Hey Fabian, thanks a lot for reaching out to the Flink community with this proposal! (Posting to the ML instead of creating a JIRA is a good idea for such questions -- you can create a ticket/tickets once the discussion here has come to a conclusion)
I have two comments: - You are listing Records/Kb in and Records/Kb out as cluster-wide metrics. I wonder whether we should rather show these metrics for each job, instead of the entire cluster? (or maybe both). My concern is that the cluster-wide metric is not really relevant as soon as you have jobs with different characteristics running on one cluster - You mention that the Flink UI is based on Angular 1. I've been thinking for quite a while now whether we should actually rewrite / migrate the Flink UI to React. Do you think we can re-use most of the work you'd be doing for this change when we migrate to React?
