Offline mode variable configuration
Variable parameter configuration assigns values to variables in computation task code so that the variables are automatically replaced with the corresponding values at runtime. Flink_SQL is used as an example.
Procedure
-
Navigate to the Development section via the top menu bar on the Dataphin home page. You will be directed to the data Development page by default.
-
Using the operation guide depicted below, select the task you wish to configure and access the Configuration panel.
-
Within the Variable Configuration section of the configuration panel, set up the task parameters.
In the Variable Configuration area, add parameters by using expressions in the code editor. Existing parameters are automatically populated. Use the Expression format:
${variable_name}to insert variables. You can also edit the parameter type and assign values in the parameter list.NoteThe variable configuration list allows for batch operations. After selecting individual or all parameters, you can perform batch modifications of parameter types by clicking
.Parameter
