Adding Dataflow Runtime Options
Dataflow runtime options enable you control the behavior of stages when you run the dataflow. This is useful when you want to have the ability to modify the behavior of the dataflow when it runs. For example, you may want to specify a source database for a Read from DB stage when you run the dataflow, rather than using the database specified in the Read from DB stage in the dataflow.
This procedure describes how to expose options that can be set at runtime. After performing this procedure you will be able to set dataflow options at runtime using these techniques:
- For jobs, you will be able to specify runtime options using a dataflow options
property file and job executor's
-o
argument. - For services, you will be able to specify runtime options as API options.
- For services exposed as web service, you will be able to specify runtime options as parameters in the request.
- For subflows, runtime options will be inherited by the parent dataflow and exposed through one of the above means, depending on the parent dataflow type (job, service, or service exposed as a web service).
To add runtime options to a dataflow,
The dataflow is now configured to allow options to be specified at runtime.
