Create a MaxCompute compute source

Procedure

1. In the top navigation bar of Dataphin, choose Planning > Compute Source.

2. On the Compute Source page, click Create Compute Source and select MaxCompute Compute Source.

3. On the Create MaxCompute Compute Source page, configure the required parameters.

   Parameter		Description
   Basic Information Of Compute Source	Compute Source Type	Select MaxCompute.
   	Endpoint	Defaults to the compute engine endpoint. Not modifiable.
   	AccessKey ID,AccessKey Secret	Enter the AccessKey ID and AccessKey Secret of an account with access to the MaxCompute project. Obtain these values from the User Management page. Important Use the AccessKey of the MaxCompute project administrator for reliable connectivity. Do not change this AccessKey after setup. Changes disrupt metadata collection.
   Compute Source Configuration	MaxCompute Project	Select or enter a MaxCompute project. The dropdown shows only projects visible to the AccessKey user. You can also enter a project name manually or create one in the MaxCompute console. Note This is the MaxCompute project name, not the DataWorks workspace name. Switch to the target region in the MaxCompute console to find the MaxCompute project name on the Project Management tab.
   	External Project	Default: No. Set to Yes for external projects. Note Integration tasks cannot read from or write to external projects. Hologres cannot accelerate queries on external projects. Table storage usage from MaxCompute metadata is unavailable for external projects. Storage health scores and storage usage are unavailable for external project resources.
   	Compute Project	Select or enter a compute project. The dropdown shows only projects visible to the AccessKey user. You can also enter a project name manually or create one in the MaxCompute console. Required when the MaxCompute project is external. Serves as the computing resource.
   	Compute Source Name	Enter a compute source name. Requirements: Supports Chinese characters, digits, letters, underscores (_), and hyphens (-). Maximum length: 64 characters.
   	Description	Enter a brief description of the compute source.

   Note

   To batch-create compute sources under different AccessKey IDs, click Create Compute Source repeatedly. Maximum: 10 at a time.

4. Click Test Connection to verify connectivity between Dataphin and the AccessKey account.

5. After the test passes, click Verify And Submit to create the compute source.
