Unless I'm missing it, it appears like it isn't possible to launch a DAG job with initial inputs to the first task instance in the workflow (without specifying those inputs in the DAG definition)
Am I missing something? So for instance, I want to have user A be able to launch the DAG with parameter foo = bar, and user B to be able to launch the same DAG with foo = baz. In my use case, this would be hooked up to a RESTful API, and the users wouldn't necessarily know anything about DAGs or what's happening behind the scenes The closest I can think to accomplishing this is to generate run IDs in my REST API, store the (run ID, input) pair in a database, and retrieve the inputs in my first task in my DAG. But this seems like a very hamhanded, roundabout way of doing it. I'd much rather just create a DagRun with task_params that the scheduler automatically associates to the first task instance. Any thoughts?
