Is it possible to run part of DAG in Metaflow? ex: I want to run just start step. other steps in a second run with resume.

We are working on a new "spin" feature that would allow you to run a single step at a time as a completely isolated execution. Meanwhile, for your resume use-case, you can simply "raise err” in the next step and resume. It's not the best solution but works for the most parts.

what are the timelines for this feature?

Sorry for the late response - in roughly 2 weeks

Very excited to see this!
