vividbaek opened a new pull request, #67676:
URL: https://github.com/apache/airflow/pull/67676
Add a small documentation section to `params.rst` showing how to combine
Params, dry-run defaults, ``max_active_runs=1``, and task-level guards
(pools, execution timeouts) in a manually triggered remediation Dag.
This pattern is common in operational workflows such as backfill,
reprocessing, or data repair where incorrect user input can directly
affect external systems. The example demonstrates:
- Param schema validation for user input
- Runtime validation inside a task (e.g., date range checks)
- ``dry_run=True`` as a safe default for first-time triggers
- ``max_active_runs=1`` to prevent concurrent runs of the same Dag
- Pool and execution timeout to protect the external system
This is a documentation-only change. No runtime behavior is affected.
