"hello world" for dynamic partition etl is a nightmare. The inability to get hello world working with dynamic partitions/run keys is causing me to abandon dagster. Seems that the cost of repetitive tedious logic around i/o is much less than trying to piece together the dagster abstraction, given the examples/docs. Feels like every time I try to use frameworks like airflow, kedro, dagster, they all let me down as soon as I start doing anything dynamic.
