    Dataphin:Create a MaxCompute data source

    Last Updated:Jan 13, 2026

    Create a MaxCompute data source to enable Dataphin to read data from or write data to MaxCompute. This topic describes how to create a MaxCompute data source.

    Background information

    MaxCompute is a big data computing service from Alibaba Cloud. It is an enterprise-level cloud data warehouse provided as Software as a Service (SaaS) for data analytics scenarios. It provides a fast and fully managed online data warehouse service that uses a serverless architecture. This eliminates the limitations of traditional data platforms in terms of resource extensibility and elasticity and minimizes your operations and maintenance (O&M) costs. This enables you to analyze and process large amounts of data in a cost-effective and efficient way.

    Limits

    MaxCompute data sources do not support access to external MaxCompute projects. For more information, see MaxCompute project overview.

    Permission description

    Only super administrators, data source administrators, domain architects, project administrators, and custom global roles with the Create Data Source permission can create data sources.

    Procedure

    1. On the Dataphin home page, in the top menu bar, click Management Hub > Data Source Management.

    2. On the Data Source page, click +Create Data Source.

    3. On the Create Data Source page, in the Big Data Storage section, select MaxCompute.

      If you have recently used MaxCompute, you can also select MaxCompute from the Recently Used section. You can also enter MaxCompute in the search box to perform a quick search.

    4. On the Create MaxCompute Data Source page, configure the connection parameters.

      1. Configure the basic information for the data source.

        Parameter

        Description

        Data Source Name

        Enter a name for the data source. The name must meet the following requirements:

        • It can contain only Chinese characters, uppercase and lowercase letters, digits, underscores (_), and hyphens (-).

        • The maximum length is 64 characters.

        Data Source Code

        After you configure the data source code, you can directly access Dataphin data source tables in Flink_SQL tasks or using the Dataphin Java Database Connectivity (JDBC) client. Use the format data_source_code.table_name or data_source_code.schema.table_name for quick access. To automatically switch data sources based on the task execution environment, use the variable format ${data_source_code}.table or ${data_source_code}.schema.table. For more information, see Develop Dataphin data source tables.

        Important

        • The data source code cannot be modified after it is configured.

        • You can preview data on the object details page in the asset directory and asset checklist only after the data source code is configured.

        • In Flink SQL, only MySQL, Hologres, MaxCompute, Oracle, StarRocks, Hive, SelectDB, and GaussDB data warehouse service (DWS) data sources are currently supported.

        Data Source Description

        Enter a brief description of the data source. The description cannot exceed 128 characters.

        Data Source Configuration

        Select the data source to configure:

        • If your business data source distinguishes between production and development data sources, select Production + Development Data Source.

        • If your business data source does not distinguish between production and development data sources, select Production Data Source.

        Tag

        You can categorize and tag data sources based on tags. For information about how to create tags, see Manage data source tags.

      2. Configure the connection parameters between the data source and Dataphin.

        If you select Production + Development Data Source, configure the connection information for the Production And Development Data Sources. If you select Production Data Source, configure the connection information for only the Production Data Source.

        Note

        Typically, production and development data sources are configured separately to isolate the development environment from the production environment. This prevents development activities from affecting the production data source. However, Dataphin also supports configuring them as the same data source with identical parameter values.

        Parameter

        Description

        Endpoint

        The endpoint of MaxCompute. Select the endpoint based on your network environment and connection method.

        For information about how to obtain the endpoint, see Endpoint.

        Access ID, Access Key

        The AccessKey ID and AccessKey secret of the account where the MaxCompute data source is located.

        For information about how to obtain them, see Obtain an AccessKey.

        Note

        This parameter can be configured only when you set Authentication Type to AccessKey Authentication.

        Project Name

        This is the MaxCompute project name, not the DataWorks workspace name.

        You can log on to the MaxCompute console, switch to the appropriate region in the upper-left corner, and then view the specific MaxCompute Project Name on the Project Management tab.

    5. Select a Default Resource Group. This resource group is used to run tasks related to the current data source, such as database SQL queries, offline full database migrations, and data previews.

    6. Click Test Connection, or click OK to save the configuration and create the MaxCompute data source.

      Click Test Connection to verify that the data source can connect to Dataphin. If you click OK, the system automatically tests the connections for all selected clusters. The data source can still be created even if all connection tests fail.
