I really like the way meltano easy the integration of OpenAPI andall teh good tap and target already developped.
I am also an instensive user of dagster. So mixing both would be...
Today I am using the excelent plugin dagster-meltano which does "meltano run tap-1 target-1" running the CLI. But with this you don't capture errors, the configuration of dagster is not easy, etc...
If we "capture" in memory what the tap-1 we can easily imagine to create ops / resources in dagster to integrate meltano. And leverage both.
I will look into the mentioned talk.
