Hi, My name is Alvaro and I am a junior developer who is writing his FMP (Final master project) about a project which uses Apache Airflow. I am interested in developing a new feature for Airflow which I think many people could use.
MOTIVATION I really think this is a very useful feature to add. There are times when you want to make a dag execution and you expect that execution to overtake the others already running, because it has priority over them. Now, this is not possible, because the tasks priority are static and only added when creating a dag, not when doing a dag run. CONSIDERATIONS I propose to add a parameter to the dag run API and Client endpoint named as 'priority'. This parameter will overwrite the tasks priority of the new dag run. Then, the scheduler will do the work as it does now. This will remove the need of creating several dags which do the same but with different priority parameters. Users are not affected by this change, because it is a change that adds an optional parameter that can be used or not. I will extend the AIP proposal when I get access to the Confluence AIP Draft. Thanks in advance.
