Since this is a source of confusion to many new users there is an architecture change in progress AIP-39 Richer scheduler_interval which will decople between WHEN to run and WHAT interval to consider with this run. ![]() The second run will start on 10:00 this run execution_date will be 10:00 Means that the first will start on 10:00 this run execution_date will be 10:00. Today you are processing yesterday data so at the end of this day you want to start a process that will go over yesterday records.Īs a rule - NEVER use dynamic start date. This is consistent with how data pipelines usually works. Airflow execute the job at the END of the interval. The following steps show how you can change the timezone in which Amazon MWAA runs your DAGs with Pendulum.Optionally, this topic demonstrates how you can create a custom plugin to change the timezone for your environments Apache Airflow logs. In Airflow the scheduling is calculated by start_date + schedule interval. Apache Airflow schedules your directed acyclic graph (DAG) in UTC+0 by default. ![]() In cron jobs you just provide a cron expression and it schedule accordingly - This is not how it works in Airflow. You are simply confusing Airflow scheduling mechanizem with cron jobs. If I replace days_ago(0) with days_ago(1) it is behind 1 day all the time Im having a problem with an airflow server where any time I try and run a dag I get the following error: FileNotFoundError: Errno 2 No such file or directory: airflow: airflow All dags stay in in a queued state unless I set them to a running state or mark the previous task as successful. Isn't there an easy way to say "I deploy my DAG now, and I want to get it executed with this cron-syntax" (which I assume is what most people want) instead of calculating an execution time, based on start_date, schedule_interval and figuring out, how to interpret it? If I replace days_ago(0) with days_ago(1) it is behind 1 day all the time i.e it does not get run today but did run yesterday I have tried different start_dates altso start_date = datetime.datetime(2021,6,23) but it does not get executed. How do I get to execute my DAG at a specific time each day? E.g say it's now 9:30 (AM), I deploy my DAG and I want it to get executed at 10:30īut for some reason that wasnt run today. ![]() I've read multiple examples about schedule_interval, start_date and the Airflow docs multiple times aswell, and I still can't wrap my head around:
