[jira] [Updated] (AIRFLOW-2965) Add CLI command to find the next
dag run.
[ https://issues.apache.org/jira/browse/AIRFLOW-2965?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
jack updated AIRFLOW-2965:
--------------------------
Description:
I have a dag with the following properties:
{code:java}
dag = DAG(
dag_id='mydag',
default_args=args,
schedule_interval='0 1 * * *',
max_active_runs=1,
catchup=False){code}
This runs great.
Last run is: 2018-08-26 01:00 (start date is 2018-08-27 01:00)
Now it's 2018-08-27 17:55 I decided to change my dag to:
{code:java}
dag = DAG(
dag_id='mydag',
default_args=args,
schedule_interval='0 23 * * *',
max_active_runs=1,
catchup=False){code}
Now, I have no idea when will be the next dag run.
Will it be today at 23:00? I can't be sure when the cycle is complete. I'm not even sure that this change will do what I wish.
I'm sure you guys are expert and you can answer this question but most of us wouldn't know.
The scheduler has the knowledge when the dag is available for running. All I'm asking is to take that knowledge and create a CLI command that I will give the dag_id and it will tell me the next date/hour which my dag will be runnable.
