Hey, when we create a branch, do we still have the assets states and infos / metadata?

Sorry for the delayed response here. Along with your other question https://dagster.slack.com/archives/C02LJ7G0LAZ/p1674662987659429, the answer today is no. Each branch deployment is a clean slate in terms of stored asset materializations. We do have some features coming down the pipeline that may serve a similar purpose though. A new ‘branch io manager’ will be able to load asset data from full deployments, so you could run tests in a branch deployment with real data.
