Well, I would say then that in the second scenario it’s just rerunning the pipeline, and in the third it’s not running it at all

(I mean, in both the code may have changed, the only difference is that in the second case you’re interested in measuring it, and in the third,
you’re not, so it sounds like a user-specific decision).

Well, I would hope that in the second scenario step A is not rerun. Yes, in the third scenario, nothing is rerun. Your text in parenthesis is correct.

At any case, while I understand now what Martin meant, I still feel the function-based pipelines are the strongest option, because it sounds
like you’re looking for a way to dynamically build your pipeline.

I think you might be mistaken, because @<1523701205467926528:profile|AgitatedDove14> referred in None to the decorator approach, at the point where he rewrote the code. In terms of creating dynamic pipelines and cyclic graphs, the decorator approach seems the most powerful to me.
