### Apache Airflow version Other Airflow 2 version (please specify below) ### What happened I'm a beginnier in Aiflow and I would like to know why my tasks that just print hello world in a single task is stuck on "scheduled" status. I'm running 50 in the same time, with parallelism=0 in the config and max_ative_runs = 50 and concurrency 50 with 9 workers and 1 scheduler. Can you tell me please what could I do to improve it, it is too slow. ### What you think should happen instead I would like to run all the 50 tasks in the same second. ### How to reproduce Airflow 2.6.3 Kubernetes Airflow cfg -> parallelism = 0 9 workers 1 scheduler A dag with 1 taskapi to print hello world with max_active_runs = 50, concurrency = 50. ### Operating System linux ### Versions of Apache Airflow Providers _No response_ ### Deployment Official Apache Airflow Helm Chart ### Deployment details _No response_ ### Anything else _No response_ ### Are you willing to submit 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.
