amit-mittal opened a new issue, #56319: URL: https://github.com/apache/airflow/issues/56319
### Description Using below `Param` with default value as today's date as mentioned in the [official doc](https://airflow.apache.org/docs/apache-airflow/stable/core-concepts/params.html#use-params-to-provide-a-trigger-ui-form) will create a new DAG version as part of every run on a different day. ``` Param(f"{datetime.date.today()}", type="string", format="date") ``` The issue gets even worse if you accidentally use `time.time()` as the default parameter. We should also add a `ruff lint` check to catch this. ### Use case/motivation - Avoid accidental version creation as `serialized_dag` table can become really heavy - Official docs recommend this, but I think either it shouldn't create a version or there should be some other best practice for dates ### Related issues A lot of versions get created for the DAG even though engineer didn't update DAG's code ### Are you willing to submit a PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
