.

      • If you cannot determine the amount of required reserved storage resources when you create a cluster, you can set the Reserved Storage Resources parameter to 0 ACUs, and then purchase reserved storage resources based on your business requirements by scaling up the cluster. For more information, see Scale a Data Lakehouse Edition cluster.

      • You are billed for hot data storage based on the actual storage space that is occupied. For more information, see Billable items of Data Lakehouse Edition (V3.0).

      Version Upgrade Policy

      The policy that is used to upgrade the cluster version. The cluster is automatically upgraded to the latest version within a specified maintenance window. The default maintenance window is from 12:00 to 13:00. After you create a cluster, you can modify the maintenance window for the cluster. For more information, see Configure a maintenance window.

      Note

      • After you create a cluster, you can purchase ACU-hour plans that contain a specific number of ACU-hours at lower costs to offset the amount of pay-as-you-go ACU resources. For more information, see ACU-hour plans.

      • You can purchase storage plans that contain a specific amount of storage resources at lower costs to offset the amount of pay-as-you-go hot and cold data storage. For more information, see Storage plans.
