You can create an AnalyticDB for MySQL node in the DataWorks console to build an online extract, transform, and load (ETL) process.
Note You can run AnalyticDB for MySQL nodes only on exclusive resource groups for scheduling. For more information, see Add and use exclusive resource groups for scheduling.
- Go to the DataStudio page.
- Log on to the DataWorks console.
- In the left-side navigation pane, click Workspaces.
- In the top navigation bar, select the region where your workspace resides, find the workspace, and then click Data Analytics in the Actions column.
- Move the pointer over the icon and choose .Alternatively, you can click the required workflow, right-click UserDefined, and then choose .
- In the Create Node dialog box, set the Node Name and Location parameters.Note The node name must be 1 to 128 characters in length and can contain letters, digits, underscores (_), and periods (.).
- Click Commit.
- Configure the AnalyticDB for MySQL node.
- Select a connection.Select a connection for the node. If you cannot find the required connection in the drop-down list, click Add Connection and create a connection on the Data Source page. For more information, see Supported data stores and plug-ins.
- Write the SQL statements of the node.After you select a connection, write SQL statements based on the syntax that is supported by AnalyticDB for MySQL. You can write data manipulation language (DML) or data definition language (DDL) statements.
- Click the icon in the toolbar to save the SQL statements to the server.
- Click the icon in the toolbar to execute the SQL statements you have saved.When you run the node for the first time, the Parameters dialog box appears. You must select a resource group for running the node from the Scheduling Resource Group drop-down list, set other parameters as required, and then click Confirm.When you run the node later, the system uses the resource group and parameter settings that you specify for the first running of the node. If you need to change the resource group or modify the parameter settings, click the icon in the toolbar.Note To access a data store in a virtual private cloud (VPC), a node must be run on an exclusive resource group for scheduling. In this example, you must select an exclusive resource group for scheduling that is connected to the AnalyticDB for PostgreSQL instance.
- Select a connection.
- Click the Properties tab in the right-side navigation pane and set the scheduling properties for the node.
For more information, see Basic properties.You must select an exclusive resource group for scheduling that is connected to the specified AnalyticDB for MySQL data store to periodically run the node.
- Save and commit the node.Notice You must set the Rerun and Parent Nodes parameters before you can commit the node.
In a workspace in standard mode, you must click Deploy in the upper-right corner after you commit the node. For more information, see Deploy a node.
- Click the icon in the toolbar to save the node.
- Click the icon in the toolbar.
- In the Commit Node dialog box, enter your comments in the Change description field.
