We do have a doc describing when to use assets: https://docs.dagster.io/guides/dagster/enriching-with-software-defined-assets#when-should-i-use-software-defined-assets And in the image I added above, you could use dynamic outputs to create a "loop". A dynamic output allows you to yield an arbitrary number of outputs from an op, and then map over these outputs in a downstream op, running any per-output operations as needed.

I will check out wat you send me, thanks!!
