An AnalyticDB for PostgreSQL connection allows you to read data from and write data to AnalyticDB for PostgreSQL by using AnalyticDB for PostgreSQL Reader and Writer. You can configure sync nodes for AnalyticDB for PostgreSQL by using the codeless user interface (UI) or code editor.

Background information

Workspaces in standard mode support the connection isolation feature. You can add connections for the development and production environments separately and isolate the connections to protect your data security. For more information, see Connection isolation.

Procedure

  1. Go to the Data Source page.
    1. Log on to the DataWorks console.
    2. In the left-side navigation pane, click Workspaces.
    3. In the top navigation bar, select the region where your workspace resides. Find your workspace and click Data Integration in the Actions column.
    4. On the page that appears, click Connection in the left-side navigation pane. The Data Source page appears.
  2. On the Data Source page, click New data source in the upper-right corner.
  3. In the Add data source dialog box, click AnalyticDB for PostgreSQL in the Relational Database section.
  4. In the Add AnalyticDB for PostgreSQL data source dialog box, set the parameters as required.
    You can set the Data source type parameter to Alibaba Cloud Database (AnalyticDB) or Connection string mode for an AnalyticDB for PostgreSQL connection.
    • The following table describes the parameters that are displayed after you set the Data source type parameter to Alibaba Cloud Database (AnalyticDB).Add AnalyticDB for PostgreSQL data source dialog box
      Parameter Description
      Data source type The type of the connection. Set this parameter to Alibaba Cloud Database (AnalyticDB).
      Data Source Name The name of the connection. The name can contain letters, digits, and underscores (_), and must start with a letter.
      Description The description of the connection. The description can be up to 80 characters in length.
      Applicable environment The environment in which the connection is used. Valid values: Development and Production.
      Note This parameter is displayed only when the workspace is in standard mode.
      Instance ID The ID of the AnalyticDB for PostgreSQL instance. You can view the ID in the AnalyticDB for PostgreSQL console.
      Master account ID The ID of the Alibaba Cloud account that is used to purchase the AnalyticDB for PostgreSQL instance. You can view your account ID on the Security Settings page after you log on to the Alibaba Cloud Management Console with your Alibaba Cloud account.
      Database name The name of the AnalyticDB for PostgreSQL database.
      User name The username that you can use to connect to the database.
      Password The password that you can use to connect to the database.

      Parameter Description
      Data source type The type of the connection. Set this parameter to Connection string mode.
      Data Source Name The name of the connection. The name can contain letters, digits, and underscores (_), and must start with a letter.
      Description The description of the connection. The description can be up to 80 characters in length.
      Applicable environment The environment in which the connection is used. Valid values: Development and Production.
      Note This parameter is displayed only when the workspace is in standard mode.
      JDBC URL The Java Database Connectivity (JDBC) URL of the database, in the format of jdbc:postgresql://ServerIP:Port/Database.
      User name The username that you can use to connect to the database.
      Password The password that you can use to connect to the database.
  5. On the Data Integration tab, click Test connectivity in the Operation column of each resource group.
    A sync node uses only one resource group. To ensure that your sync nodes can be properly run, you must test the connectivity of all the resource groups for Data Integration on which your sync nodes will be run. If you need to test the connectivity of multiple resource groups for Data Integration at a time, select the resource groups and click Batch test connectivity. For more information, see Test data store connectivity.
  6. After the connection passes the connectivity test, click Complete.
