I have a system which writes binary scientific data files as part of processing. Those files are the main output of my job. I’m trying to express this through dagster, and I’m finding it difficult, since Dagster wants me to express outputs through Python return values. Am I missing an existing tool or pattern here that would help me work with raw files as outputs from a step in the graph?
