Hi, I have two questions around Flink deployment. I have done some research but I wanted to confirm my conclusions.
1) Is it possible to do a live upgrade of a Flink cluster from one version to the next without having to take down the entire cluster? (Imagining a rolling deploy where we only take down one JobManager or TaskManager at a time while the rest of the system continues) 2) Is it possible to upgrade a streaming dataflow without having to stop it? I see mention of "Versioning for DataStream programs" on the roadmap here: https://docs.google.com/document/d/1ExmtVpeVVT3TIhO1JoBpC5JKXm-778DAD7eqw5GANwE/edit#heading=h.qn8zyouct55x . Assuming these are not available today are they on the roadmap for the future? Any projected release that might have this functionality? Thanks, Chris
