[GitHub] [airflow] enriqueayala opened a new issue #18583: max_active_runs ignored with TriggerDagRunOperator
enriqueayala opened a new issue #18583:
URL: https://github.com/apache/airflow/issues/18583
### Apache Airflow version
2.1.4 (latest released)
### Operating System
Ubuntu 20.04
### Versions of Apache Airflow Providers
_No response_
### Deployment
Virtualenv installation
### Deployment details
_No response_
### What happened
`max_active_runs` isn't respected when dag is triggered externally by TriggerDagRunOperator
### What you expected to happen
Limit number of concurrent runs specified by `max_active_runs` ,subsequent dag runs should allocated on new queue state
### How to reproduce
Modify example_dags\example_trigger_target_dag.py to limit `max_active_runs = 2 ` and add time.sleep for test convenience :
```
from airflow import DAG
from airflow.operators.bash import BashOperator
from airflow.operators.python import PythonOperator
from airflow.utils.dates import days_ago
def run_this_func(**context):
"""
Print the payload "message" passed to the DagRun conf attribute.
:param context: The execution context
:type context: dict
"""
import time
time.sleep(10)
print(f"Remotely received value of {context['dag_run'].conf['message']} for key=message")
with DAG(
dag_id="example_trigger_target_dag",
default_args={"owner": "airflow"},
start_date=days_ago(2),
schedule_interval=None,
max_active_runs=2,
tags=['example'],
) as dag:
run_this = PythonOperator(task_id="run_this", python_callable=run_this_func)
bash_task = BashOperator(
task_id="bash_task",
bash_command='echo "Here is the message: $message"',
env={'message': '{{ dag_run.conf["message"] if dag_run else "" }}'},
)
```
And manually trigger multiple runs of example_trigger_controller_dag :
