how to create dags or jobs using this latest ui i dont see any option to do so

[@mohamedaminchairi]

I'd like to see more about setup and teardown tasks. I'm using airflow intensively but we create our pipelines based on a Yaml file. (custom framework) so our dependecies are taken from the structure of the yaml

[@MarcLamberti]

Will do

[@donnillorussia]

Please, do some "deep dive" tutorial on managing multiple airflow instances in a cluster like dev/prod. Never used git branching with airflow btw. What are best practices?

[@MarcLamberti]

Will do 🫶

[@JeanBzh]

good point, indeed

[@JeanBzh]

setup is just the first task, and teardown is the last task with a "all_done" trigger rule, what do these new labels bring ?

[@MarcLamberti]

Great question. I think the best answer is to look at the following tutorial: docs.astronomer.io/learn/airflow-setup-teardown
setup and teardown tasks have specificities that make them much more convenient to manage resources than a task with all_done. I will make a video about it very soon.

@@MarcLamberti I'll read it right away, thank you Marc

[@blind-tr1my]

i am currently have an issue with subtasks in apache airflow.
EXAMPLE:
let say there are 3 subtasks (in parallerl) which are already completed
and now two new tasks are added..
HOw do i make sure that only these two new subtasks are run? (instead of the entire 5 subtasks running)
Attempts:
from GUI perspective we have option called "queue up new tasks" that does the job.
I am coming from the script point of view , about how to activate this button/option
Could you please provide me with a hint/idea/suggestions (literally anything )

[@JeanBzh]

I suggest you open a stack overflow topic, I'm not convinced this comment has anything to do with "what's new in Airflow 2.7"

[@titowoche]

Please do make a video about setup and teardown

[@MarcLamberti]

Will do 🤓

[@user-xy7ed4xq5k]

Where do i find task logs ?

[@MarcLamberti]

On the UI

[@user-xy7ed4xq5k]

@@MarcLamberti earlier there was an option where we can click on task ( task box in the DAg visualization) and go to the logs of particular task. With the UI upgrade how can I navigate to the logs ?
