I created a first proof of concept of an integration between Meltano and Dagster. It automatically generates all Software Defined Assets from the taps, and dbt models and shows this in the UI.
This also allows you to easily run subsets of your data pipeline. In this example you can easily run all upstream assets that are used as input for the machine learning model (across different technologies).
I think it would also be cool to connect your dbt models to your BI tooling, to get the whole dependency graph from top to bottom 🤔
