How to execute another job after a background job?

I want to execute the following jobs:

1. Use scheduleJob to run job1 at a specific time, such as 09:25m, and
   set the parameter onComplete to function1;

2. Within function1, define func2 and call submitJobEx to submit job2
   where function2 is executed.

3. After submitJobEx, use getJobReturn to get the output of job2.

4. Continue running job3.

How can I achieve the workflow?

Defining one method within another method, such as defining function2 within function1, is not supported in DolphinDB. It is recommended to use a scheduling framework like Airflow to schedule and manage workflows. For complex workflows, an external scheduling system should be used. DolphinDB supports the Airflow plugin.
