Create an Aliyun EMR Serverless Spark compute source

Prerequisites

• Dataphin's Compute Engine is set to Aliyun EMR Serverless Spark.

• You have an Aliyun EMR Serverless Spark cluster. For more information, see Create and manage an Aliyun EMR Serverless Spark cluster.

Procedure

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

2. On the Compute Source page, click New Compute Source, and then select Aliyun EMR Serverless Spark Compute Source.

3. On the New Aliyun EMR Serverless Spark Compute Source page, configure the following parameters.

   Parameter		Description
   Basic information	Compute source type	Select Aliyun EMR Serverless Spark.
   	Compute source name	The name can be up to 64 characters and may include Chinese characters, letters, digits, underscores (_), and hyphens (-).
   	Configuration method	Only Reference Specified Cluster is supported. You can search for a cluster by keyword. After selecting a cluster, click View to review its details on the View Aliyun EMR Serverless Spark Cluster page.
   	Compute source description (Optional)	Enter a description for the compute source, up to 128 characters.
   Connection configuration	Workspace	The workspace is inherited from the selected cluster and cannot be modified.
   	Catalog	Select a Catalog. The dropdown list includes all Catalogs in the selected cluster.
   	Schema	Select a Schema. The dropdown list includes all Schemas in the selected Catalog.
   Gateway configuration	Default gateway for production jobs	The dropdown list contains all Gateways added to the selected cluster. It displays the following information for each Gateway: status, specifications, Spark version, Kyuubi Service Engine Version, queue name, Access Method, and the number of High Availability (HA) replicas.
   	Gateway for other jobs
   	Gateway for priority jobs	By default, this is the same as the gateway for production jobs. If you select Custom, you must also select a Gateway for each priority level.

4. Click Submit.

   Once created, you can bind the Aliyun EMR Serverless Spark compute source to a Project. For more information, see Create a general-purpose project.
