Random, but just upgraded all our pipelines from the old 0.xx to 1.x. Took about a morning, reason I like Dagster is that if we ever need to change off... it's all just Python code and super easy. Dagster just manages all the fiddly bits for us (and we love it). First commit for us was January 2021, been absolutely rock solid since then. We've been keeping up to date, but we still had a few crusty jobs using solids, but was super easy to just change them to be ops. 10/10 would recommend Dagster.
