A SelectDB or Doris compute source attaches to a Dataphin project to provide computing resources for processing compute tasks. If the compute engine of the Dataphin system is set to SelectDB or Doris, the project can use features such as compute tasks, ad hoc queries, and scripts only after you add a SelectDB or Doris compute source to the project. This topic describes how to create a SelectDB or Doris compute source.
Prerequisites
The compute engine of Dataphin is set to SelectDB or Doris. For more information, see Initialize the metadata warehouse using SelectDB or Doris as the metadata warehouse engine.
A SelectDB or Doris cluster is created. For more information, see Create and manage a SelectDB or Doris cluster.
Procedure
In the top menu bar of the Dataphin homepage, choose Planning > Compute Source.
On the Compute Source page, click New Compute Source and select SelectDB Compute Source or Doris Compute Source.
In the Create SelectDB Compute Source or Create Doris Compute Source dialog box, configure the required parameters.
Parameter
Description
Basic Information
Compute Type
Select SelectDB or Doris.
Compute Source Name
The name can contain Chinese characters, letters, digits, underscores (_), and hyphens (-) and can be up to 64 characters in length.
Configuration Method
Currently, only Reference Specified Cluster is supported. You can enter keywords to search for a cluster. After you select a cluster, you can click View to go to the View SelectDB Cluster or View Doris Cluster page to view the cluster information.
Description (optional)
Enter a brief description of the compute source. The description can be up to 128 characters in length.
Compute Configuration
JDBC URL
The system automatically obtains this parameter from the selected SelectDB or Doris cluster. You cannot modify this parameter.
Catalog
The system automatically obtains this parameter from the selected SelectDB or Doris cluster. If this parameter is empty in the cluster configuration, it is also empty here. You cannot modify this parameter.
Database
Select a database. The available options include all databases in the selected cluster.
Authentication User
You can select Same As Cluster or Custom. The default value is Same as Cluster. If you select Custom, you need to enter the Username and Password for authentication. To ensure that tasks can be executed properly, make sure that the user has the required database permissions.
Node Resource Group
You can select Do Not Specify Resource Group or Specify Resource Group. The default value is Do Not Specify Resource Group. If you select Specify Resource Group, you need to set resource groups with different priorities.
Click Submit.
After you create a SelectDB or Doris compute source, you can attach it to a project. For more information, see Create a general project.
