andrewgodwin opened a new issue #15140: URL: https://github.com/apache/airflow/issues/15140
It would be beneficial to larger/more complex DAGs to be able to label the dependency edges between tasks so that, in the graph view (and potentially other places), we can show this information to the user: ![image](https://user-images.githubusercontent.com/36182/113329516-e9ebc280-92da-11eb-92a1-2a0f5428780c.png) The proposed syntax for this would allow for use with both the `>>` style and `set_upstream` style of declaring dependencies: ``` mean_height >> Label("Output") >> print_result mean_height .set_downstream(print_result, Label("Output")) ``` There would be no runtime effect initially; it would just be for displaying and understanding the DAGs. I have a PR cooking for this, and will push a WIP of it and link it here shortly. -- This is an automated message from the Apache Git Service.
