Research direction
Study Airflow's catchup mechanism (https://airflow.apache.org/docs/apache airflow/stable/dag run.html#catchup). Analyze DolphinScheduler's workflow scheduling code, particularly the scheduler and workflow instance creation logic. Identify where catchup would fit, considering time based scheduling. Review database schema for workflow instances to support backfilling runs.
